This premium 4x8ft glass-reinforced fiber gypsum board features a high-density non-combustible gypsum core encased in durable cellulose fibers and embedded with continuous glass fiber mesh. Designed for commercial and industrial applications, the 1220x2440mm panel meets ASTM C1396 standards for fire resistance and structural integrity. With a nominal thickness range of 9.5mm to 15mm, it combines lightweight handling (approx. 10.2kg/m² at 12mm) with exceptional load-bearing capacity.
Ideal for commercial building walls, hospitals, and data centers requiring fire-rated partitions. The GFRG board is also widely used in HVAC duct enclosures and elevator shaft linings due to its moisture-proof properties.
