Glass Fiber Reinforced Gypsum

GRG (Glass-fiber Reinforced Gypsum) is a new type of decorative material fabricated by laminating molding in molds, with microcrystalline gypsum as the base material, blended with reinforcing glass fibers and special additives. Its primary component is gypsum. Reinforced with glass fibers, it achieves far higher strength than traditional gypsum boards, and features light weight, high formability and environmental friendliness.
Core Features
  • High Strength & LightweightFlexural strength reaches 20–25 MPa, and breaking load exceeds 1200 N (10 times that of standard gypsum boards). It is 60% lighter than conventional gypsum. The standard thickness of flat panels ranges only from 3.2 mm to 8.8 mm, with a weight of 4.9–9.8 kg per square metre, effectively reducing building loads.

  • Unlimited FormabilityCustomisable to any shape in accordance with design drawings, including single curved surfaces, double curved surfaces, relief sculptures and hollow-out structures, enabling complex artistic architectural expressions.

  • Environmental Regulation CapacityIts microporous structure absorbs and releases moisture to regulate indoor humidity and improve environmental comfort. It boasts excellent fire resistance as a Class A1 non-combustible material. In case of fire, it releases 15%–20% moisture by its own weight to lower fire temperature.

  • Durability & Environmental PerformanceThe dry-wet shrinkage rate is less than 0.01%. It resists deformation and cracking with a long service life. Free of harmful substances, it complies with China Class A decorative material standards and can be recycled.

  • Acoustic & Construction AdvantagesA 4 mm-thick panel achieves a sound insulation capacity of 23 dB at 500 Hz, suitable for acoustically sensitive spaces such as theatres and concert halls. Manufactured in factories and hoisted on site, it shortens the construction period and allows large-area seamless joint installation.
