Product Description
Product Overview
Stonewool insulation board laminated with aluminum foil (FSK) provides exceptional thermal insulation, fire resistance, sound absorption, and condensation prevention for commercial and industrial applications.
Material Composition
Manufactured from natural rocks (basalt and dolomite) melted at high temperatures, stonewool forms long fibrous strands that are bonded into slabs, blocks, and other forms. The material is chemically and biologically inert, free from plant pathogens.
Applications
- Power generation facilities and exhaust flues
- Metallurgical, oil refining, and chemical industries
- Boilers, heat exchangers, reactors, and storage tanks
- Furnaces, ovens, autoclaves, and kilns
- Air-conditioning ductwork and refrigeration equipment
- Building construction for walls, roofs, and elevator wells
