Fiber cement board is made from wood fiber, quartz, cement, lime and other materials. It is a new type environmental construction material with 100% asbestos-free.
As to the characteristics for this product, there are light weight, high strength, good fireproofing and thermal insulation. Its fire-resistant limit always can reaches 2H above, if on fire, it will not give off smoke. Besides, this product is damp-proof, shockproof and hardly to be damaged by insects and rodents. In addition, it is easily to be constructed and its useful life always can reaches over 50 years. Meanwhile, it also has good sound absorption that can insulates against sounds over 40dB.
Use fiber cement board for constructions can reduce the building load and increase the floor usable areas.
