"insulation"

The iconic architecture of the three Kranhäuser buildings in Cologne’s former commercial harbour is reminiscent of the old loading cranes that could once be found here. While the two initial structures were designed as office spaces, the last in the collection – Kranhaus Nord – is entirely residential. This means there were high standards to meet with regard to impact sound insulation in this construction. Fortunately, Schöck Tronsole® type T offered the perfect system solution in this regard.Both the structural engineering and architectural planning processes for this residence had to be adapted accordingly to suit the high-end use of the building. Unlike the design of the office buildings, the bridge abutments are connected via an atrium that leads to the premium apartments rather than being separated.The main stairwell runs right alongside premium apartments, which means sound proofing was a key consideration. This was required not only due to standard building regulations, but also for the fact that “as a provider of luxury apartments complete with a whole host of amenities for international clients, people expect top quality. Thus, the decision was made to use the Schöck Tronsole® sound proofing system: A tried-and-tested solution for integration into stairwells.”

As a key part of the University of Lancaster's Preston Campus, the £32 million Engineering Innovation Centre provided the university and Lancashire based manufacturers with state-of-the-art teaching and research facilities. This helps to train an extra 500 graduates, including an increasing number of female students, gaining degrees in subjects such as mechanical, energy technologies and aerospace engineering. Throughout the entire project, there were a number of technical challenges that needed to be met. These include the building's proximity to a very busy roundabout, the floor to floor heights, physical security, the expected levels of solar gain as well as design detailing requirements. Having a total glazed area of 3,100m2, the aluminium curtain wall carries over 40 different types of IG units, along with high density foam inserts utilised alongside decoupling joints in the mullion section - achieving 50 Dnfw flanking sound reduction, as well as 37 dB sound reduction for noise outside the building. In addition to achieving high levels of thermal insulation, being fabricated from aluminium, the curtain walling frame elements can be recycled, helping to achieve the BREEAM rating of Excellent.

Hammerson House will be a world-class, 116-bed residential centre for the elderly Jewish Community in Hampstead. Newton Specialist Contractor Cast Contracting Ltd (CCL) were approached during the planning stages to develop a comprehensive waterproofing solution for the extensive basement.CCL recommended the installation of a Newton CDM water management system to comprehensively waterproof the extensive basement. First, they employed the 8mm Newton 508 membrane to the concrete retaining walls of the basement. The 50mm thick Fibran XPS 500-C insulation was then installed beneath more 508 membrane across the entire concrete slab. Additionally, Basedrain drainage channel was installed around the perimeter, including inspection ports to provide a fully maintainable system.This entire system is served by a series of complete sump and pump systems, each consisting of primary and backup NP400 pumps, high water level alarms, and battery backup systems. These are all controlled by Newton’s advanced Control Panel-Pro to ensure a failsafe system, even during a power outage.Finally, Newton’s 107F cementitious waterproof membrane was spray applied to the concrete upstands of the lightwells and lift pits in order to complete the continuous watertight solution.

Metalline’s glazed in Ultima aluminium insulated panels have provided a specialist touch to the recently completed Weybridge Business Park in the Borough of Runnymede. The commercial office park features a number of office buildings that have been refurbished as part of a redevelopment for Standard Life Investments. The bespoke glazed in panels which feature on the window surrounds to the 1st and 2nd floors were coated in PPC golden beach metallic and feature a fluted design that met the architects vision for the external envelope of the building. The aluminum outer face was fitted with extruded box sections to give the fluted appearance. The aluminium section was then sealed using specialist rivets designed by Metalline for this specific application. Each of the 2 metre panels were then vacuum bonded using Metalline’s new 6-metre vacuum bonding press. Ultima panels are traditionally specified in aluminium with either an anodised finish in natural silver, bronze, black or blue-grey or in a range of polyester powder coated RAL and metallic colours. They can also be provided with a noncombustible A1 fire rated core. Alternative facings such as perforated aluminium, stainless steel or can be incorporated to create a truly bespoke panel.

Nearly forty years after the lights were switched off at Battersea Power Station, a decommissioned Grade II listed coal-fired power station, located on the south bank of the River Thames, this much loved London landmark recently re-opened to the public following a transformational eight-year restorationApple Inc. will be leasing approximately 500,000 sq ft. across 6 floors of the central Boiler House and plans to move all of its 1,400 London employees to the new venue. This will make Apple by far the largest tenant at Battersea Power Station.221m² of Stravifloor Channel, a resilient high-performance floating floor based on floor channels containing steel springs as resilient supports was installed to decouple the acoustically critical listening, screening and control room spaces at Battersea Power Station.The added insulation material between the channels contributes to the acoustic optimization of the spaces by preventing the so-called standing wave effect to take place within the air void.During the installation of the acoustic floating floor, careful attention was paid to the many service penetrations as improper installation would most certainly lead to rigid connection which in turn affect the system’s performance.

The Canaletto residential tower at 257 City Road in London is located halfway between Old Street and Angel Stations in Islington, alongside the regenerated City Road Basin. It comprises a 31-storey tower with 190 luxury one, two and three bedroom apartments built to the standards of Code 4 Sustainable Homes Level 4.The tower is concrete frame and has a curving facade of metal and glass that breaks the volume into a series of three-to-four storey clusters. In turn, each cluster contains grouped balcony terraces, which are a striking feature of the building. The balconies are of steel construction connected to the concrete frame and as always with cantilever construction elements of this nature, one of the early design considerations had to be the prevention of thermal bridging.For the high specification Canaletto project the Schöck Isokorb® T type SK offers the ideal solution. It is a concrete-to-steel connectivity module that sits between the outer and inner structural connection points and blocks the outflow of heat through the use of high quality polystyrene insulation foam. The Isokorb® T type SK provides a clean and unobtrusive connection detail, minimises on-site assembly time and enables a high level of prefabrication.

Procter and Gamble is the largest multinational consumer goods company in the world with 65 brands ranging from home care to skin care. Project/doors:Manufacture, install and service over 70 industrial doors across 6 sites. The challengeP&G’s first goal against climate change was to reduce greenhouse gas emissions at its facilities. The UK Environmental Agency also regulates the emissions at P&G Thurrock under an Integration Pollution Prevention & Control permit. Another important factor at the facility is efficiency and any works must cause minimal impact on production.The solutionHart has supplied over 70 industrial doors to the site. High-speed doors and insulated fast action roller shutters allow efficient traffic flow while controlling the heat, odours and noise. LPCB approved fire shutters safeguard employees and keep the building compliant with the latest legislation. Regular servicing maintains the reliability of the doors and the efficient running of the facility.The successThe relationship between Hart and Procter and Gamble spans 30 years, with more than 70 installations across six facilities. We have worked together to maintain and upgrade these manufacturing facilities without disrupting production.

