The Sky Tunnel is here
Sola Skylight has developed a ventilation and natural light pipe system called the Sky Tunnel Power Ventilation Kit. The company says it offers the same natural light properties as the company's existing Sky Tunnel roof-to-ceiling range with the added benefit that it reduces condensation and odours. The system has a polycarbonate dome and extractor device which are fitted to a single metal soaker tray. The kit also uses a reflective and flexible polyester tube which pipes the natural light to the diffuser in the ceiling below while a second flexible tube can be connected to an extractor fan. The maker says the ventilation system is suitable for installation in bathrooms, lavatories, shower-rooms and utility spaces.
Safer bituminous roofs
Marley Waterproofing has brought out a cold-applied, fully bonded bituminous membrane roofing application called Life Cycle Membrane System 20. According to Marley it provides a safer working area for installers because there is no need to use bitumen boilers or gas torches, and because the membrane includes pre-formed details, installers can spend less time on the roof. The system is suitable for both cold and warm roof applications.
Woolly thinking from DuPont
DuPont has launched a breathable roofing membrane called Tyvek Vapermax, said to reproduce the structures and quality of wool to create enhanced insulation. The company says the fibres of the membrane never get wet because their hygroscopic core structure accelerates moisture transfer, and the sheaths of Tyvek Vapermax repels water. This means that the risks of interstitial condensation are reduced to the lowest level. The product can be used directly in contact with the insulation in warm roofs or in cold non-ventilated roofs.
Plastic transparent tiles
Suntile has launched a transparent tile, also called Suntile, that is made from recycled or recyclable plastic and clear robust UV-stabilised polycarbonate. Suntile says it can replace an existing roof tile without the need to fit lead flashing, cut joists or carry out any other structural work. It is available for pitched and flat roofs.
Radio controlled roof windows
Velux has launched an electrically operated roof window range called Integra that incorporates remote radio operation to enable users to have complete control over every roof window, blind and shutter from anywhere in a building. Velux says the system is easy to fit because all electrical components are pre-installed. The roof window has a motor concealed behind the sash section for a smooth and quiet operation and a rain sensor which automatically closes the window when it rains.
Large concrete tiles
Sandtoft has launched two large-format clay tiles called Olympus and Cassius. Sandtoft claims that Olympus is the largest and most cost-effective clay tile ever produced in the UK, and that Cassius is a natural and economical alternative to slate because it combines the aesthetic qualities of slate with the low cost of a large-format concrete interlocking tile.
Movers and shakers
- Alfred McAlpine Slate has introduced a manufacturing process to produce up to 300,000 Welsh slate roofing tiles per week at its purpose-built £6m facility at Penrhyn Quarry in north Wales. The manufacturer says the process replaces traditional hand-split slate by using multiblade saws, which increases yield and reduces wastage.
- SFS Intec has published a revised and updated version of its pitched roofing and cladding fastening systems catalogue, which includes information about a wide range of fastening systems, illustrations of common applications and details of single, twin skin, standing seam, secret fix and composite panel systems.
- Lafarge has developed ViewMaster, a computer application that visualises the results of a re-roofing project carried out using its Redland range. The software, which is based on photographs of real buildings, applies all the visible roof details including options for the ridge and any hips, valleys or verges. Lafarge says the images are particularly suitable for consulting residents in preparation for social housing refurbishment. Another feature is the ability to add wall renders to get an idea of how roof colours contrast with the walls.
- Glidevale, a supplier of roofing and ventilation products, has issued a research paper called The Importance of Roofing Underlays in Reducing the Risk of Damage Caused by Wind Uplift. This provides guidance about the issue of wind uplift on roofing underlays. The company says the paper deals with the role of roofing underlays, certification phraseology and wind uplift performance.
- Marley Eternit has launched a technical manual called Pure Roofing which provides information about the design, detailing and specification of tiles and slates for pitched roofs. The 182-page guide includes a CD ROM containing more than 2500 CAD details of tiles, slates and accessories to assist specifiers with design plans. Pure Roofing also contains details of environmental guidelines and advice on best practice and how to assess the sustainability of buildings. Marley Eternit has also issued a 60-page guide to its fibre cement profiled sheeting systems. The maker says that the guide has advice on products, design detailing, site preparation and model specification
