Foreverboard drywall improves the benefits and performance of magnesium oxide in the production of a board that can be used in the building industry for other purposes besides drywall and exterior sheathing. As an environmentally friendly building material, the board has strength and resistance due to very strong bonds between magnesium and oxygen atoms that form the magnesium oxide molecules (chemical symbol MgO). The product is a proprietary magnesium oxide concrete board that has dramatically reduced the vulnerabilty of drywall to water, fire, insects, mold and mildew. Besides being extremely durable it is environmentally friendly and leaves no carbon footprint.
