Sandwich Wall Board/ Insulation Wall Board

Sandwich board
Skin; Mgo board, OSB, cement board, stell
Core: Eps xps rockwool pu
1. Light weight:

Its density is only 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-proofness & Damp-proofness

It consists of medium density fiber cement flat board, which has very good water proof and damp proof property. Therefore, there is no worry about bulking, efflorescence, deformation, degeneration of strength due to moisture absorption. It's applicable for wet areas like kitchens, bathrooms and basements.

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. Thermal Insulation & Heat Insulation

Nowadays, the construction industry attaches great importance to energy-saving property of buildings. Ionic strip-type wall panel is made of pure natural vermiculite, quartz flour of high purity, inorganic fibre and plant fiber, through a curing process with steam of high temperature and high pressure. In addition, the internal alveolate structure also contributes to its remarkable thermal insulation & heat insulation property.

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, like A/C; 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.
