"insulation"

The Chiswick Point development, at Bollo Lane, in West London, is a £20m contemporary mixed-use residential scheme offering 124 one, two and three bedroom residential apartments, including three penthouses. A sustainable approach was important, with all of the units designed to meet Level 4 of the Code for Sustainable Homes, and the Lifetime Homes code. Constructed in two blocks of six and nine storeys, the frame is mainly reinforced concrete, with the concrete frame floors and cladding providing thermal mass, which absorbs energy and slowly releases it to help reduce temperature fluctuations.Long continuous ribbon balconies provide solar shading to the two blocks and provide the residents with a very pleasant outlook across the London Wildlife Trust nature reserve at the rear of the development. The continuous balconies are a major feature of the scheme and with several hundred metres of them winding across the two blocks, effective thermal insulation was imperative if thermal bridging is to be avoided. To minimise any condensation problems and subsequent mould growth as a result, plus the avoidance of thermal outflow, Schöck Isokorb® T type K heat-insulating load-bearing elements are installed at various strategic positions along the large expanse of balconies. The Schöck Isokorb® T type K provides high thermal resistance by using stainless steel bars to act as tension and shear reinforcement, plus high-strength HTE pressure bearing modules.

The 'HOOLA' in Tidal Basin Road in East London, gateway to the soon-to-be regenerated Royal Victoria Docks area, has transformed a brownfield site into two rippling 23 and 24 storey glass towers, that offer 360 apartments with a mix of studios, along with one, two and three-bedroom units.The buildings are super-insulated and the concrete frame will act as a heat sink – absorbing heat on warm days and releasing it back into apartments when it cools. An innovative link-up with the neighbouring ExCel Exhibition Centre will also see excess heat piped directly into the two towers. This will provide all the necessary heating and hot water requirements and significantly reduce maintenance costs by doing away with the need for individual boilers. A critical design requirement for such a super-insulated building was the avoidance of any risk of thermal bridging at the many concrete-to-concrete balcony connectivity points – so highly efficient structural thermal breaks were required throughout. The preferred solution was the Schöck Isokorb® T type K for cantilever balconies.Luke Smerdon-White, Technical Director at Thorp, takes up the story: "We had to design, manufacture and deliver 1410 precast concrete balcony sections that had to then be cast integrally with the in situ concrete structure." "The exposed front-face is curved, with almost 50 different dimensional configurations, while the internal face has a facetted line that had to correlate with the glazing line and opening doors."

The “Wohnpark in der südlichen Luisenstrasse” residential project was built in Karlsruhe in 2015. At the client’s request, architects AGP Generalplaner GmbH designed the building with enhanced impact sound insulation. Schöck Tronsole® was chosen as the impact sound insulation system for the stairs.Spacious rental and owner-occupied apartments with 1, 2 and 3 bedrooms were designed on a floor area totalling 18,000 m². All of the stairs in the buildings comply with the requirements of soundproofing level III as per VDI 4100 or DEGA class B. Specifically, the measured standard impact sound level of the stairs and landings ranges between 32 dB and 38 dB. These levels are about 10 dB better than the required standard impact sound level of 46 dB. By comparison: A reduction of 10 dB is equivalent to reducing the volume by half. The residents in the complex in Karlsruhe will notice this difference quite clearly. By not being able to impact noise from the stairs. The stairs are soundproofed using Schöck Tronsole® type F on the ceiling slabs while Tronsole® type Z separates the landings from the stairs and outer walls. The supporting element for the Tronsole® type Z was cemented into the 26 cm landing back at the prefabricating plant. Accordingly, the Tronsole® type Z wall element was installed and type F fastened to the landings and stairs on site.

