"acoustic"

ChallengeThe St Vincent New Bridges’ project is run by St Vincent de Paul, a homeless hostel that supports people who need to have a place to live and that require help to develop their daily living skills. When the charity acquired the Grade II listed building, a major refurbishment plan was put into action, and St Vincent de Paul approached CRASH for help with materials and construction work.SolutionKnauf Insulation donated over 520m2 of 100mm Knauf Insulation Loft Roll 40 for the project, which was installed by Giraffe Building Services Ltd. The Glass Mineral Wool insulation product is extremely easy to handle and install, being lightweight and easily cut to size, benefiting the large project.BenefitsBy its nature, Knauf Insulation Loft Roll 40 is non-combustible and classified as Euroclass A1 to BS EN ISO 13501-1, a crucial requirement to any public building. Additionally, Knauf Insulation Loft Roll 40 has been manufactured with ECOSE® Technology which delivers superior environmental performance, as the binder technology is up to 70 per cent less energy intensive than traditional binders. The technology has been developed for Knauf Insulation’s Glass and Rock Mineral Wool products, enhancing their environmental credentials without affecting the thermal, acoustic or fire performance. Insulation products made with ECOSE® Technology contain no dye or artificial colours – the colour is completely natural.

The National Manufacturing Institute Scotland (NMIS) is a group of industry-led manufacturing R&D, innovation and skills facilities supported by a network of Partners across Scotland, all working together to transform the future of manufacturing and provide an innovative and multi-use hub that brings together Scotland’s brightest minds in industry, academia and the public sector.The design of the space focuses on collaboration, with a variety of private spaces specified to create areas for focused work and larger group meetings in turn.Planet, working through our northern contracting team, joined the project to provide our expertise in the design, manufacture and installation of a number of our glass partition screens and door solutions to meet the interior design by architects HLM.The standout contribution to this project was the use of Planet’s PURE20XL (38dB Rw) extended screens to produce glass meeting pods, expertly cantilevered to produce an eye-catching ‘floating’ effect. Access to the pods was provided by Planet’s high acoustic performance IsoPro glazed pivoting doors (42dB Rw). Our popular single-glazed PURE20 (38dB Rw) and double-glazed PURE100 (54dB Rw) frameless partitions were utilised for the fronts for many of the meeting rooms and laboratories — along with tech panels to house integrated room booking systems — while some extended PURE100XL screens was placed on the void edge of the digital seminar rooms.Finally, structural atrium glazing facilitated the passage of natural light deep into the internal space — perfect for the inspirational innovative environment NMIS aims to provide to its users.

Project: Ayr Academy, ScotlandProduct: OranitArchitect: BDP, GlasgowInstaller: Linear Projects, GlasgowAyr Academy, Scotland. BDP Architects (August 2017) Photos by Graeme DuncanSpecification:Oranit 7-501 Panels in Yellow PineQuantity:138m2  Oranit panels in PEFC Certified Yellow Pine were installed in rafts to the ceiling of the atrium space at the Ayr Academy campus which opened to students in September 2017.Shiluvit by Oranit was specified for it’s ease of design and installation as well as the stunning effect of slatted natural timber. The panels were installed in 12 rafts of 16 panels suspended at a slight angle to mirror the tilt and dimension of the true ceiling.The 6-year secondary school has state of the art classroom facilities for an engaging and high-tech learning experience as well as professional quality all-weather sports pitches as well as fitness, and dance suites which are available to the wider community. The school has followed suit from other local colleges and universities by including informal social and learning spaces in the atrium.The new campus is a huge step-forward from the previous historic 1880’s school and is inspiring enthusiasm and pride in all of it’s staff and students.In addition to the Oranit panels, LSA supplied Linear ribs to support the acoustics in the open plan main plaza of the school. The central drum clad in natural Oak ribs is a functional focal point of the space, housing a learning resource centre inside and hosting a computer classroom and social space on top.

