1. Prevent from static, fire.
2. 5 years warranty period.
3. 10-20 years normal use time.
4. Calcium sulfate core,steel plate

Structure: High density calcium sulphate core.The auxiliary materials are: natural gypsum, fiber, chemical additives, and some auxiliaries are deriving from domestic waste.

Features: 

1. Has a pretty good thermal barrier effect, permanent non-combustible solid. It would take 2 hours for 800°C flame intensity to pass from one side to another. .

2. Brilliant absorption effect. Performs well in Impact sound insulation measurements.

3. Be trimmed with conductive edges. Bottom is galvanized sheet. Safe, reliable, because the panel forms a network for electrostatic discharge.

4. Process of fabrication will produce neither pollution nor harm to environment. Could be 100% recycled after the normal life time and it will self-degradate when buried deeply. So it is a environmental-friendly product.