A 9-storey, 18,000m2, mixed use development at 150 Holborn in the centre of London. It incorporates retail on the ground floor, offices above and 13 apartments in an adjacent block. Architect Perkins & Will specified URSA’s Walltec 32B slab in critical areas of the new build structure.URSA has supplied 1000m2 of URSA Walltec 32B slab as part of the multi million pound development in London. The mixed use scheme replaces a 1980s office block and feature a café, exhibition and reception space, atrium and roof pavilion with rooftop gardens. The overall building height was limited in order to maintain views of the nearby St Paul’s Cathedral.  The new building aims to offer a healthy work place with natural daylight being a key design feature. As a result the design also incorporates measures to minimise solar gains. Additionally the scheme aims to achieve a LEED ‘Platinum’ rating, BREEAM rating of ‘Excellent’ and Fitwel certification. URSA products assisting here with BS EN ISO 9001 and BS EN ISO 14001 certification along with a BRE Green Guide rating of ‘A+’.Ian Claydon, Technical Manager at URSA commented: “We worked closely with Perkins & Will in developing the specification for those areas of the external walls incorporating URSA Walltec 32B. Including options for the type of insulation to be used and U-value calculations. A particularly critical requirement was for the insulation to be non-combustible, Euroclass A1”.

The developer of an apartment conversion scheme in the Pennine hills village of Diggle near Oldham wanted to achieve superior sound reduction standards in the walls and floors and go beyond the minimum requirements set out by the Building Regulations.The Old Mill House project involved transforming a Victorian industrial building into several residential dwellings. The project’s design needed to comply with the requirements of Approved Document E, which sets out minimum standards in England and Wales for airborne and impact sound transmission between dwellings where there is a Material Change of Use.However, to deliver the highest quality living accommodation to potential buyers, the developer insisted that the acoustic specification not only met the minimum standards but went beyond them.To achieve their goals for the floors and walls, they approached Hush Acoustics for assistance in developing the specifications and providing the required products.Given the unique nature of the properties being created, the acoustic design for the flooring had to be compatible with underfloor heating and more unusual floor finishes such as stone tiling.The specification developed by Hush Acoustics for the separating floors beneath the floorcoverings featured a plywood timber deck, below which was the underfloor heating system and 8mm Hush FFR resilient underlay.For the ceiling side, Hush recommended standard acoustic insulation for use within the timber joists, two layers of 15mm Fireline plasterboard attached to the underside of the joists, the Hush MF Ceiling System to allow Hush Slab 100 to be fitted in the void created, finished with a layer of 15mm Soundbloc plasterboard.For the separating walls, two specifications were developed according to the types of walls. In areas where there was an existing masonry wall, a wall lining consisting of independent stud work, Hush Slab insulation and Soundbloc plasterboard was developed. In other areas of the scheme, a twin timber stud wall is recommended, again featuring Hush Slab insulation and Soundbloc plasterboard.As part of the process, the Hush Acoustics team undertook many site visits and guided the design and build process to ensure the correct installation was followed, and pre-completion testing was also arranged.The solutions developed and provided by Hush Acoustics fully met the developer’s goals to go beyond Approved Document E’s compliance standards according to the pre-completion tests.

OverviewThe BP2 office building was constructed on reclaimed land at the eastern gateway to the Canary Wharf estate and comprises 14 stories above ground, plus three basement levels. The building’s design places a strong emphasis on energy-efficient performance, so this was an important criterion in the selection of ventilators.OverviewThe BP2 office building was constructed on reclaimed land at the eastern gateway to the Canary Wharf estate and comprises 14 stories above ground, plus three basement levels. The building’s design places strong emphasis on energy efficient performance, so this was an important criterion in the selection of ventilators.Project BackgroundAir Design Systems Ltd provided a full design and build package for the client.