ChallengesSinclair Watt were provided with a detailed brief to provide accommodation for a new main entrance and reception area, product display hall, meeting room suite, additional office space and customer service telephone hall and ancillary accommodation. By necessity these were required to be large spaces to accommodate large numbers of employees and visitors.The building had to achieve seven basic goals – to allow VELUX to be a good neighbour, to be simple and beautiful, to make arrival a good experience, to be a model of balanced daylight, natural ventilation, good indoor comfort and healthy materials, to apply a well-defined, high-quality structural concept, to obtain good sustainable standards with a minimum use of energy, to be visible and logical, and to create value and express the VELUX values.The ceiling systems had to meet the Class 1, aesthetic, fire and acoustic performance required for the 37,673 ft² two-storey building which features an engineered timber and steel structural frame. The project was the first time Zentia’s Ultima+ Finesse mineral tiles had been installed in Scotland.SolutionsSinclair Watt met the brief by incorporating a regular and prominent engineered timber and steel structural frame that provided a design with a clear distinction between the supporting structure of the building and the facades and roof. This was both to create clarity and logic in the design and to make it possible to replace or update the not-so-permanent parts of the building.The internal design incorporates a central street and atrium that acts as a meeting place as well as a general circulation area and allows the best use of natural sunlight and natural ventilation throughout the building. The building provides good indoor comfort and utilises healthy materials.The three key areas – energy efficiency, healthy indoor environment and renewable energy – constitute the basis of the new building. A fabric-first approach for the building was adopted with high insulation levels and low air permeability rates to reduce overall heat loss from the building. This combined with a natural ventilation and daylighting strategy, and the use of LED lighting and air source heat pumps as the main heating source, resulted in a highly energy efficient and sustainable building.Some 1,1,00 m² of the Zentia Prestige hA+ Tegular15 tiles were used in the ground floor offices and storerooms, while 100m² of the Finesse tiles were used in the restaurant, kitchen and toilets. The Ultima+ range features class-leading light reflectance of 87% and Euroclass A2-s1, d0 fire classification, the Tegular15 variant with Class A sound absorption and Finesse a fully concealed, fully painted edge detail.Architect Iain Mitchell said: “We specified the Zentia systems as they have a good product range, good suspension systems, with good product information and good technical backup. They met all the aesthetic, fire and acoustic performances.“Zentia shadow and transition trims were used so the Zentia ceilings tie in well with adjacent plasterboard walls and ceilings. The client is very happy with the ceiling installation and building as a whole.”Colin Burns, commercial director of specialist sub-contractor PFP, said: “We had some meetings with Zentia to talk through the detailing of the Finesse element and put it to the guys on site but apart from that, and some coordinating with services, it was very straightforward. It looks good as it always does and gives a nice bright finish. It was interesting to be the first installer of Finesse in Scotland.”

Middlewood Locks is a prestigious 25-acre mixed-use regeneration scheme of Salford’s canal district. The first development phase included the construction of Quarry, an eight-storey building combining ground floor commercial space, luxury apartments and an undercroft car park for residents. It was the insulation for this car park that threw up a challenge for sub-contractor Horbury Building Systems. A complex underdrawing method had been specified, comprising the installation of timber battens, non-combustible mineral wool insulation and a separate soffit insulation over the top. Installation would be extremely labour-intensive, so Horbury Building Systems consulted Knauf Insulation about whether it could provide an alternative that would meet the thermal performance and fire safety requirements, but also be easy to install. Knauf Insulation’s Technical Support Team reviewed the specification and recommended 185mm Rocksilk® Soffit Linerboard Extra to achieve the required 0.18 W/m2K U-value.  Rocksilk® Soffit Linerboard Extra is a Rock Mineral Wool insulation slab bonded to a 6mm off-white weather resistant facing board which provides a two-in-one aesthetic and thermal solution. It has a low thermal conductivity of just 0.034 W/mK and is designed for use as an insulated underlining solution in semi-exposed environments. The off-white cementitious particle board reflects light which makes it ideally suited for use in car parks. As well as thermal performance, Rocksilk® Soffit Linerboard Extra is non-combustible. It has the best possible Euroclass A1 reaction to fire classification, so it will not contribute to the development or spread of a fire should it occur. This is important because car parks can contain large quantities of a potential propellant – petrol. So the insulation will help to ensure the fire safety of the rest of the building.   Rocksilk® Soffit Linerboard Extra also has good sound absorption characteristics so it provides high levels of sound reduction. This reduces noise from the car park, minimising disruption for the people living and working in the premises above. As well as meeting the specification, Rocksilk® Soffit Linerboard Extra has been enhanced to add rigidity and is easy to install. The board is simply placed onto the concrete soffit and fixed into position with five drillscrews. This reduced the installation method from three separate phases to just one, saving Horbury Building Systems time and associated labour costs. Stephen Hampshire, Contracts Manager at Horbury Building Systems said: “We found the panels easy to install. Firstly, we marked and drilled the fixing points at bench level. Next, we held the panels in place to the underside of the concrete – although the panels are lightweight ‘this is a two-handed operation’ – then we drilled through and fixed.”  “We took care in lining the panels together when installing it against the soffit and with some minor tweaking up and down we got a nice flush finish.” Being able to align the panels exactly is not only important for ensuring a good finish. It also means that the slabs will butt tightly together, reducing unintended air gaps which can reduce thermal, fire safety and acoustic performance.  The insulation was supplied to the Middlewood Locks construction site by distributor Galaxy Insulation.  Thanks to Knauf Insulation’s Rocksilk® Soffit Linerboard Extra, the underlining of the car park at Middlewood Locks was easy to install, is aesthetically pleasing, and provides complete thermal, fire safety and acoustic performance.