We all know warm roofs and joist zones are huge areas for air leakage and extremely hard to solve this problem. This warm roof structure for luxury apartments retrofit fit onto an already existing block of apartments in Tottenham was typically the icing on the cake for detail and performance. With the hand cut roof providing the client with multiple skylights, dormers and 360-degree turrets, this was going to be no easy task of getting the airtightness and vapour control secure and correct in a traditional method. Step forward Passive Purple! Rather than just covering the issues, once the hand cut roof was finished, the 220mm roof rafters were filled with a layer of spray insulation supplied by Lapolla UK. The dormers, skylights and turrets were then given some attention to detail with Passive Purple BRUSH before the final application of Passive Purple (spray applied) This gives this roof a complete airtight vapour control with performance like no other and getting around all of them circular details and angle’s galore this was just another simpler, easier way to get the job done right and guaranteed! Passive Purple liquid application saves the client and user so much time and so much less strenuous labour.

OverviewA sheltered housing accommodation owned by Bournemouth Borough Council were in need of a new smoke ventilation systemProject BackgroundSix blocks of sheltered housing accommodation owned by Bournemouth Borough Council were in need of a smoke ventilation system. The project was carried out to replace older ventilators that were proving unreliable and did not meet current requirements for energy performance.Project SolutionPowrmatic Krystalite louvres were selected from a shortlist following a tender exercise by Bournemouth Borough Council, and installed by Dorset Electrical and Fire Alarms (DEFA). They are located at the ends of corridors and stairwells, providing natural daylight and ventilation to common areas, with automatic smoke and heat ventilation in the event of a fire.Each ventilator is equipped with a manual switch for residents, as well as rain and wind sensors, to automatically close the louvres in bad weather. In addition, the warden has a manual override function to close the louvres at night, safeguarded by an anti-finger trap facility.Project ResultKrystalite ventilators feature high levels of thermal insulation, combined with a polyamide thermal break to minimise energy losses. Consequently, Bournemouth Borough Council will benefit from improved energy efficiency while ensuring the safety and comfort of its residents.

To design with people at the heart, acoustics and aesthetics played a key role in the system specification for this project. Helping to achieve the forward-thinking brief, Komfort’s Polar 54 slimline double glazed partitioning, acoustic Sonik doors and bespoke pivot doors were installed.Polar 54 was specified as part of the design due it to its slimline frame and acoustic ratings of up to 47dB (Rw); providing a flexible design solution that doesn’t compromise on performance. The minimal trackwork helps to create the impression of space and a seamless and high-end finish.To complement the design and performance of the Polar 54 system, Komfort’s Sonik doors were installed. The Sonik door range has been designed for ease of installation and integration with all of Komfort’s partitioning systems. This system also ensures high acoustic insulation is maintained through the use of an automatic drop-down seal.Aligning to the design brief of creating an innovative and memorable space, Komfort designed and installed an oversized pivot door. When the pivot door is pushed to, it creates the appearance of a glass wall dividing the dedicated space. This statement feature demonstrates Komfort’s capabilities for purpose-built systems which are tailored to meet design and performance requirements.