FOAMGLAS® READY BOARD T4+Architects: Pollard Thomas Edwards ArchitectsConstruction: 2010 - 2012Application: Façade: FOAMGLAS® Slab W+F, 150 mm thick, adhesive fixed;Metal Pitched Roof: FOAMGLAS® READY BOARD T4+, 200 mm thick, adhesive fixedCladding: KME, Tecu BronzeFor the renovation of the façade and the pitched metal roof, FOAMGLAS® was chosen for its resistance to water and for its excellent long-term thermal performance: combined with FOAMGLAS®, the metal roof and façade can last well over 200 years.The grade II listed 120 year old Granary building and the Malthouse are among the oldest buildings within the East London district of Barking and Dagenham. In 2009 the redevelopment master plan was prepared by Schmidt Hammer Lassen Architects. Design for the Granary and Malthouse was carried out by Pollard Thomas Edwards Architects whom certainly achieved the client’s key requirements for sustainability, and energy efficiency.Steve Drury, Rooff development director commented: "At an early stage FOAMGLAS® was specified for its environmental qualities and long term reliability. It is impervious to water and water-vapour and it actually provided an element of exterior weatherproofing as the building works progressed: the interior works could commence whist the metal façade was still being installed. FOAMGLAS® insulation, with its unique cladding fixing system, kept thermal bridging to a minimum; the resulting U-value performance exceeds Building Regulations by more than 25%.With time, the KME Tecu Bronze exterior will take on a natural patina. The metal exterior has a potential lifetime of well over 200 years, hence it’s very important to use the right insulation with a proven long term thermal performance.With FOAMGLAS® thermal ageing does not take place. It is the ideal insulation to be combined with roof and façade materials such as KME Tecu Bronze.For the pitched roof FOAMGLAS® READY BOARD T4+ was bonded and sealed to the timber board structure with PC®11 adhesive. Metal Plates type PC® SP 150/150 were inserted into the FOAMGLAS® READY BOARD. A 180 g/ m2 sanded bitumen membrane was torch applied onto the surface.

The Protec System was used to waterproof the domed green roof areas of this striking, sustainable house development which was featured on Chanel 4’s Grand Designs. With an ambitious vision and a tight budget, Robert and Milla Gaukroger set about transforming a dated 1980’s house overlooking Lake Windermere into a state-of-the-art, eco-conscious home. Since the house lay in beautiful hillside surroundings, in order to blend into this setting, the domed roofs of the house were to be covered with a wildflower meadow mix to provide a green roof construction.The SolutionThe Protec System was chosen as a waterproofing membrane for the roofs as it is ideally suited for green roof applications. Lightweight, flexible and highly durable, the system can easily accommodate structural expansion movements and is tough enough to resist root penetration. The Protec system was applied to over 350m2 of domed roof to provide a long-lasting waterproofing membrane.The key reasons why Eastleigh chose Protec are the same reasons that has seen it become one of the fastest growing cold-applied liquid roofing systems in both the new build and refurbishment markets. Combined with the timber cladding to the verticals of the building, the finished aesthetics of the development blended seamlessly with the surrounding areas.A warm roof build-up that can be made waterproof at multiple stages:For larger projects the Protec system can be made temporarily waterproof at two stages prior to the application of the full waterproofing system. The first stage is upon installation of the sealed, aluminium-faced vapour barrier.The second phase follows the reinforcing of the foil-faced insulation board joints with Protec resin and taping mat. This enables a much more controlled approach to the installation with a greatly reduced chance of rain causing disruption and damage during the works.Highly flexible membrane:Regardless of the size of the roof, Protec forms a homegenous membrane, without a single joint or seam and without the need for any expansion joints.RapidCure technology for quick installation:The application of Protec as a liquid, through to the curing process where a solid, tough membrane that can be walked over, takes only 30 – 60 minutes. This enables large sections of the roof to be fully completed in a short space of time.Installing the Roofing SystemsThe Protec System provided waterproofing to all flat roof areas as well as the extensive parapet wall sections. The roof areas were made up of two designs: the Protec Warm Roof System (approx 7,500m2) and Protec applied to concrete as part of an inverted roof design (approx 1,000m2).The roof installation was carried out with a planned, phased approach that was synchronised to the wider construction schedule. For the warm roof areas, the first stage was to fill the troughs of the structural metal roof deck with acoustic insulation infills that will dampen external noise within the leisure centre. Next, the crowns of the deck were primed ready to receive the self-adhesive vapour barrier.The use of a high-performance aluminium vapour barrier not only eliminates the risk of condensation within the roof, but also provides temporary waterproofing protection, which is extremely useful on larger works such as this.The Polyroof RES Insulation boards, which comprised of a two layer system totalling 170mm to achieve a U-Value of 0.14 W/m2K, were bonded using high-performance PU adhesive to the vapour barrier. Following the wind uplift calculations it was determined that mechanical fixings were not required for this application – making for an extremely rapid installation. As you can probably imagine, fixing through 170mm of insulation into the crowns of the metal deck can be a tricky and time-consuming task.A key advantage of using a tongue and groove insulation system is that the finished surface of the roof is smooth and level without any unsightly board steps that can also lead to standing water issues. The insulation board joints were sealed using Protec resin with Polymat Taping Mat 450 which, in addition to providing additional strength to the joints, also creates a temporarily waterproof layer.For the inverted roof sections, Protec was applied directly to the primed concrete/screed surface. The membrane was inspected by Polyroof Technical Services, signed off and then covered with inverted roof components. An interesting fact when using Protec in inverted roof situations is its incredible durability performance – as tested by the BBA, Protec “can provide an effective barrier to the transmission of liquid water and water vapour for the design life of the roof in which it is incorporated”.Monitoring and CompletionThroughout the duration of the contract, Polyroof Technical Services carried out regular site visits that were reported back to Interserve as part of Polyroof’s free-of-charge contract monitoring service. This enabled the client to keep up-to-date with the progress of the roof installation in detail and also provided peace of mind that the original specification was being closely followed and implemented.Polyroof worked closely with the Roofline Group during the installation, enabling the challenges were identified and solved in an efficient and coordinated manner – saving the client time and money.

