Features of rock wool board:
Bright yellow in color
Light ,burliness, elastics and useful product
Effective sound absorption
Good insulation properties: its thermal conductivity less than 0.042W/(MK)
Low moisture rate and good hydrophobic
Environmental protection and no-injuring to human body
With excellent rebound property, when reachs the destination, will rebound almost to the original level in 24 hours after been unpacked.
Application of rock wool:Heat preservation for steel structure buildingHeat insulation for wall and roof of house to save energyFor indoor partition wall,Train compartment Special specification can be made upon on request.
Widely used for heat insulation and sound absorption industrial workshops, warehouse, public facilities, exhibition centers, shopping malls, and a variety of indoor playgrouns, sports stadiums and etc.
