Products Features

(1)Non-flammability: Yihe-board is non-flammable and conforms to the national grade A standard (GB8624 Grade A) with excellent fire resistance property. It is Flame Resistant to Combustion at 800 and Remains Flameless at 1200 .In case of fire, the board will not burn and not give off poisonous smoke.
(2)Heat insulating: Owing to low heat conductivity,the product has good performances on keeping warm and heat insulation.
(3)Water-proofing and moistureproof: The product is allowed to long-term expose to moist environment but still very stable. The board still keeps Intact after being soaked in water for one month ,the phenomenon of swelling and out of shape will not happen.It has good adjusting mechanics like woods. Even it is used on wash house.
(4)Problem-free: Yihe board provides good insulation against bugs, fungus and corrosion. It can last for a long-time and will not corrode.
(5)Noise-proofing: Yihe board provides good insulation against noise. 95mm soundproof wall made of YIHE board can reach the soundproof standard of 123mm wall made of four layer of 12mm gypsum board, which is equal to 150mm common solid brick wall.

(6)High-Strength and Lightweight: Owing to the density is not high,the board is light weight, in this case, it can decrease weight of building greatly.At the same time, the material is high-stength and not easy to be damaged.

(7)Easiness to construct: The construction process does not require complicated tools but just the ones used in regular wood construction. Our board can be fixed on light steel frame with self-attachable screws or a glue gun to nail the bolts into the wooden frame. It may be Scored and Snapped ,Cut ,Trimmed ,Drilled or Shapped using ordinary Power or Hand Tools.
(8)Good for environment: Yihe board is 100% free of Asbestos Fiber and will not cause any harm to human body or the environment.
(9) Be able to lined easily: The board can be lined with granite,tile,wallpaper etc. The board surface is very Smooth on one side and Sand-Textured Rough on the other.
The Smooth side is suitable for Painting or Wallpapering with No Further Preparation,and the Rough side is suitable for Application of Ceramic Tile.
