British gypsum has introduced a hybrid version of its award-winning GypWall Extreme partition system for applications where a separating structure requires performance beyond the current BS5234 maximum ‘Severe Duty’ rating, to one side only. The new Gypwall Extreme/Robust hybrid comprises a Gypframe metal stud core faced to one side with the company’s latest super impact resistant Glasroc Rigidur H high density fibre board, and to the reverse with 15mm Gyproc DuraLine board. The board will ensure that specifiers of education and healthcare buildings can economise safely and efficiently.

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.