WMOR Architects completely redesigned the ground floor to include a flexible living area to open into the garden. Accoya was chosen as the ideal material for the extension because of it aesthetic appearance as well as its ability to provide better insulation than other materials. & the owners wanted to use the most sustainable material they could. The Accoya extension which houses the show piece kitchen will be left to weather naturally and match the pale grey flooring. This was specifically designed so that in the summer, when the sliding door completely opens, the interior & exterior space will merge seamlessly.

The original waterproofing on the Maternity Hospital roof had exceeded its serviceable life and begun experiencing water ingress, requiring urgent remedial work. Bristol City Council wanted to optimise the roof area by installing a high quality, long lasting PV array that would contribute to its Solar City scheme that aims to provide one gigawatt of solar power to Bristol by 2020. The installation needed to cause minimal disruption to ongoing work at the hospital and insulation upgrades were necessary to ensure the roof achieved the required 0.25 U-Value.

The overall construction consists of 12 (mixed-use) buildings including the three primary towers which extend upwards over 54 storeys. When complete the towers will provide exception views over London, from the Thames and London Eye to the new American Embassy. In order, to protect the façade elements and ensuring the protection of the building against driving rain and moisture preventing future corrosion, insulation deterioration and mould growth at the same time it increases the building energy efficiency and minimizes the condensation risk, Effisus Breather FR-B Membrane were applied.

The 760,000 sq ft development will bring the Old War Office back into use, creating a world class 5-star hotel and 85 apartments. Works will include developing a six storey basement and constructing a three storey roof extension. The venue has been designed by UK-based EPR Architects, with the hotel interiors designed by New York-based designer Thierry Despont, and the residences by 1508 London. A1 Fire Rated Breather and Vapour FR Membranes were used to protect the insulation and building interior, maximizing its energy efficiency and value.

The building will be complete this year, in order to support the growing demand for skilled workers in the Manchester region, for the creative, digital and tech sector. The project was design by FCBStudios, embracing digital innovation and UX lab, film studios, green screens, edit suites, music and production studios, alongside a screening room and gallery space. Effisus Breather FR-B System was appiled to ensure the protection of the building against driving rain and moisture preventing future corrosion, insulation deterioration and mould growth at the same time it increases the building energy efficiency and minimizes the condensation risk.

The project was developed by Wilkinson Eyre Architects, and its glazed structure has created a new independent global hub for debate on sustainable urban living. Its design intends to both reflect the building´s context and at the same time having a degree of transparency to help connect the building with its surroundings. In this project was used insulated glass materials with varying levels of transparency, allowing spaces to be naturally lit whilst controlling solar gain. Effisus Ecofacade system was applied as an integrated solution to ensure water and air tightness of all facade elements connections.

The existing waterproofing had failed due to a previous poor installation, the result of which saturated the insulation below the exterior roofing. New high performance solutions were specified that included a range of IKO roofing waterproofing systems to protect both the flat and pitched roofing areas of the building. IKOslate, a robust and durable tile was specified for the pitched roof due to vandalism and the fragility of the current system, whereas a tapered scheme was required for the flat roofing - IKO Ultra Prevent alongside a cold applied liquid solution (IKO Polimar) for the more intricate details.

