A1 grade fireproof board - WYR-105

fireproof board

Magnesium Oxide Board (or MgO Board) is a technologically advanced building material that offers superior performance in every category when compared to traditional wood, gypsum and cement based products. Magnesium Oxide Board is virtually impervious to fire, water, insects; does not feed mold or mildew; is non-toxic, non- flammable and non-combustible; is durable, maintains its dimensional stability-even when wet; and, has exceptional bonding surface. Magnesium Oxide Board is a mineral based green builder product. And it is homogeneous-no de-lamination.
