Glass Fiber Reinforced Gypsum(GRG)OR(GFRG)

Glass Fiber Reinforced Gypsum is a mixture of gypsum, Portland cement, and sand. It consists mainly of ultra-fine alpha plaster and glass fiber reinforcement. The GRG can then be cast into virtually any shape, and any size. The material is extremely lightweight, and strong, as it requires little to no additional structural support.

Why use GRG

  • Glass Fiber Reinforced Gypsum, also known as GRG, or GFRG, is a building material most commonly used in domes, columns, mouldings and ceilings. Because of its low cost, versatility, strength, and lightweight, GRG makes for an ideal building material.
  • Glass Fiber Reinforced Gypsum can be used in both residential and commercial buildings. Most extensively used in malls, airports, and office developments, Glass Fiber Reinforced Gypsum offers a clean, professional and seamless finish that is often a first choice for creating complex shapes. GRG can be manipulated into any design and texture, making it extremely versatile.
  • GRG also offers a huge selection of stunning finish options. The smooth, quality surface provides an ideal base for paint and other finishes. Limestone, marble, and alabaster are some examples of the finishes available. It can also be finished with any interior paint, such as water/oil based, stain and gold-leaf.
  • Glass Fiber Reinforced Gypsum also offers many more unique advantages. GRG is 100% non-combustible and totally flame resistant. Not only will it not burn, but also shield the material behind it from the heat and flames for a significant period of time.
  • GRG is also painting-grade finish, crack and shrink resistant, and non-toxic. Installing GRG is relatively quick and easy. It should, however, be noted that GRG should be used in interior applications only and should not be exposed to rain, or be used in fountains and pools.
  • Glass Fiber Reinforced Gypsum (GRG or GFRG) is a highly versatile and durable material that can be used in a wide range of architectural applications at a fraction of a price of other building materials. Whatever the job, GRG can do it quickly, easily, economically and beautifully.