The fact that power stations produce high levels of noise won’t come as much of a surprise to anyone who has spent more than a few minutes inside one. Quite how dangerous these levels of noise can be, however, might.How Loud is ‘Too Loud’?To give you an idea of the sensitivity of the human ear, the average person can hear sounds down to about 0 decibels (dB), the equivalent of a whisper or rustling leaves, and people with exceptional hearing can detect sounds as low as -15dB.It is at the other end of the scale, however, that serious problems can occur. At around 85dB, you are likely to experience discomfort. As little as eight hours of continuous exposure to this level of noise can result in permanent damage to the inner ear, which is why 85dB is the maximum allowed under the Noise at Work Regulations. At 100dB, just fifteen minutes of exposure can cause permanent damage. And at 110dB the exposure time drops to around a minute before harm is inflicted. Pain is experienced at 125dB and hearing loss can be permanent. At 140dB or above not only is the damage permanent, it is also immediate.The Noise at Work Regulations stipulate that an ‘employer shall ensure that risk from the exposure to noise is either eliminated at source or, where this is not reasonably practicable, reduced to as low a level as is reasonably practicable.” And that “if any employee is likely to be exposed to noise at or above an upper exposure action value, the employer shall reduce exposure to as low a level as is reasonably practicable by establishing and implementing a programme of organisational and technical measures, excluding the provision of personal hearing protectors, which is appropriate to the activity.” In other words, an employer is expected to do everything they can, within reason, to protect their employees from the harmful effects of noise. And, no, it isn’t enough to simply supply a pair of ear-defenders.Noise-Induced Hearing LossThe damage caused by these dangerous levels of noise is referred to as Noise-Induced Hearing Loss or NIHL. NIHL can be caused by a single exposure to a very loud sound or by repeated exposure to even relatively low levels of noise over a long time span. In fact, according to research carried out by Xiaoming Zhou from the East China Normal University in Shanghai, even seemingly innocuous sounds, such as the whirr of a desk fan, can cause damage if exposure is consistent and long-term.To understand how NIHL occurs, it’s necessary to understand how hearing works.The generally accepted view is that sound waves strike the eardrum and these vibrations are translated into coherent information by the brain. It is slightly more complex than that. Sound waves do, indeed, strike the eardrum, causing the eardrum to vibrate. These vibrations are then transmitted through the ossicles (the small bones of the middle ear) to the cochlea, a spiral-shaped chamber filled with fluid and lined with tiny hair cells called stereocilia. The vibrations cause the fluid to move which, in turn, causes the stereocilia to move. The stereocilia’s movements generate neural signals with are picked up by the auditory nerve which ‘forwards’ these signals onto the brain where they are interpreted as intelligible sounds human speech, music, the beep of car horn etc.Exposure to the harmful levels of noise mentioned above can damage the stereocilia, breaking them or flattening them so they no longer vibrate as effectively or so they no longer vibrate at all. The result: impaired hearing or, in extreme cases, total hearing loss.The noise recorded coming from the dry cooling system at the Severn Power CCGT Power Station at Uskmouth B was between 130dB(A) and 135dB(A), a full 50dB above Noise at Work Regulations’ acceptable levels. Regarding dB(A), the human ear does not hear all frequencies with the same intensity. It is most sensitive to sounds in the 500Hz-8kHz range. Above and below this range the ear becomes progressively less sensitive. To compensate for this, sound level meters incorporate electronic filtering to correspond to the varying sensitivities of the ear. This filtering is called A-weighting and readings obtained with this weighting are referred to as A-weighted and signified as dB(A).The Wrong Kind of NoiseAlthough it was identified that the dry cooling system from SPX Cooling Technologies was generating these dangerous and unacceptable levels of noise, it wasn’t the cooling system that was creating the noise. In fact, it was the turbines that were the source of the noise. The steam roaring from the turbines at incredibly high speeds enters the main 5.5m steam ducts, passes up five risers and is channeled into the steam distribution manifolds. Not only does the steam enter the dry cooling system, the accompanying noise does, too. You might think that the 8mm thick steel from which the ducts are constructed would go some way to containing the din. Unfortunately, steel is extremely adept at transmitting noise and is, in many respects, the acoustician’s worst enemy.To make matters worse, when acoustics and soundproofing specialists, CMS Danskin Acoustics, were brought in by SPX and Uskmouth’s main contractors, Siemens, they discovered not only high levels of noise but also that the noise generated had a very low-frequency bias. Low-frequency noise is the most difficult to treat from a soundproofing perspective due to the excessive length of the wave cycle. This is one of the reasons people in apartments, terraced houses and semi-detached homes will often complain of the problems of bass noises intruding from neighbouring properties, as the walls and floors filter out the higher frequencies whilst the lower frequencies manage to penetrate. This can seem a little counterintuitive, as we imagine higher frequency noise to be more piercing. Their short wave-cycle, however, means they can be blocked out with relatively thin soundproofing materials.The low-frequency nature of the noise also meant that this wasn’t just a Noise at Work Regulations problem. Low-frequency noise can be particularly problematic to the population in the vicinity of the source of that noise. Low frequency noise is often not even ‘heard’ in the traditional sense. Complainants often won’t even realise that noise is the problem at all; instead they will describe ‘pressure sensations’ and ‘physical discomfort’, experiencing the incursion as vibrations. Areas of the human body can resonate when exposed to low frequencies. The chest, for example, can resonate at frequencies between 50Hz and 100Hz, and the head at frequencies between 20Hz and 30Hz. It isn’t unusual, therefore, for sufferers of low frequency noise to complain of anxiety, nausea and headaches. Often, they won’t even be aware of the root cause of their symptoms, instead attributing them to a virus or some mystery illness.A New Approach and a Sound SolutionSolutions for low-frequency noise issues typically involve wrapping the problem in significant quantities of acoustic insulation, with many standard solutions being as deep as 500mm to 700mm. The sheer volume of lagging required for an insulation-based approach to a project like Uskmouth, with a daunting 8,000m2 of ducting to be covered, would be expensive, time-consuming to install and prohibitively disruptive. What’s more, there were areas around the ducting at Uskmouth which simply wouldn’t have been able to accommodate such an excessive construction height of soundproofing material.Paul Absolon, CMS Danskin Acoustics’ Technical Director, responded to the challenge of creating a ‘thinner’ soundproofing system that would meet the necessary Noise at Work Regulations requirements but would be cost-effective and efficient to install. In order to minimise disruption to Uskmouth, an off-site simulation was created near Burton on Trent, using a large section of identical ducting with a ‘door’ sealing up either end. Within the duct were several very powerful speakers. For testing, highly sensitive microphones were placed in strategic positions along the outside of the duct to measure any ‘leakage’. Acoustic insulation solutions were conceived, implemented and assessed in this controlled environment with the assistance of Acoustic Consultants Muller-BBM and the installation company Western Thermal Insulations.Exploring a wide range of acoustic materials from CMS Danskin Acoustics’ industrial acoustics range, it was clear that a single product was not going to be able to solve the problem on its own, so Paul opted for a combination of products working in concert, layer upon layer.The first layer consisted of CMS HT1B elastomeric isolation pads, constructed from a polyurethane-bound rubber granulate specifically formulated to dampen and/or isolate noise and vibrations at source and independently tested by the Institute of Structural Dynamics at the Technical University of Dresden. The 50mm thick pads were bonded to the surface of the duct at a rate of nine per square meter, creating 300mm spacings; so, as well as the dampening effects of the material itself, the construction benefited from large, evenly distributed airspaces in its foundations. Sound waves move less effectively through dead air.The second layer consisted of 50mm-thick QuietSlab SVX3, a high-performance, mineral-fibre acoustic lagging. MIMA (the Mineral Wool Insulation Manufacturers Association) describe the acoustic insulation properties of mineral wool (and mineral fibres more generally): “Porous materials such as mineral wool work to control and reduce noise by allowing air movement into the fabric of the material. The fluctuations of air molecules – which form sound waves – move into the body of the mineral wool, where friction between the air particles and the material’s narrow airways cause sound energy to be dissipated as heat.”

