A lightweight cladding system that uses natural clay tiles, walkable large-span glass roofing and a slate tiled system for conservatory roofs are among this week’s featured products
Lightweight cladding system
European Building Materials has launched Vidar, a lightweight cladding system using natural clay tiles. The system is recyclable and complies with theBS EN 1304:2013 standard. Vidar tiles can be used for both facades and roofs, and allows solar panels to be integrated flush with the facade or roof elements. The cladding system weighs 40kg/m2 and is assembled in 3m lengths. It has been tested to a height of 25m and resists winds up to 40m/s. The tiles are available in seven colours.European Building Materials
Movers and Makers
The Trussed Rafter Association and Paramount Safety Solutions have released a new guide on safe installation of roof trusses on new homes of masonry construction. The guide is aimed to help reduce on-site risks to builders working at height. It discusses the three main sources of injuries and fatalities, describes the specific construction skills of installing roof trusses, and advises readers on preparing and installing roof trusses safely. How to Safely Install Roof Trusses is available as a free download from the website at: tra.org.uk
The online version of the Robust Details handbook has been updated this year for the fifth time. It includes the introduction of a new masonry wall, a new room-in-the-roof system and the introduction of a generic spandrel panel. The update also contains additional options on the resilient layer for E-FC-15 and expanded polystyrene added as an alternative insulation layer to E-WT-2 and E-FT-1 flanking walls. The up-to-date version of the Robust Details handbook can be downloaded for free from: www.robustdetails.com
Natural slate manufacturer Cupa Pizarras celebrates 125 years this year. The firm produces its slate in its own quarries and warehouses, and every tile can be traced back to source by a unique barcode, ensuring 100% traceability. Cupa Pizarras slates have been used in projects such as Tokyo Central railway station, the Edificio Metrópolis in Madrid and Tobermory Church on the Isle of Mull in Scotland.
St George’s Hotel in Llandudno, Wales, utilised Polyroof products for its roof development project, which involved the creation of five balconied bedrooms. The project included removing the roof from the 163-year-old building, which sits on the town’s seafront, and raising it by 2m to accommodate the five new rooms. Polyroof’s 185 System was chosen because the membrane could withstand rainfall, and was also strong enough to cope with footfall in the balcony areas. Light Battleship Grey coloured 185 was laid directly to 18mm Metsa Spruce II/III plywood, together with a warm roof system in both roof and balcony areas.
Roofing underlays from DuPont were specified for a slate roof extension in the historic Jamaica Inn. The roof needed to match the heritage architecture of the inn’s 1750s stone structure. The project used 225m2 of DuPont Tyvek Supro, a naturally vapour-open, windproof and watertight building membrane, as the underlay. The membrane meets all the requirements of Building Regulations Parts L and C and standard BS 5534:2014, in all zones, altitudes and conditions.
Standing-seam roofing and cladding system
The SSR2 standing-seam roofing and cladding system from Catnic provided a bespoke design solution for a porch detail installed across 150 homes at a housing development for Barratt Homes and David Wilson Homes. The self-supporting canopy is made of a 40mm x 40mm steel box support, which is bolted to the window unit and supports gallow brackets. This has been wrapped in 18mm plyboard with the Catnic SSR2 fitted on to it. The system meets the legislation for load-bearing for wind speed in accordance with BS EN 1991-4, and weather tightness in accordance with BS 5534 Parts 1 and 2.
Cold liquid-applied waterproofing membrane
Kemper System has provided its Kemperol V210 cold liquid-applied waterproofing membrane for the upgrade development at the University of Huddersfield. The product was chosen because the project required a practical, durable solution and the specifier had previous experience using it. Green roofs were specified for three sections of the building, in total covering an area of 4,500m2. The Kemperol V210 waterproofing membrane was installed first, followed by the insulation, the blue roof drainage reservoir and then the growing medium.
Walkable large-span glass roof
Walkable large-span glass roofing from Wrightstyle has been specified for the renovation of 270,000ft2 of office space at the Financial Times newspaper. The structurally glazed rooflight has been completed using Wrightstyle’s SR60140-2 and SR60140-4 profiles for the rafters and purlins. It underwent a TN67 test, where weights are dropped on to the glass to ensure the safety of anyone walking on it.
Flush fixed rooflights
Glazing Vision’s Flushglaze fixed rooflights were used to convert a heritage-listed farm barn into a contemporary home. The ceiling was 8m high and had an exposed wooden gable structure. The rooflights were precision-engineered and installed into the existing roof apertures. The Glazing Vision Flushglaze fixed rooflights are tested and certified by the British Board of Agrément to ensure they provide the required thermal performance, weather resistance and structural integrity.
Tiled conservatory roof system
Eurocell has expanded its Equinox tiled conservatory roof system range with the addition of SlateSkin.The new system allows the roof pitch to be set anywhere from 5° to 35° and, it meets the requirements of BS 476 Part 3:2004 for the external fire performance of roofs. The SlateSkin sheets are pre-cut to size and numbered for easy identification to save time during installation.
EOS Rooflights has expanded its triple-glazed modular rooflight systems to meet demand for larger rooflights and ventilation. The company now offers an upgraded triple-glazed version, with all the same benefits as the original model but with a system U-value of just 0.65W/m2k. Both models, the original and the upgraded one, feature a 32mm double-glazed unit comprising an outer, 6mm clear toughened pane, a 6mm krypton-filled cavity, a 4mm premium toughened pane, a 8mm krypton-filled cavity and an internal 8.76mm laminated premium pane.
Handmade clay tiles
Canterbury handmade clay plain tiles from Marley Eternit were used to create a roof with a rustic aesthetic for a new-build historic-style cottage in the Denham village conservation area in Buckinghamshire. The building had to follow strict planning guidelines for roof height and use of materials due to the number of listed buildings along the same road. The tiles were chosen as they blended in with the existing heritage look of the village. In addition, they complemented the copper gutters and downpipes, also needed to fit in with planning requirements.