The ChallengeBuilt in the 1960s, Warwick School’s Guy Nelson Hall was no longer fulfilling the needs of a modern, growing school. As well as not being too small to accommodate increasing student numbers during exams and large events, technical and IT infrastructure upgrades were needed to continue its use as a theatre space for the community.Located at the heart of the school’s site, the hall plays an important role in creating a good first impression for visitors to the school. Any redevelopment of the hall would also need to complement the existing buildings.The SolutionForterra’s County Multi Smooth, part of the Butterley range, a heritage brand that has been synonymous with brick making in the UK for over 150 years and is manufactured at Forterra’s Wilnecote brickworks. It was the ideal construction material for the project, enabling freedom of design with regard to form, scale and mass, while making a visual link with surrounding masonry.The brick gives a modern, uniform finish, which complements the smooth finish of the glass and concrete panels that also form part of the hall’s design.The BenefitsFollowing extensive redevelopment, that included the addition of an entrance foyer, kitchen, performance studios and a balcony area, Guy Nelson Hall has been transformed from school hall to a state-of-the-art 1,000 multi-use venue and concert hall.The clever design and materials used in the hall’s redevelopment have resulted in a building that incorporates modern design elements, such as its sweeping, curved façade, while blending perfectly with the existing vernacular. There has also been a significant improvement to the buildings acoustics.The project was completed in July 2016 ready for the new school intake in September that year.

Yoko Ono Lennon Centre is a unique teaching and performance building at the University of Liverpool. It has been designed by Liverpool School of Architecture graduates based at UK architecture practice Ellis Williams.The new facility includes The Tung Auditorium – a world class music performance space – together with two large lecture theatres, seminar rooms, café space, a public facing linear park and a new outdoor space for the University.With a floor area totalling around 6500m2 the building was planned around a careful understanding of the site and an innovative response to a challenging brief.PROJECT INFOThe lecture theatres were arranged vertically, which allowed for a much smaller building footprint – freeing up the site to deliver a linear public park alongside the main arterial route adjacent to the south elevation. This also allowed for large volume and height of Tung Auditorium to be placed adjacent to the teaching spaces, separated by the main atrium circulation space. Externally, the building’s form and materials relate to the robust architecture of some of Liverpool’s historic civic buildings and dockside architecture.The University of Liverpool was the original “red brick University” so the use of that material may seem obvious. The facing brick selected was Forterra’s Butterley Farmstead Antique.The bricks here are more than decorative however, they are a key part of the acoustic strategy and were selected for their density as well the colour and tone.The large inward looking spaces of the theatres by definition are without external windows and openings. The curved forms to the corners are used to both soften the impact of the mass (accentuated by the use of double stacked protruding bricks to catch the sun), and as a nod to the curves used in prominent corner buildings that can be seen across Liverpool.

