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.