Located in the heart of Paris, La Samaritaine is one of the city’s most iconic department stores. When LVMH Group set about restoring the beautiful building, it faced a major challenge: how to marry the latest safety requirements with the building’s classic Art Nouveau and Art Deco design.Our solution was a passive fire protection coating system based on Hempacore One. Applied to structural steel, Hempacore One expands when exposed to high heat to insulate the steel beneath. In a fire, this can extend the steel’s load-bearing capacity for up to three hours.

Profile 22’s award winning optima suite of casement and Tilt and Turn Windows along with matching PVCU doors were specified in the refurbishment of two tower blocks in Walsall, West Midlands. The windows are designed to deliver increased insulation and weather protection, which makes them the perfect choice for high-rise, exposed locations. Increasing energy efficiency was one of the key drivers of the refurbishment. They are capable of achieving WER of A++ and U-values of 0.8 W/m2K. Indicative performance measures are 600Pa for air permeability, 600Pa for water tightness and 2400Pa for wind resistance.

Following the success of the Shoreline and Ocean hotels at Butlins’ Bognor Regis Resorts, the Butlins Wave Hotel is the newest addition, with the widest range of accommodation options.

The Royal Academy of Music in Regent’s Park, London underwent a renovation but needed to ensure three qualities were met, creating stunningly beautiful, acoustically brilliant, and inspiring spaces for staff and students.The 309-seat Susie Sainsbury Theatre was completely refurbished and created the new 100-seat rooftop Angela Burgess Recital Hall.The project marked one of the most significant building and renovation projects in the Academy’s near-200-year history.To help achieve these qualities ROCKWOOL HardRock® Multi-Fix (DD) insulation board was considered and installed.

Following years of neglect, the Grade II Listed Fellowship, Bellingham - London has undergone a huge transformation and in June 2019 reopened as the ‘Fellowship and Star’. Harking back to its history as a music and entertainment venue, it has a new cinema, theatre, concert space, pub; and is also home to charity ‘Lewisham Music’. To prevent the ingress of traffic noise from a busy thoroughfare outside and to prevent noise outbreak from the concerts and music lessons, 32 secondary glazed acoustically insulating units were manufactured and installed by Selectaglaze, to improve the performance of the original crittal windows.

In the development of the fenestration and curtain wall systems for Great Marlborough Street Reynaers worked closely with envelope contractors Baris Facades in order to develop no fewer than 6 bespoke cap profiles. One ensured that the insulated aluminium panels, which are a feature of the building, glazed flush with the curtain wall cap profiles. Another feature of Students Castle is the distinctive protruding box detail around the windows of the towers headed by aluminium louvre panels accommodated by bespoke capping. Further bespoke elements facilitate the omission of mullions on certain window positions, as part of the distinctive design.

Positioned at the end of Stansted Airport runway, is a brand-new College which opened its doors for the first time in September 2018. With just one runway serving all take off and landings, and the college’s location not far from the end of it, noise was a big concern. Selectaglaze helped provide a tailor-made solution with secondary glazing. It is the most effective method of acoustic insulation for windows in extremely noisy areas. Selectaglaze installed 32 units across the college with their Series 10 - 2 and 3 pane horizontal sliders and a Series 41 casement door.

Gateway 12 is multi-million pound industrial development on a c.16-acre site located three miles to the South West of Gloucester, adjacent to the A38 dual carriageway and just one mile form Junction 12 of the M5.For the main structure of the buildings Trisobuild® R32 was used for the roof and Trisobuild® C32 was installed vertically on the walls; Trisobuild® HR50 was used horizontally at the higher level for the soffits in Merlin Grey. The offices area wall elevations were constructed using Trimapanel® insulated panel system.

Silverlakes eco village in Dorset is a new build venture where the client wanted to achieve maximum sustainability.The houses, boat houses, garages and also communal areas such as the leisure centre required green roofs and M-Tray® was chosen due to its ease of transport and installation, and its square modular nature. Pre-grown, healthy sedum plants inside the plastic trays were laid onto the flat roofs across the village, providing an attractive dressing and improving storm water attenuation, thermal insulation and a magnet for wildlife.