The architect has created a connection with the outdoors in, utilising large fixed rooflights from Glazing Vision to bring daylight into the house and frame the surroundings.‘The most beautiful spot in the Netherlands’; that is the description of this country house in the marina ‘t Raboes according to the owners. Located on the Eemmeer, a place in the middle of nature, and away from the hustle and bustle of city life. The architect has created a connection with the outdoors in, utilising large fixed skylights from Glazing Vision to bring daylight into the house and frame the surroundings.Bringing in daylight with large minimalist skylights was a key requirement for the architect. The horizontal application of large glass surfaces demands a lot from the design and after many discussions, the architect was confident that Glazing Vision was the rooflight manufacturer that could implement what they had in mind.No framework in sight. Insulated glass with excellent insulation values. Glass that blends seamlessly into the architect’s design. A way to bring the outdoor feeling inside.Three multipart skylights have made this architectural vision become a reality.The back-to-back angles fit in very well with the rest of the modern contemporary interiors. To make it possible to darken the rooms, Glazing Vision has applied custom-made sun protection from Topshade.At the spot where the river Eem flows into the Eemmeer, architect De Kort van Schaik designed the country residence ‘t Raboes. The clients wanted to create a place where they could fully experience nature, but also withdraw from the hustle and bustle of the city.The house consists of three parts, connected by three covered terraces. Concrete walls and floors which blend seamlessly into the environment and large windows that frame the polder landscape.All energy on ‘t Raboes is generated locally. The solar cells on the roof of the marina building supply electricity. A heat pump that uses the surface water of the Eemmeer provides heating for the house and swimming pool.In the living areas, wood stoves have been used, all which use wood from their own grounds, providing readily available extra heating capacity.A beautiful contrast is created by the yellow epoxy bathroom furniture, designed by Sabine Marcelis. A piece of furniture consisting of a bath, wash bath and shower stands as a free-standing sculpture in the concrete bathroom. The skylight forms a completely frameless glass roof, which gives you the feeling of being outside even more.Sabine Marcelis states that she has designed her dream bathroom. The subtle rotation of the furniture gives you a fantastic view of the landscape from the bath.Taken aback by this stunning property, the architectural press has been impressed with all aspects of the design. De Volkskrant gives the Huis op ‘t Raboes five stars. “The Rotterdam architectural firm De Kort Van Schaik designed a house in which you live with the elements and at the same time are protected against them, thanks to a thick concrete coat.”

Benenden Hospital is a state-of-the-art private hospital in Cranbrook, Kent specialising in a wide range of discretionary healthcare and well-being services to individual and business healthcare members.• The original hospital opened in 1907 by National Association for the Establishment and Maintenance of Sanatoria - to treat postal workers suffering from tuberculosis. By 1951 the Association had disbandedand the Benenden Healthcare Society took over the sanatorium, dramatically expanding the services available.• Architects C A Vaughan Blundell were appointed to design a new atrium and welcoming area to enhance the patient and visitor experience.• The £55m project attained a Breeam status of ‘Good’.The SchemeThe scheme, designed by architects C A Vaughan Blundell with assistance from SR Architects Ltd, has created a wonderfully light and airy entrance atrium designed to welcome and create an enhanced patient and visitor experience with maximised natural daylight. The extensive breakout and catering facilities support theatres, en-suite rooms, outpatient department and ophthalmic suite along with diagnostic imaging, rest and recovery areas. The main contractor was Willmott Dixon Construction.The AdvantagesThe skylights have a unique ability to bathe interior spaces with diffused and glare-free daylight, which creates a stimulating and healthy environment. In addition, their heavily insulated composition eliminates glare and hotspots, thereby reducing the load on temperature control systems and the need for artificial lighting.They provide additional light in the large atrium projecting it deep into the interior. They were specified complete with highly insulating Nanogel which achieves an impress U value of 0.28W/m2K, helping the project attain a Breeam status of ‘Good’. This is particularly impressive given the amount of curtain walling and clerestory glazing involved in the scheme.Kalwall skylights can be manufactured to large spans up to six metres. The aluminium or thermally-broken grid core with interlocking I-beams gives Kalwall incredible strength. The lightweight system reduces the need for supporting structures while offering the highest protection in terms of wind-borne debris and resistance to impact, abrasion and point loads. The exterior face is colour stable and includes a UV resistant, self-cleaning surface. This means that normal  rainfall helps to keep the surface free of dust and dirt while at the same time retaining its original colour during the weathering process. Furthermore, the inclusion of an erosion-prevention barrier protects the interior from weather exposure and the risk of fibre-bloom, cracking and crazing.The CommentsGeoff Holden, Senior Technician at C A Vaughan Blundell comments, “The use of Kalwall represented the best value balance of energy saving and cost and provided us with the ideal way to achieve spatial daylighting within the requirements of Part L”Jane Abbott, Hospital Director, “We want to ensure our patients have an excellent, efficient and streamlined experience from the moment they arrive until the time they leave.”

Chelmsley Wood Shopping CentreBauderflex bituminous waterproofing systemSynopsisChelmsley Wood Shopping Centre, located in East Birmingham, was experiencing leaks with their current flat roof waterproofing system and so they needed a quick, high quality solution to remedy the situation. Although competitors had suggested the only option was to strip the roof, Bauder found a more cost-effective answer by using our in house Troxler Moisture Gauge to identify any areas of wet roof construction, removing the saturated areas and then overlaying the whole roof area.Bauder Building BoardProject:Chelmsley Wood Shopping Centre Location:BirminghamProject Type:RefurbishmentRoof Area:4500m²Specifier:Black Cat ConsultancyApproved Contractor:BBR Roofing LtdProject challengesThe works were to be undertaken in the middle of winter on the existing single ply covering which kept freezing when the operatives were drying the surface.

Ilona Rose House with its unusual rose-coloured 3D printed façade is a new-build, mixed-use project spread over 13 floors, including a 4 storey, basement with a quarter natural light. It has transformed the former site of the famous Foyles bookshop on Charing Cross Road, boasting outstanding new shops and restaurants, along with new pedestrian walkways, public realm and roof terraces.The unique building has been designed by MATT Architecture for main contractors Sir Robert McAlpine and offers 150,000 sq ft of office space, 20,000 sq ft of retail fronting on Charing Cross Road and a brand-new public courtyard with 15,000 sq ft of restaurant and bar space.The upper floors comprising of offices exploit the stepped massing of the building to create over 12,000 sq ft of planted external terraces for the benefit of the occupiers and to enhance the environment.The south-west facing terraces, nicknamed ‘the hanging gardens of Soho’ will provide external amenity space for every single level of office. It is here that Radmat’s waterproofing and insulation products were chosen for their tried and trusted properties. PermaQuik Hot Melt Bitumen Waterproofing System was used on 95% of the roof areas, multiple roof terraces, Greek Street Tunnel and James’ Courtyard.

Welcome to 120 Moorgate, a grade A office in the City of London. 3,000m2 of AGC ipasol Neutral 70/37 solar control double-glazing units and matching spandrel glazing was chosen for the facade of this extensive refurbishment project completed in 2020.In order to meet the demands of today's contemporary workspaces, a new facade was needed in order to improve the energy and acoustic comfort for occupants. With seven floors of full-height glazing, the ipasol Neutral 70/37 double glazing specification allows for the highest level of daylight and connection with the outside environment whilst protecting against overheating thanks to its solar gain reduction properties (g-value of 0.37). The fastest growing use of energy in buildings is for cooling, so harnessing existing technologies such as solar control glass can contribute to a sustainable building strategy.A low U-value of 1.0W/m².K was also a given, in view of the facade's thermal insulation requirements. Laminated glass was also incorporated in the specification of the double-glazing units as an acoustic enhancement to help protect against nuisance noise and also as a safety measure since the full-height glazing is accessible from interior spaces.Design work by Darling Associates and installation undertaken by specialist facade contractor Anglian Architectural.120 Moorgate is rated BREEAM Very Good.

