Plaster glass (GRG) is a material that is sturdy, long-lasting, and lightweight. It is ideal for use in the construction of architectural curves and angles, as well as contemporary "sculpture."
The material is composed of extremely fine casting plaster that has been reinforced with strands of continuous filament glass fiber and metal channels that have been galvanized. The fact that the material cannot be burned and has an infinite rating for the rate at which flames spread across its surface both contribute to the product's high level of safety.
