 Internal linings specialist British Gypsum has launched a new ceiling board lining that combines high levels of thermal insulation with 30 minutes fire resistance.
Developed in conjunction with a major housebuilder, the board is an extension of the company's Gyproc ThermaLine Super range, developed to satisfy the fire performance requirements for ceiling membranes in 'room-in-the-roof' constructions.
A laminate of 15mm Gyproc FireLine, a special fire-resistant plasterboard and 40mm high performance phenolic foam, the new 55mm board includes an integral vapour control layer prevent condensation in the roof construction.
It is fixed directly to the underside of joists using 90mm Gyproc Drywall screws.
