12.5mm Glasroc F MultiBoard is a high‑performance, fire‑resistant gypsum board reinforced with glass fibre and is designed for specialist fire protection systems, offering enhanced stability, moisture tolerance and reliability in demanding environments such as fire‑rated partitions, encasements, ductwork protection, and structural steel protection. Glasroc F Multiboard uses a non‑combustible gypsum core strengthened with glass fibre and finished with a smooth white surface, making it suitable for both direct decoration and specialist fire protection assemblies. The board provides excellent fire resistance, dimensional stability, and moisture tolerance, performing reliably in areas where standard plasterboard would not be appropriate.
It is a key component in British Gypsum’s FireCase and GypLyner ENCASE systems, delivering certified fire protection for structural steel and service enclosures.