Celebrating its 150th anniversary in 2019, St. George’s Weybridge – a Roman Catholic private day school in Surrey – marked the occasion with the introduction of an exciting new architectural development.Transforming its existing, functionally simple sports hall into an inspiring, beautifully designed facility, the College’s accommodation brief comprised a premiership level hockey pitch and six-court sports hall, as well as a strength and conditioning suite, dance studio and flexible multi-use areas for group activities, meetings, presentations, exhibitions, open days and ‘match teas’.Designed by global architectural practice Scott Brownrigg, the architect’s vision was to create a contemporary and timeless building that would inspire students to achieve their very best.With plans including a stunning tree canopy-like roof structure draping over the internal spaces, the roof needed to achieve 30m clear spans across the main hall and the design needed to be clever and sensitive to the fact that the site’s location sits within the green belt.

Located in West Kensington on the Springvale Estate, ‘Tavener Court’ comprises eight one and two-bedroom flats as well as two three-bedroom houses, spread across three floors.Externally, the scheme features the StoTherm Mineral external wall insulation system, which has been finished with StoSilco silicone render in a pale shade of yellow, and a variety of StoDeco three-dimensional profiles to add architectural detailing across the building. With 1,000 colours to choose from in the StoColor system, the Sto render offered extensive design flexibility for architecture and design company, NORR. It has also provided a high level of water repellence and water vapour permeability, making the façade resistant to the build-up of dirt and reducing the growth of algae and fungus. The StoDeco profiles were specified to create window surrounds in pure white, corner detailing around the roof area, and a decorative band course across the façade. Manufactured from Verolith, which comprises 90 per cent perlite, the StoDeco profiles are highly resistant to weather and other environmental factors. Light in weight and easy to work with on site, the products are quick to install and form a durable bond with the render. 

A £40 million investment, 13 roof areas, eight different roof levels, and a steady stream of visiting students to keep happy throughout – the University of Reading (UoR) Library’s complete refurbishment was a large and challenging project spanning three years.Originally opened in 1964 and later extended in 1985, the library’s internal and external revamp was designed to increase space, improve facilities for individual study, provide better access and security across the building, and improve energy efficiency.In addition to a new-build Café extension, a new entrance canopy, a new ground-to-roof level lift and stair core extension – each featuring a new flat roof area – there were also 10 existing flat roof areas refurbished, coupled with the replacement of windows and re-cladding of the building’s exterior.Following a competitive tender based on an outline specification, Owlsworth Roofing, Sika Sarnafil single ply flat roofing specialists, impressed with the level of detail included in their quote and were awarded the contract by main contractor ISG.Roofing:Sika® Sarnafil G410-12 ELF.Sika® Sarnafi G410-12 EL.Sarnavap®-5000E SA.Sarnavap® HD SA.Primer 600.Sikatherm® PIR Insulation and Sarnacol®-2162.

Architects: Woods BagotLocation: Wiltshire, UKPhotography: Will PryceMaterial: NATURSOFFIT-W CladdingFinish: RustikThe project by the Woods Bagot architecture studio for the library at St. Mary’s Calne School re-centres the space as the hub of academic and social activity. Completed in 2020 and located in the British county of Wiltshire, the project maintains the school’s traditional aesthetic, all while incorporating a central garden with apple trees.The library’s faceted ceiling is a central part of the design, which evokes spreading tree branches. All of the wood panels are held up by an iron truss structure connected to large pillars, simulating the vertical nature of trunks. The properties of Parklex Prodema’s false ceiling allow continuity for the wood from the interior to the exterior, making it visible through the clerestory windows.The triangular panels that make up the complex faceted geometry are resistant, long-lasting, sustainable, and maintenance-free. They were custom manufactured for this project, including perforations for acoustic purposes, allowing sound to pass through the panel to be absorbed by the insulation behind it.The natural Okume wood panel selected by the architects provides a warm, welcoming atmosphere, creating a point of inspiration for learning. Combined with the garden landscape around it, the continuous ceiling magnifies the building’s appeal and integrates it into his surroundings.

