First, the surface technology is different。Roof board: made of advanced high-tech technology, and the wall form a whole, natural color, can be processed according to needs. Exterior wall panel: Wall with aluminum or cement facade. Using environmental protection materials, no pollution, no radiation and pollution-free environmental protection building materials.

Two, different performance。Compared with other materials, the roof board has light weight, fire prevention, moisture-proof, heat insulation, corrosion resistance, impact resistance and other properties. It is a kind of fire-resistant building material, which can withstand the high temperature of more than 1000℃, will not burn after fire, and has the characteristics of thermal insulation, durability, easy cleaning, reusable.Exterior wall board is a new type of decorative material which is waterproof and moisture-proof. Its surface is made of multilayer composite, with waterproof, moisture-proof, mildew proof performance. At the same time, the surface has anti-ultraviolet function and anti-corrosion function.

Three, installation is different。Roof board does not need to do load-bearing wall, simple installation, can be directly pasted wall board, can also do ceiling. As long as the keel is fixed on the wall, there is no need to make holes in the wall or fixed, you can paste it directly, you can also use expansion bolts to fix, you can adjust the fixed spacing between the gap between the board and the wall is uniform, so that the wall is firm without cracking and other problems. Exterior wall board is a building decoration material formed by pasting board. The outer wall board is fixed on the wall, and the wooden keel is used to fix it, without the need for hole installation. The wallboard can be nailed to the wall, and you can paste latex paint or tile adhesive on the cement wall.
