1220x2440mm Durable Fiberglass Board 9mm Glass Fibre Reinforced Gypsum Board
Product Description
Glass Fiber Reinforced Gypsum (GFRG) board, also known as Fiberglass Reinforced Gypsum (FRG) board, is a type of construction material made by combining gypsum plaster with glass fibers. The glass fibers are embedded in the gypsum plaster to provide increased strength and durability, making it a popular choice for use in buildings, particularly in interior walls, ceilings, and partitions.
Product Features
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.

Product Appliction
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.
