Soundproof Boards | Sound Block Board
Magnesium oxide boards are a factory-made sound block board products. They can be used in many applications, including walls and ceiling linings. MgO soundproof boards are also used for structural purposes, such as for wall support, and for semi-structural purposes, such as the bottom of the floor.
Magnesium oxide soundproof boards are similar to gypsum board, but with several improved properties, such as fire resistance, weatherability, strength, mildew resistance, flexibility, adhesion and so on.
MgO sound deadening board can be used for construction with a variety of thickness and sheet size. There is a “hard” sound when your knuckles, something like cement fibreboard. China has the world’s largest magnesium oxide deposit, enough to supplement the world for hundreds of years.

How are the MgO Soundproof Boards different?
MgO alone has been tested to 1200 °C without burning or flame out.
MgO is of no interested to insects and termites.
The MgO soundproof board does not absorb water, so the superheated steam does not “blow” the product under fire conditions like standard building bricks.
MgO soundproof boards for walls are fully fireproof. In the case of commercial uncontrolled fire, they will not burn.
MgO is not decomposed in water and is therefore ideal for areas prone to water
MgO sheet insulation helps protect the internal device from internal combustion
They can be used to make damping soundproof panels
MgO board is 8 to 10 times stronger than ordinary gypsum board, adiabatic not cold.