Efficient Approach Dramatically Reduces Turbine Noise at CCGT Power StationsTen years after it was first used at Uskmouth, this innovative approach to soundproofing that reduces insulation depth by up to 76%, is once again commissioned in France.Dangerous Levels of NoiseModern dry cooling systems offer many benefits over traditional systems in CCGT power stations, but they have the disadvantage of being a complex source of noise transmission. The turbine noise recorded coming from the dry cooling system at the Severn Power CCGT Power Station at Uskmouth was between 130dB(A) and 135dB(A). Exposure to these levels of noise, a full 50dB above The Control of Noise at Work Regulations 2005 “upper action level”, will cause both immediate and permanent damage.When acoustics and soundproofing specialist, CMS Danskin Acoustics, were brought in by SPX Cooling Technologies, designers of Uskmouth’s dry cooling system, they discovered not only high levels of noise but also that the noise generated had a very low-frequency bias, the most difficult noise spectrum to treat.Solutions for low-frequency noise issues typically involve wrapping the problem in significant quantities of acoustic insulation, with many standard solutions being as deep as 500mm to 700mm. The sheer volume of lagging required for an insulation-based approach to a project like Uskmouth, with 8,000m2 of ducting to be covered, would be expensive, time-consuming to install and prohibitively disruptive.The New Approach proven at UskmouthThe challenge of producing a soundproofing system that would be cost effective and efficient to install was taken up by CMS Danskin Acoustic’s Technical Direct Paul Absolon. CMS Danskin has a reputation for effective, high quality acoustic solutions tailored to the specific challenge, and this solution was no different.Exploring the wide range of acoustic materials from the company’s industrial acoustics range, Paul opted for a combination of materials working in concert: the unique CMS HTIB elastomeric isolation pads, constructed from a polyurethane-bound rubber granulate with excellent dampening and isolation characteristics; QuietSlab SVX3, a high-performance, mineral- fibre acoustic lagging; and WBKT Acoustic Barriers, a high-density, barium-sulphate-loaded thermoplastic polymer, which is thin, flexible and easy to work with.By using a bespoke combination of materials which each tackled specific aspects of the problem, CMS Danskin Acoustics were able to create a soundproofing solution with a construction depth of just 170mm, between 66% and 76% thinner than the 500-700mm standard solution. Disruption was minimised and material costs reduced.Once complete, the system was rigorously tested by SPX Cooling Technologies and Uskmouth’s main contractor, Siemen’s Energy. CMS Danskin Acoustics’ solution had reduced the noise generated by 39%, to just 82-83dB(A), under the 85dB “upper action level” listed in The Control of Noise at Work Regulations 2005.Peter Ullrich, project director, Siemens Energy, commented at the time:“Effectively controlling noise and reducing sound emissions was a top priority for us in the Uskmouth project. Not only was it essential that the dry cooling system satisfied all the legal acoustic obligations and regulations but just as important was that neighbouring properties were not disturbed by additional noise levels.”Repeat Success at LandivisiauTen years on, the same successful approach has been applied to the dry cooling system at the new CCGT Power Station at Landivisiau in Brittany, north-western France. Also built by Siemens, the dry cooling system was supplied by SPG Dry Cooling. In the case of Landivisiau, even greater sound reduction was required, from approximately 140dB(A) to below The Control of Noise at Work Regulations limit of 85dB(A).To meet this challenge, SPG and CMS Danskin collaborated on extensive testing at the acoustic testing laboratory of SRL Technical Services. The reductions achieved during testing as part of the specification process were some of the largest reductions in sound ever measured at SRL.Once the specification was confirmed, CMS Danskin worked with SPG to ensure that materials for the multi-layer acoustic solution were prepared and delivered efficiently so that SPG’s installers always had the correct materials on site. The installation of the acoustic soundproofing was completed in October 2021 and the power station entered commission as planned in April 2022.“CMS Danskin Acoustics Limited successfully supplied the acoustic material package for the project which was tested at SRL to give an overall lab test reduction of 68dB Rw.”Robert Hill, Project Manager, SPG Dry Cooling

A residential developer approached Hush Acoustics after an acoustic test conducted on their project in St Leonards on Sea failed to achieve the acoustic compliance level needed under Approved Document E of the Building Regulations.The problem stemmed from a separating wall between two bedrooms which was constructed using a timber stud wall and had an overall thickness of 170mm. Its acoustic design was adequate on paper, but there was one issue that had not been correctly treated.One of the rooms measured 37m3 and the other 29m3 in size, with one notable consistent feature being a screed laid over a concrete floor.An airborne sound insulation sample test was carried out with no floor covering in place and this revealed a result of DnTw+Ctr 31dB.Levels of ‘flanking’ sound were significant - this meant sound was passing under the separating wall via the floor screed. The solution proposed by Hush Acoustics was to install Hush Mat 15 over the screed floor in both rooms.The effectiveness of this solution was evident in the follow-up test result of DnTw+Ctr 44dB. Whilst this result would be regarded as an average performance in most other types of buildings, the improvement here from a poor DnTw+Ctr of 31dB to 44db showed that Hush Mat 15 had delivered significant improvement and provided a solution to flanking transmission sound sources.The ensured the residential development satisfied the requirements of Approved Document E.

This Edwardian home was transformed inside and out in 2021. Part of the renovation included changing the original single glazed, draughty timber sash windows. The sashes were previously painted shut to minimise heat loss, but this was proving both inconvenient and ineffective. The homeowners wanted to find replacement windows that were indistinguishable from their original timbers but in a low maintenance form that offered significantly better security and thermal efficiency. Having spent months looking around for the right solution, the homeowners found Roseview and, specifically, Ultimate Rose. Being the most authentic window on the timber-alternative market, they would match their original timber sashes like for like but with this maintenance free alternative. The windows were finished in a chalk white texture with an Edwardian astragal bar design, seamless run-through horns, deep cills, Secure by Design accreditation and shark fin limit stops throughout. Additionally, Ultimate Rose comes with ‘A’ rated energy efficiency as standard. For the homeowners, this means lower heating bills month-to-month and a reduced carbon footprint. This is due to Roseview sash windows being double-glazed and fully weather-sealed, unlike the home’s original timber windows. As a result, the homeowners now have sash windows that never need repainting and will naturally keep their home insulated and secure without sacrificing authenticity.

HMS Caroline – Museum ship... CHALLENGE HMS Caroline, the last surviving vessel from the 1916 Battle of Jutland, now rests in the Titanic Quarter in Belfast. After a second life as floating Headquarters of the Royal Navy during World War II, this living legend will continue to serve the country as a museum ship. For this purpose, however, extensive restoration appeared to be essential. The key requirement on HMS Caroline was to avoid penetration of the deck surface. To safeguard its historic heritage against damage, the Royal Navy sought a reliable waterproofing solution. SOLUTION Versatile and impenetrable! What used to be the properties of this battle cruiser, happen to apply to the RENOLIT synthetic single ply roofing membranes as well. That’s why RENOLIT ALKORPLAN was heralded as the optimal solution for the refurbishment of the ship’s gun deck. The lead grey RENOLIT ALKORPLAN A provided an ideal modern day solution with an impressive finish. On top of a new layer of insulation board, the calendered and laminated fleece-backed PVC membrane was fully bonded with a combination of the RENOLIT ALKORPLUS81068 polyurethane adhesive and the universal RENOLIT DUALFIX81065 glue. RENOLIT ALKORPLAN stands out above the competition given its excellent weldability, simplicity of detailing and overall versatility. Once installed, ongoing maintenance of the membrane will be minimal with a predicted life expectancy in excess of 35 years (BBA approved). On 31st of May 2016 the freshly refurbished HMS Caroline stole the show as a fitting backdrop for a commemoration honouring its centenary. 

