Product Introduction
Glass wool blanket is a lightweight and flexible thermal and acoustic insulation material supplied in rolls. It is manufactured from fine glass fibers bonded into a resilient blanket and can be supplied unfaced or faced with aluminum foil, kraft paper, or other protective facings. It is commonly used in roofs, walls, HVAC ducts, industrial equipment, and metal building insulation.
Features:
- Environmentally friendly.
- Energy-saving.
- Easy to cut, handle, and install.
- Fire performance: Grade A.
- No health hazards, asbestos-free.
- Outstanding thermal and acoustic insulation.
- Stable physical and chemical properties.
Applications:
- Thermal insulation, heat insulation, sound absorption, and noise reduction for building exterior walls.
- Insulation for industrial furnaces.
- Interlayer insulation for steel insulation boards.
- Noise reduction in generator rooms and pump rooms.
- Maintaining constant temperature in computer rooms and refrigerators.
