CSB Siding plank , it is a kind of calcium silicate board with cedar pattern , medium density and low water absorption .The purpose of Siding plank is for climate-resistance, waterproof, wind loading resistance, UV proof, exterior wall leaking protection and good thermal insulation. It can be used for exterior wall cladding and façade of various high-class and high rise civil building which demand in artistic effect. 1. Durable. More than 60% of the composition is same as granite, more than 20% same as marble.2. High strength. The lowest strength (in parallel direction) is ≥14Mpa while the highest strength ( in cross direction) is ≥16Mpa which meets the national standard of typhoon-resistance.3. Light weight and low water absorption.Then density is ≥1.25 g/cm3. The water absorption is less than 35%. It can be used in new buildings for there will be no need to take additional load for them. Its light weight settles the problems of the renovation in the facade of old buliging and the leaking from the facade. It won’t affect its original construction. 4. Incombustible material. Meet the standard of GB 8624- 1997 grade A and ISO-1182 which is the guarantee of the fire proof.5. Good at impact resistance. It can be used as the base board in the shops, hotels, schools, entertainment places and hospitals.6. Outstanding thermal insulation and keeping warm capability. Siding plank has the capability in aeration, balancing the wind pressure, keeping the function of the system with warmth and thermal insulation, making the loss and expense of air-conditioner and warm gas in the building decreased.7. Low moisture and water absorbing. It can be used in outdoor wet area.8. Inorganic material.It’s fireproof, anti fungus and mould proof are good for the user’s health.10. Good quality and competitive price. Compared to other boards (real non-asbestos calcium silicate board) from international marker, it is much worthy.
