2. Good effect of fire proof: Because of flame retardant material is adopted, the EPS sandwich panel is of good effect of fire proof. 

3. Good effect of heat insulation: Average thermal conductivity is less than 0.04w/m. K.

4. Light weight and long durability: the density is between 10-14Kg/sqm, which is in light weight with short construction period and low cost.

5. Excellent sound proof: The sound insulation is more than 30db, which can effectively reduce sound noise.


Rock wool sandwich panels are made by color filament fibers of rock wool in the core. They are profiled by automated continuous forming machine and adhesive bonded later.

It has the characteristics sound insulation and fire-proof, fast installation speed, durability, and beautiful appearance, etc. so it is widly used as roofing material for steel structure plant, gym, Supermatet ,commercial and civilian facilities.
