Glass Fiber Reinforced Gypsum (GRG)
A new concept of material was brought from England to the United States and Canada in 1977: a product now known as Glass Fiber Reinforced Gypsum, also referred to as Fiberglass Reinforced Gypsum (FRG) and Glass Reinforced Gypsum (GRG). This included gypsum plaster reinforced with glass fibers to produce a thin, lightweight, yet strong material.
Before long, North American manufacturers began promoting and selling products produced with GFRG. By late 1978, GRG jobs were being sold and installed in North America. Today, STATION is developing many of the techniques and technology used in modern GRG architecture.
Fabrication Process
GRG is primarily composed of two raw materials: high density alpha-based gypsum and glass fiber reinforcement. The gypsum plaster should be neutral or of low alkalinity to ensure its compatibility with "E" glass fibers. Additives commonly used within the plaster industry are acceptable provided they are used in accordance with the gypsum manufacturer's strict recommendations.
Applications
GRG is strictly for use where it is not subject to dampness. (Do not use where it is openly exposed to rain or for fountains, pools or wet locations). However, GRG can be used perfectly wherever a light, strong, and fire-retardant material is required inside hotels, theaters, residential spaces, and commercial lobbies.

Why Choose GRG?
Flame Resistant
GRG is a mineral and will not burn. In addition, the nature of gypsum acts like a thermal regulator when exposed to flame. GRG not only will not burn, but it also protects the materials behind it from the heat of the flame for up to two hours.
Easy Installation
GRG is relatively light in weight compared to traditional stone or solid plaster ornaments. Due to its reduced load, its transportation and on-site installation are quick and relatively easy.
Unmatched Selection
With our advanced molding and CNC technologies, GRG can be cast to virtually any shape, profile, or complex geometry the architect desires.
Versatile Finish
GRG is typically available in a pristine white color and is designed to be easily finished and coated with virtually any interior architectural paint.