PROJECT OVERVIEWThe project comprised the design, manufacture, supply and installation of a new 8000m2 footprint of a highly specified Packing Facility. The brief was to provide nine GMP Grade D packing cells, each of which required strict temperature, humidity and pressure control to enable primary packing of pharmaceuticals in a clean environment with no risk of contamination. Each of these Primary Packing cells connects to a common, secondary packing area. OUR SCOPE OF WORK To meet the project specification and environmental requirements, Norwood proposed our 100mm Mediline Partition. Following a rigorous selection process, our solution was a preferred option over four alternative systems. Working closely with the client’s team and the main contractor, we designed and developed bespoke solutions such as Flush Coving, Fire Rated Vision Panels, Bulkheads and Half Height partitioning. Cleanability has been ensured through the hygienic finish of the partition panels and, in particular, by incorporating recessed radiused coving at ceiling to wall joints providing a smooth clean finish throughout the room. Our innovative acoustic ceiling combines hygienic, wipeable, sound absorbing materials and cleanroom grade panels which not only reduce environmental noise levels but also provide cleanable airtight surfaces. Within the open plan secondary area, partial height glazed partitioning was employed. The facility was built with future adaptability in mind and the possibility of increasing the cleanrooms to Grade C, therefore the Norwood Flush Coving was utilised in the spinal corridor and primary cells. Supplying over 7000m2 of ceilings and 6000m2 of partitioning, this was one of Norwood’s largest projects, delivered to an extremely challenging programme. 

BACKGROUNDThrough the OJEU process, cfes were appointed by the Royal Free Hospital to design, build and maintain a Central Sterilisation Services Department (CSSD) on a brown field site in Enfield. The site incorporated 16 endoscopy reprocessors, 11 washer disinfectors, eight sterilisers, two large trolley washers and associated drying cabinets.BRIEFCfes required a modular hygienic partition system to create the process and support areas around the key equipment whilst achieving the HTM and fire rating requirements. In addition to the walls, the system also needed to support the distributed services and ceiling systems, as no load could be added to the building structure.SOLUTIONThe MIDDAS M100/M200 partition system was selected with associated structural framework, to meet all the hygienic requirements for the project. The M100/M200 severe duty framework was modulated around the key process equipment to provide the fixing locations for the beams. All beams were designed to support the distributed services with clear spans up to 10m, negating the need for secondary steel work. Hygienic ceiling tiles were suspended from the MIDDAS beams in all clean areas with acoustic ceiling tiles fitted in the support areas. The M100/M200 system benefits from full independent fire testing, where MIDDAS partitions have been tested with its proprietary flush glazing and integrated door sets as a system. This ensures the complete facility is fully compliant with the fire strategy for the project and is backed by our comprehensive test data. A further benefit of the system was that the structural framework allowed M&E services to be fitted before the finished partitions. The ceilings were then simply hung in place with factory formed cut outs to suit the service penetrations.

The ChallengeInstalled within the reception hall and circulation areas of the two towers, Pyroguard Protect, which was chosen by fire protection specialists, Pyrometal, has helped architect Ateliers Jean Nouvel achieve his ambitious vision, without compromising on safety.Following the successful testing, Pyroguard Protect was installed throughout DUO-1 and DUO-2.In the reception hall, Pyroguard Protect EI120 was fitted inside PYROTEK steel profiles to form full height glass partitions and in the circulation areas on each floor, around 690 square metres of E30 was used inside double-leaf doors with EI60 glass partitions.The same was also used in the corridor doors as a means of compartmentation, which connects various areas to the stairs and lift landings.The SolutionTours Duo rises on a former industrial site on the edge of the River Seine in the Paris Rive Gauche district and at 180 m, DUO-1 is set to be the third tallest building in the capital.The pair of towers, DUO-1 and DUO-2, which lean to form an impressive asymmetrical ‘V’, will house offices, retail spaces, restaurants, a hotel and a top floor panoramic bar.In the design of the mixed-use scheme, Ateliers Jean Nouvel was tasked to create high performing, aesthetically striking buildings and as such, decided to take a bioclimatic approach to reduce energy use and make the most of the outdoor weather conditions.Giving the best protection for people and property, Pyroguard Protect provides integrity and heat insulation for 30 to 180 minutes (EI classification).The solution also provides 1B1 impact classification without the need for additional counterpanes, high performing acoustic properties and peace of mind throughout the lifespan of the product due to its UV stability.

