Rock wool blanket has good thermal insulation performance, convenient construction and installation, significant energy-saving effect, and high cost performance; rock wool blanket is a kind of thermal insulation material with low thermal conductivity. It is suitable for large and medium-diameter pipelines; medium and small storage tanks and equipment with small curved surfaces or irregular surfaces, building air-conditioning pipe insulation and anti-dew, and sound absorption and insulation of walls.
Rock wool blanket products use basalt as the raw material, which has good non-combustibility, and the melting point is above 1000℃. It is particularly effective in heat insulation and fire prevention, reducing or absorbing noise.
Non-flammable / Fire prevention / Pest control
Asbestos free / Stable chemical properties
No effect on human body and environment / Easy to handle and transport / Low maintenance cost
Rock wool blankets are suitable for heat preservation, heat insulation, sound insulation and noise reduction of large pipelines, containers, storage tanks, boilers, and conveying pipelines. The rock wool blanket has a metal wire mesh with a single-sided reinforcement mesh, and its firm binding force ensures that the rock wool will not be torn or damaged.
Affixed with aluminum foil can better meet the needs of heat insulation and water vapor barrier for HVAC ducts, heating and cooling water pipes, and for building heat insulation. Make the room warm in winter and cool in summer, and comfortable in four seasons
