Glass Fiber Reinforced Gypsum (GFRG) Panel is a composite consisting of alpha gypsum cement and water, reinforced with glass fibers – an ideal choice as an economical, lightweight, and durable replacement for traditional plaster.
Glass Fiber Reinforced Gypsum (GFRG) board is a building material that consists of gypsum plaster, water, and glass fibers. The glass fibers are added to the gypsum plaster mixture to improve the strength and durability of the material. GFRG boards are known for their lightweight, high strength-to-weight ratio, and fire-resistant properties.
The manufacturing process of GFRG boards involves spraying a mixture of gypsum plaster and water onto a continuous strand of glass fibers. The resulting product is a thin, strong, and lightweight panel that can be used for a variety of building applications. GFRG boards can be easily cut, drilled, and shaped on-site to fit specific design requirements.
GFRG panel possesses high flexural strength, shearing strength, compressive strength, and flexibility. It has a very high level of resistance to fire, water, heat, corrosion, rot, and termites. Concrete filled with vertical reinforcement rods improves it’s vertical and lateral load capacities. GFRG made buildings are resistant to fire, earthquakes, and cyclones.

Glass Fiber Reinforced Gypsum (GFRG or GRG) is the most economical Formglas material and is used in a range of architectural applications such as ceilings, column covers, decorative wall panels, domes, bulkheads, light coves, and more.
Grade and Type- GFRG panel may be supplied in any of the following three grades :
1) Class 1- Water Resistant grade – panels that may be used for external walls, in wet areas and/or as floor and wall formwork for concrete filling; 2) Class 2 – General grade -- panels that may be used structurally or non-structurally in dry areas. These panels are generally unsuitable for use as wall or floor formwork;
3) Class 3 – Partition grade – panels that may only be used as nonstructural internal partition walls in dry areas only.