 Divided into time slots so school life could go on as smoothly as possible during the restructuring, the renovation work involved changing all the functions of the educational establishment. A structure with entrances on either side, limited storage space for materials, the need to create various secure entrances to the institution consecutively according to the work phases… The BW Dumot architectural firm met these high-stake challenges with agility in organisational terms. Of course, by choosing a ventilated facade solution on a subframe and products renowned for their ease of installation and great resistance, the firm was able to optimise the External Thermal Insulation (ETI) phase.Changing the perception of the institution through the building envelopeLocated in a so-called sensitive neighbourhood, Paul Eluard Secondary School was ageing, with deteriorating facades. Its new generation design had to mark a change in order to both encourage residents to see the institution in a new light and help the students to reclaim the school.Since the college is located in a green space, away from the centre but overlooking the entire city below, the architectural firm chose a sleek design, a smooth and structured white mineral look, and the PAPYRUS finish (crumpled paper). In this way, while aiming for an understated look, the firm was able to create a strong contrast with the school’s surroundings, so that it would stand out and become a landmark.It was through the building envelope and the treatment of the facade that architect Barbara Dumont was able to express this aesthetic preference.

When developing new buildings, it is always important to consider the environmental impact. Responsible sourcing of materials is high on every priority list, along with reducing waste to landfill. But what about the local impact, such as the effects on local wildlife? A living roof/green roof system, such as the one installed by the Premier Contractor at Seaford Head Golf Club, is a very clear example of the steps that can be taken towards reducing this impact and providing an alternative space for wildlife to inhabit. A warm roof system was installed onto a structural plywood deck, after which a vapour barrier and insulation boards were mechanically fastened to provide both thermal efficiency and air leakage control. After the underlying installation had been suitably restrained in accordance with a site-specific wind uplift calculation, the roof membrane was mechanically fastened to complete the waterproofing system. Our PVC roof membranes have been tested and can be utilised without the need for additional root prevention barriers (test standard EN 13948), and because PVC is extremely lightweight, they are the perfect choice for these applications, reducing pressure on the underlying structure. In conjunction with our Living Roof/Green Roof specialists, a site-specific living roof system was supplied and installed over the completed waterproofing.Waterproofing System:DANOSA Single Ply 1.5mm - AnthraciteConstruction Type:New BuildWarm RoofSector:LeisureApprox.

Over the next ten years Nine Elms will see 20,000 homes built, along with new schools, parks, cultural centres, a pedestrian and cycle bridge over the Thames; and the opening of two new London Transport underground stations as part of the Northern Line extension. The residential and commercial heart of this huge development is Embassy Gardens, London's new diplomatic precinct on the riverside. The first release of apartments in Embassy Gardens is the Ambassador Building, adjacent to the new US Embassy. It comprises six distinct cores, which house not only the residential apartments boasting high ceilings, abundant natural light and walnut parquet flooring throughout – but also a fully equipped private members club to rival the best in any international hotel.Inevitably, the development has attracted a sophisticated level of residents who demand the highest standards of detail throughout these buildings; and one of the key features is the wide variety of balcony types, each governed by unit size and orientation. The specific requirements at the Ambassador building involved the Schöck Isokorb® T type K, K-WU an SK. The diverse range of Schöck Isokorb® T load-bearing thermal insulation products guarantees totally verifiable performance standards, meets full compliance with the relevant UK building regulations and offers BBA Certification and LABC Registration. 

The Höllentalanger, at 1387m, short of halfway during the initial ascent from Germany's highest mountain, the Zugspitze, is a 'hut' millions of climbers have found shelter since 1893. Despite modernisation over the years however, the building had to be closed in autumn 2013.A replacement building was needed – and quickly too. Stephan Zehl, an architect from Munich, won the tender with his three-level, stepped building design. It has pent roof borders, which protects against avalanche risk from the eastern side; and meets all necessary current standards in providing dining facilities, equipment rooms, drying and shoe rooms and comfortable accommodation to sleep 100 people.During autumn and winter, all paths to the Höllentalanger are closed-off, as the Alpine climate makes it impossible to work for eight months of the year. Even in good weather, there are only walking tracks to the Höllentalanger, with no road access at all – so everything had to be flown in by helicopter. Rapid assembly and efficient transport costs were therefore critical to the budget and a combination of timber and pre-cast element walls were the chosen method of construction. Core-insulated prefabricated element walls were supplied for the ground level building. Due to the extreme temperature fluctuations, the concrete is subjected to pretty extreme expansion and contraction conditions. To counter this and to combat thermal bridging, it was important to install Schöck Thermoankers.

Glazing Vision worked closely with Architect, A R C Architecture Ltd, and Contractors, Matrod Frampton Ltd, on this incredible project located in Lymington, Hampshire, where the client was looking for their new pool room extension to include a large, flat rooflight, creating a peaceful and naturally lit room, perfect for a relaxing swim. They were also looking for a rooflight within the loft area of the home to allow natural daylight and ventilation to the space.Glazing Vision’s Flushglaze Fixed Multipart Rooflight in Slate Grey Matt was specified for the roof of the pool house, which was an impressive 3800mm x 10360mm in size, which almost mirrors the size of the swimming pool below.Bespoke glass was selected for this particular project. The double-glazed outer pane was made up of heat soak tested, toughened glass which offers a greater resistance to thermal stresses and provides better protection against glass breaking, reducing risk of injury, essential with a pool directly below.Argon gas filled the space between the panes of glass which helps insulate the room and minimises the transfer of heat through the glass along with a black warm edge spacer which is an insulating plastic composite material that becomes a barrier to heat loss.The inner pane consisted of heat soak tested, toughened, PVB laminated glass which prevents glass shattering under impact by holding the shards together on the membrane so they cannot become lethal, and includes a soft coat low E rating of 1.1, helping with the energy efficiency of the room by reducing energy costs.The product was tested to class 1 in accordance with CWCT TN66/67 which is essential for rooflights which might be walked on for occasional cleaning/ maintenance activities, and which will therefore need to support both the weight of people on the glass and their equipment, which may be required on this occasion.The rooflight was supplied in 6 sections with internal back-to-back angles at the joints between each section. The 6 sections were sized to achieve an equal split when viewed from underneath.Our Skydoor Electric Hinged Access Rooflight was specified on the roof of the loft space which is ideal for ventilation and regular access, and offers natural daylight to the space below. Intelligent actuators ensure synchronized operation between the two supporting mechanisms, so the Skydoor opens to a maximum 87° in one fluid, trouble-free motion, providing you with easy access to the space above.The glass was a double-glazed unit comprising of a heat soak tested, toughened, soft coat low E (1.1) outer pane, with Argon Gas within the space between the panes and black warm edge spacer, with the inner pane consisting of heat soak tested, toughened, PVB Laminated glass, and was also tested to class 1.Both rooflights were expertly installed by our sister brand, Glazing Renovations.“Glazing Vision were helpful in explaining the two different upstands required for the different glazing systems. The installation team were helpful and carried out their work in a professional manor.” – Steve Davies, Site Manager, Matrod Frampton.

