Fiber CementBoard Raw Materials: Reinforced Fiber, Cement, Quartz Sand Thickness: 4-30mm Normal Size: 1200mmx2400mmx6..12..18, Density: about 1.30g/cm3 Non-combustible: GB8624 Class A (CNS6532) Thermal conductivity: <0.20w/mk Category: Pattern Ceiling Board, Basso-relievo Ceiling Board, Empaistic Ceiling Board, Sound-absorbing Ceiling Board Moisture Content: <10% Water Absorption: <60% Anti-freezy: No distorion after 25 repeated cycles of freezing and thawing Radioactivity: Conforming to GB6566-2001 Grade A Standtard Edges: Square / Beveled Color: White, Light grey, Light yellow, Sky blue, others as per customers requests Packing: BoxProducts 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. 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. (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.
