Demand grows for JJ-Intelliroof
7 July 2012Output from James Jones & Sons’ Timber Systems Division in Forres has defied expectations in the first half of the year, largely as a result of the mild winter and encouraging levels of activity from national and regional housebuilders.
While the company's JJI-Joists are still used mainly in floors, they are increasingly being specified in walls and roofs, the latter through the company's internally developed, highly insulated, prefabricated roofing system: JJ-Intelliroof.
"We majored on this at Ecobuild and had a lot of interest, including from Continental visitors, something we're following up actively. This fits well with our current European presence, through Belgian partner VC Wood," said Timber Systems business development manager Mark Tilston.
A major UK housebuilder is now specifying JJ-Intelliroof in many of its house types, and other projects include a large public/private housing development in Yorkshire for the Rowntree Foundation, with roof spans of 12m; and a successful pilot project, called the Glasgow House, which is using building design and technology to address the critical issue of fuel poverty in Glasgow.
"Independently monitored energy-use results from the Glasgow House Project have been impressive," said Mr Tilston.
Demand for the JJ-Intelliroof is such that key fabricating partners for the system now include National Hickman and North Yorkshire Timber. Later this summer James Jones will report on its first Eurocode 5 roof project, for a large new school facility.
Another big first for the company has been the development of fire and preservative treatments for JJI-Joists, which were launched at this year's Ecobuild. They include a cost-effective preservative solution, acceptable for NHBC wall studs; a fire treatment solution, suitable for NHBC and UKTFA hazard class applications; and the inclusion of both treated and untreated JJI-Joists incorporating British, FSC-certified timber.
