Visitors to James Jones’ stand S1775 at Ecobuild will have an opportunity to see its panellised roofing system, the JJ-IntelliRoof in action. The stand will be built using the IntelliRoof, incorporating a solar panel and a cabrio Velux window. James Jones says that specifiers will be able to see at close hand just how effective the system is, and to appreciate why it is being used by leading national housebuilders. <br> <br> James Jones explains that the JJ-IntelliRoof is proving particularly popular in terms of speed and cost of erection and is now being produced in long spans up to 12m in hipped roofs and for a variety of non-standard roof solutions. <br> <br> Stand S1775 is also showcasing the JJI-Joist, which James Jones claims is the UK’s only home–produced, FSC certified i-joist. <br> <br> The company will use Ecobuild to launch the Fire &amp; Preservative Treated JJI– Joist, which offers solutions for NHBC and UKTFA hazard class applications.<br> <br>
