20mm Glasroc F Firecase - Fire‑Protection Board for Structural Steel - 2000mm x 1200mm

20mm Glasroc F FireCase is a non‑combustible, glass‑reinforced gypsum board designed specifically for structural steel fire protection within British Gypsum’s FireCase and GypLyner ENCASE systems. Glasroc F FireCase is manufactured from gypsum reinforced with glass fibre tissue, glass rovings, and paper pulp, with water‑repellent additives incorporated into the core. This produces a dense, robust and dimensionally stable board suitable for frameless steel encasement, ductwork protection, and semi‑exposed installations before the building envelope is complete. The board has a smooth white surface, accepts standard jointing and finishing systems, and can be cut and fixed using typical drywall tools.

Glasroc F FireCase is selected for projects requiring certified structural steel fire protection, non‑combustible performance, and high durability. Its proven reliability within British Gypsum’s FireCase systems makes it a standard choice for commercial, industrial and public‑sector buildings where fire safety and compliance are critical.
