Physical properties of mgo boards :

1. Light weight

Its density is 750-800kg/m3, and the weight of 75mm thick wall panel is 60kg/m2, which is only 1/6 of that of brick walls, 1/2 of that of aerated concrete, and 1/7 of that of 120mm thick masonry wall with plastering on both sides.

2. Fire proofness

It can endure fire at 1000 degrees for over 4 hours, without producing any toxic gas. Its incombustibility meets A rating of the state standard.

3. Water-proof & Damp-proof

It is excellent in moisture-resistance. Dry bending strength is 15Mpa. Bending strength under absorbed moisture is 22Mpa.

4. Sound Insulation

It has outstanding sound absorption and insulation capacity. The sound insulation capacity of a 90mm thick board is 42dB, which is far higher than that of other masonry walls, and meet the national requirement of sound insulation for residential houses.

5. Heat Insulation

It has heat prevention material incorporated, it has great feature of heat prevention. Thermal resistance is 1.14m2k/w.

6. Better earthquake resistance and overall stability

Assembled into a whole structure, wall panels has an impact resistant capacity which is 1.5 times as high as that of normal masonry walls. The earthquake resistances is tens of times higher than normal masonry walls, meeting the requirement for buildings to resist earthquake of up to 8 degrees.

7. Easy installation

The wall panel can be grooved freely, nailed directly or embedded with expansion bolts to hang heavy things; The single-point hanging strength is over 45kg; In addition, the wall panel has a flat and smooth surface, which is compatible with tiles and wall paper as the finish.
