GRG (Glass Reinforced Gypsum))
What is it:
GRG is a material composed of a thin layer of alpha crystalline gypsum and alternately arranged layers of glass fiber filaments. This fiber allows the creation of very light and thin pieces, as it provides the product with a high level of resistance to compressions and flexings. The plaster gypsum is neutral or low alkaline, which grants compatibility with the glass fibers.
Origins:
at the end of the Seventies a new material developped in England was exported to the US and Canada: nowadays, this product is known as Glass fiber Reinforced Gypsum. In a short period of time, American producers started to promote and sell products made of GRG. At the end of 1978 GRG products were distributed and sold all over North America.
Where it can be used:
it is suitable for the creation of boiserie, skirtings, furnishing accessories, columns, especially in crowded public areas. GRG may also be used in the interiors, whenever a strong and fire-resistant material is needed (for example, in casinos, hotels, theatres, private houses). It has various applications in the costruction industry, but GRG is also widely used in cruise ships, hotels, spas and thermal centres, and for restoration works.
Advantages:
GRG is a mineral therefore it doesn't burn. Moreover, thanks to the nature of gypsum, GRG shields other materials for a maximum of two hours. It is quite light compared to traditional stone or gypsum ornaments. Its installation is fast and easy and the material is highly flexible, which makes GRG suitable for complex geometries ceilings or for cladding decorations.
Surface finishing:
GRG is available in white colour and the surface can be finished by application of any kind of varnish.