City of London Academy Shoreditch Park by Feilden Clegg Bradley Studios forms a part of The Britannia Project, regenerating a thriving London community with new facilities and amenities including new housing, a new school and community leisure facilities. Built to cater for the anticipated expanding population, the new development forms a harmonious addition to the existing neighbourhood with new, high-quality public spaces. The new secondary school for 900 local students plus a 200 student sixth form school had complex underground constraints to take into consideration in the design process, a challenge which informed every part of the building, including the choice of flooring and its installation in the school sports hall. Proposed Crossrail tunnels beneath the building meant the sports floor had to be able to cope with a much larger amount of structural movement than what would be considered normal for a building of this kind. Junckers’ technical department worked closely with the architect exploring a number of options to finally help them arrive at a solution which could accommodate an unusually large amount of structural movement and at the same time retain the sprung quality of the floor for sports and other activities. Junckers Approved Contractor V.A. Hutchison fitted Junckers 22mm solid Ash Champion over New Era battens with 125mm insulation between battens. Line markings for four badminton courts as well as basketball, netball and handball courts ensure the sports hall will serve the school and the wider community as a hub for multiple events and activities. The floor is area elastic and fully complies with EN 14904 class A4, a high-performance sprung floor which will serve the school and community for decades to come. A 22mm Junckers sports floor can be sanded and refinished up to ten times without losing performance, and with regular sandings in 12-year intervals, a lifespan of 60+ years as set out by the RIBA 2030 Climate Challenge can easily be achieved. Funding for schools issued by the Department for Education is now dependent on fulfilling strict sustainability criteria. Junckers has independently verified certification to show its flooring fulfils these criteria, In addition to the sports hall, Junckers flooring was specified for the school’s main hall, which is used for drama and other activities. The original specification was for a vinyl floor, but as a more sustainable solution, Junckers’ 22mm Nordic Oak in the Classic grade was selected. V. A. Hutchison Flooring installed the oak floor on New Era battens with 125mm insulation, including an area of 91 m2 of extra battens for support in the main hall. Jo Gimenenz, Architect at FCBStudios added: “We have worked with Junckers for many of our projects, CoLASP being one of the most recent and they always provide an excellent technical service. Particularly so on this project where we had to overcome a complex structural movement joint detail in our ground floor Main Hall, due to proposed Crossrail tunnels beneath the building. A Junckers flooring system was also installed in our Sports Hall. For this space we opted again for a solid timber flooring in lieu of a vinyl topped raised floor as it was a more sustainable solution.” 

URSA storey’s high with new Whitechapel development Global insulation manufacturer, URSA, has seen some 25,000 m2 of its specialist insulation materials specified and installed at one of the capital’s largest residential development projects in recent years. Ian Claydon, Technical Manager for URSA UK, describes the specification through to installation journey: “The Silk District is a new development located close to Whitechapel Station and within walking distance to the City of London. The Whitechapel based scheme compromises three residential blocks set around a piazza with private landscaped gardens. New commercial space on the ground floor of The Silk District will welcome many new and exciting restaurants, cafes, bars and shops. The Borough is considered an important area of regeneration for London and will meet the aspirations of neighbouring Shoreditch, Brick Lane, Spitalfields Market and Bethnal Green all of which are less than a 10-minute walk from the development.  “Our work with the London based property development company leading the scheme, Mount Anvil, began in November 2018. We provided advice and guidance on making the correct choice of materials, achieving compliance with Building Regulations (thermal performance, fire resistance requirements and resistance to rain penetration) and compliance with the NHBC Standards. We also provided numerous thermal models, U-value calculations and associated condensation risk analysis. The Mount Anvil team were undoubtedly impressed with the speed and quality of URSA Technical Services. “We were involved with external wall construction as well as the design of a brick clad rainscreen system and continued to work extensively on the scheme throughout 2019 as the design developed further. Work was delayed at the beginning of 2020 due to Covid and re-started in July 2020. Ian explained: “Collaborating with the client in these very early phases ensured that they were able to select a product that is entirely right for each and every one of their primary and secondary needs. Planning was critical within the design and roll out and meticulous attention to detail was applied during these initial phases and throughout. Key products installed included URSA’s Cavity Batt 32 & Walltec 32 – 12,000m2 and URSA Acoustic Roll - 13,000m2.   URSA Walltec 32 is a lightweight, non-combustible, semi-rigid glass mineral wool slab treated with silicon based water repellent. It is faced with a black glass tissue on one side and are ideal for use behind rainscreen cladding systems in both new build and refurbishment projects.URSA Cavity Batt is a lightweight, semi rigid glass mineral wool slab treated with silicon based water repellent. It is suitable for use in both fully and partially filled masonry cavity walls up to 25m high.Mark Guest, Regional Sales Manager for URSA UK continued: “URSA Walltec proved to be the ideal choice due to its outstanding fire performance qualities, with a Euroclass rating of ‘A1’ making it totally non-combustible and the ultimate in safety specification for behind cladding systems. URSA glass mineral wool is manufactured from an abundant, sustainable resource and utilises at least 50% glass waste. From an installation perspective, the black glass fleece tissue facing means that the product could be used behind open joint cladding without being seen.“The Cavity Batt is available in a wide range of thicknesses, ensuring the client was able to meet all appropriate Building Regulations and standards. Our new generation URSA TERRA mineral wool has a ‘soft touch’ feel making it easier to handle and install whilst still maintaining its excellent mechanical properties.“There were several other over-arching factors to consider within this scheme and those included the sheer size and scale of the site and its location in a packed city centre. The lightweight nature of both products meant that they could be compressed therefore saving time and money on transport, effectively halving the number of journeys needed. This meant that more products could be delivered to site and stored in an area where space was at a premium. “Work is now once again very much underway with an anticipated completion date of early in 2021. The property market is thriving once again and Whitechapel is becoming recognised as a hotspot for investment and is now being considered the destination of choice for many new businesses. Our distributor partner, Encon Insulation in Dagenham, worked closely alongside us during the project” Ian concluded: “It’s fantastic to see two of our core product specified at this major residential development. We have enjoyed a collaborative, partnering approach with the client throughout. The client has been keen to specify the safest, most durable, sustainable and quality product available on the market today and we’ve been pleased to support them in their design journey through to installation.”
