This board has a fireproof core essentially made of gypsum, reinforced with additional fibers that are resistant to high temperatures. They give the boards more strength and resistance against fires when used in previously evaluated assemblies. 

Covered on both sides with 100% recycled paper. The paper on its front side covers the entire length of the beveled edges of the board for greater strength and protection of the core. The edges are carefully ground in a square cut.