The remarkable 22 Bishopsgate Project stands as the second tallest building in the United Kingdom and Western Europe, showcasing its architectural prominence. On its 58th floor, an awe-inspiring viewing gallery offers breathtaking vistas. Perched even higher, on level 59, a discreetly hinted restaurant is poised to offer an unparalleled dining experience, with a renowned chef at the helm. Although the details remain a secret, the restaurant promises to be a highlight. Beyond its striking stature and exclusive amenities, the project's core objective revolved around enhancing the base build construction to optimize noise levels for the activities and events within the Viewing Gallery. Aiming to strike a balance, the project sought to both amplify the permissible noise levels for these events while curbing any potential noise breakthrough into adjacent spaces.In the dynamic context of 22 Bishopsgate, where concrete installation was unfeasible due to location and occupied lower floors, a visionary solution was sought. Over 1246m², the innovative Stravifloor Channel floating floor system was meticulously installed. In lieu of concrete, a bespoke approach utilizing high mass calcium sulphate boards was designed, ensuring both functionality and practicality. Addressing concerns about floor height, custom-designed bearings were engineered to maintain top-tier acoustic performance, with a mere 30 mm thickness.Despite a demanding timeline to unveil the viewing gallery, the project remained on track. Stravifloor Channel, with isolated steel battens, played a pivotal role. Galvanized steel channels provided robust support over isolation pads, while the optimized discrete supports allowed minimal contact points to the subfloor.

Verdo, Kew BridgeEcoWorld BrentfordCemfloor Level PlusA luxury development of apartments, shops, restaurants, parks and offices situated next to Brentford Football Club in West London.Cemfloor Level Plus was chosen for this project as the contractor required a screed that could be installed at low thicknesses. Cemfloor Level Plus was supplied by Capital Concrete and installed by Advance Screeding UK ltdClose to the River Thames, and next to Brentford football club in West London, Kew Bridge is a selection of beautiful new homes, as well as shops, cafes and restaurants. It is part of the wider Brentford regeneration project, and developed by EcoWorld.There are a total of 6 blocks on the site, and Cemfloor was the screed of choice for the main contractor.The main contractor had problems with the floor levels on site, so Cemfloor provided a thin screed system to work alongside the unique low profile UFH system; a castellated mat system installed onto Superfoil insulation. The UFH system was supplied by Compact Underfloor Heating. The complete floor build was only 45mm in depth and included acoustic insulation, thermal insulation, castellated UFHsystem, and Cemfloor Level Plus.Advanced Screeding installed Cemfloor Level Plus throughout the development. In total 800m3 of screed was easily pumped to height, over 11 floors without issue,providing an excellent, fast drying low profile floor, and saving significant time on the project.As Cemfloor Level Plus is a ready mixed solution it removed the need for any site mixing, material storage and material disposal from the site. Given the volume of screed required; if a self leveling compound product was used this would have equated to approx. 55,000 x 25kg bags of material having to be mixed on site.

Two renowned Alumasc brands, Harmer and Wade, were recently specified and installed for a new striking residential development in London.Newfoundland Tower, also known as “The Diamond Tower”, due to its unique diamond shape and diagonal structure, is a build-to-rent development in Canary Wharf, London. Harmer SML Cast Iron above ground, and Wade gulliesand linear drainagewere installed to provide an effective water management solution.The Harmer SML lightweight cast iron pipework system is dry-jointed, BBA & Kitemark certified, and has a proven track record in above-ground drainage. With its comprehensive range of fittings and accessories, Harmer SML is the ideal soil and waste system for above and below-ground drainage, including rainwater installations, and is fully compatible with other Harmer and Wade drainage products.“Harmer was chosen primarily for its longevity,” said Gary Zumeris - Area Sales Manager – Harmer SML, South. “It’s also easy to install and has excellent acoustic qualities. It’s a very quiet system, which is especially good in apartments or other high-density housing as you can’t hear fluids flowing down the pipes.“The Harmer system was also chosen for its fire-resistant properties, which is an important aspect, due to current legislation. Cast iron is highly specified in London currently, where most buildings incorporate cast iron for increased fire safety.”Harmer SML has the highest product reaction to fire classification possible, which is A1 for BS EN 13501-1, as well as a system fire classification of A2 for BS EN 13823 Single Burning Item A2, s1-d0.
