Glass Fibre Reinforced Gypsum (GFRG)

The new material concept was found in England in 1977: the product is now known as Glass Fiber Reinforced Gypsum, also Referred to as Fiberglass Reinforced Gypsum (GFRG) and Glass Reinforced Gypsum (GRG).

  • The material is made of gypsum plaster reinforced with glass fibers to produce a thin, lightweight, yet strong material. GRG is used where it is not subject to Dampness. Moreover, it can be used wherever a light, strong, and fire-retardant material is required. GRC comes in many shapes and products moldings, ceilings, columns, light coves, bas-relief, domes, capitals, fireplace surrounds, medallions, and custom shapes.
MODIFIED GRG
  • Gypsum can be reinforced with common E-glass fibers. Unlike cement, gypsum is not high in alkaline and does not generate lime while it is curing. Therefore, Gypsum has an advantage over unmodified cement matrixes. However, gypsum has poor weather resistance abilities, and is only suitable for indoor applications. Research programs have shown that Modified GRG has good mechanical and physical properties, which enables the material to be used for a wide range of applications. The material shows improved weather resistance that makes it possible to use the product outdoors. The material has been used successfully for manufacturing architectural Cladding panels, decorative ornamentation, and column covers, flowerpots.
