Product Description
Fire Resistant Stonewool Insulation Blanket
Stonewool mineral products provide economical, lightweight thermal insulation manufactured from natural rocks (basalt and dolomite) melted at high temperatures. The resulting fibrous strands form slabs, blocks, blankets, pipe covers, and granulates that offer excellent thermal and acoustic insulation properties.
Applications
Designed for process temperature control, energy conservation, condensation prevention, and personnel protection across various industries:
- Power generation facilities
- Metallurgical and oil refining plants
- Chemical processing equipment
- Exhaust flues and hot gas ducts
- Boilers, heat exchangers, and reactors
- Storage tanks, furnaces, and ovens
- Air-conditioning ductwork and refrigeration systems
