Gyprock Glasroc F

Fire protection with Gyprock Glasroc F

CSR Gyprock launched Glasroc F, a paperless gypsum board offering high performance fire protection for structural steel columns and beams. Reinforced with glass fibre and providing up to 120 minutes fire protection, Glasroc F is installed in a single, joint-less layer.

Delivered in partnership with plasterboard specialist Saint-Gobain and forming part of Gyprock’s International Alliance program, Glasroc F meets the needs of the Australian building industry.

Gyprock Glasroc F is a 30 millimetre thick paperless, square-edged gypsum board. It features glass fibre tissue immediately below the surface on both sides, and its core is reinforced with glass fibre rovings and paper pulp.

The board’s gypsum content contains nearly 21 per cent chemically combined water or crystallisation, and about 79 per cent calcium sulphate. When Glasroc F is exposed to fire, the chemically combined water is released in the form of water vapour.

Once the gypsum layer is completely calcified, the calcium sulphate acts as an insulating layer for as long as it remains intact. The process of calcination helps protect from damage when used to encase structural steel columns and beams.