This was a major refurbishment and landscaping project for an office development in the City of London. A podium deck had been re-waterproofed and the area landscaped, by contractor Scotscape, with a mixture of hard surfaces, grass lawns, planters and borders. Wallbarn has a very wide range of pedestals for a variety of applications. So we were able to supply exactly the right pad to best support the 6 x 2” joists the landscaping contractor needed to hold their decking boards. The timber joists were fixed into a frame and rigid insulation placed into the cavities between the beams.

Our technical team were invited to complete a roof survey and condition report of this residential project, where the existing roof area which was suffering from repeated leaks, failed repair attempts and significant standing water.ChallengesUpon inspection it was clear the roof covering had been recently renewed, but the workmanship, attention to details and drainage falls were sub-standard and no doubt contributory to the ongoing leaks and consequential ceiling damage to the areas below.Although the client preferred a robust torch-applied reinforced bitumen waterproofing system, our Safe2Torch assessment picked up some redundant roof plant, combustible cladding interfaces and complex penetrations which necessitated a localised flame free solution.Our team also carried out a level-survey to ascertain the existing falls, and what, if anything, could be done to alleviate the standing water without excessive cost.SolutionsOur comprehensive roof survey report included a dimensioned roof plan, identification of Safe2Torch areas/details, bespoke waterproofing designs for complex penetrations, and a thorough assessment of the existing roof make-up (via core samples) and drainage.Given the apparent age and good condition of half the roof area, it was left in-situ and overlaid with Hyranger single layer RBM system. Minor improvements to the drainage layout, via the introduction of a tapered insulation scheme central to the roof where the outlets where positioned, helped to significantly improve falls. Elsewhere, the rest of the existing roof covering and thermal insulation were stripped back to expose the original asphalt.The asphalt received a new air and vapour control layer before the same Hyranger system, including a mix of both flat board and tapered Hytherm ADH insulation, was installed to improve the falls and correct the thermal performance balance.A Safe2Torch abutment detail to existing cladding was identified early on in the Axter roof survey report as a fire safety hazard, so in accordance with our specification and recommendations, our accredited Axtershield Installer - N R A Roofing & Flooring Services Ltd - expertly installed a Hyranger Neo-Bitumen Flame Free membrane solution around a 900mm wide margin.The Axtershield Installer worked efficiently and to a very high standard to complete the project on budget whilst delivering an aesthetically pleasing and robust waterproofing solution.Systems in useHyranger®Neo-Bitumen® Flame Free

The Green Roofs Consultancy report looked to the provision of Green Bio diverse roof to address the need to encourage additional species. The ABG Green Bio diverse Roof System includes a mixture of plug planted sedum, cuttings and seeded annual and perennial wildflowers. ABG Roofdrain was used as a reservoir and drainage base layer to optimise water retention and prevent ponding. Special provisions were made to create hibernicula for local endangered species. The roof will benefit the building by providing additional insulation and reducing noise pollution.The roofs substrate filters out dust and pollutants helping improve the environment nearby

The purpose of this development is making the re-cladding of an existing building removing Aluminium Composite Material insulation and cement particle board and replacement with new 3mm aluminium cladding and associated works. The new building will include a mixed tenure unit of 138 one, two and three bed apartments. It’s design was developed by the PRP Architects. Its design was developed by the PRP Architects. In order to protect the façade building from moisture, driving rain and wind the solution Effisus A2 Fire Rated Breather FR System was applied, using an A1 Fire Rated Breather FR Membrane.

Conceived and developed by Knight Dragon, and designed by eight leading architects, this project collection of 16 unique buildings supports an ecosystem of 1,800 creatives, individual makers, ambitious start-ups, ground-breaking enterprises and industry leaders. Effisus partnered with London-based and award-winning Adam Khan Architects consulting on Façade Weatherproofing. The two buildings designed by Adam Khan are very different from each other, one a raw monolith of concrete and the other a lightweight building with an Op Art-inspired façade. Effisus Vapour FR membrane Class A1 was chosen to protect the insulation and building interior.
