Calcuim  silicate board

1.The highest heat insulator2.Stiff and non- shattering3.Low heat conductivity

1 Fire resistant: It is Flame Resistant to Combustion at 800 and Remains Flameless at 1000 . Non-Flammability: Grade A

2 Weather resistant: Resistant to Deformation in Wet, Hot and Dry Conditions. Can be used at -40 degree Out of Shape Rate in the Condition of Wet or Dry is 0.26%.

3 Water and Damp Proof: 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 will NOT Disintegrate when Immersed in Water Or Exposed to Freeze/Thaw Cycles for Prolonged Periods of Time.

4 Bug & Mildew free: After tests under ASTM G-21, this board has been found to be Non-Nutrient to Mold ,Fungus Growth or Insect Life.

5 Insulation: After Inspection by the National Center for Quality Supervision and Testing of Fire Building Materials (NFTC) it has been found that the Superior Sound Insulation Factor of a Wall built from the board ranges between 44dB and 47 Db. In addition to being a great Sound insulator ,This board benefits from having a Low Thermal Conductivity of 0.216 W/Mk which makes it a superior Heat Insulator.

6 Environmentally Friendly: This Environmentally Friendly board is manufactured from a unique blend of Mineral Components, and does NOT contain any Toxic ingredients ,Asbestoes, Formaldehyde or Ammonia
