Magnesium Oxide Board is a kind of new green and fireproof building material that is used in place of traditional gypsum drywall as partition wall and ceiling covering material and sheathing. It could be used anywhere Gypsum boards or dry walls could be used, such as wall board, backer board, underlayment, siding etc.
1.Fireproof capability:the fireproof capability can be reached 2-3 hours, and it’s no combustion at 800ºC and no flame out at 1200ºC.
2.Sound and heat insulation:the Sound insulation will be more than 45db (depend on the structure), and it has a great performance on heat insulation
3.Shockproof:Fiberglass mesh inside the boards is designed to absorb shocks. It results in a shockproof and bend-proof board to increase durability.
4.Health concerns:MgO boards are Asbestos free,non toxicity and formaldehyde free.
5.Other advantages: Lighter,more flexible and stable than tradition sheeting systems;Time and material saving-dramatically reducitng construction costs;Environmentally friendly.
