Product Description

Product Overview

Stonewool insulation board laminated with aluminum foil (FSK) provides superior fire resistance, thermal insulation, energy conservation, condensation prevention, and sound absorption for commercial and industrial applications.

Material Composition

Stonewool (mineral wool) is manufactured from natural rocks (basalt and dolomite) melted at high temperatures and formed into fibrous strands. This chemically and biologically inert material offers excellent thermal and acoustic insulation properties.

Applications

Ideal for power generation, metallurgical, oil refining, and chemical industries. Suitable for exhaust flues, boilers, heat exchangers, storage tanks, furnaces, air-conditioning ductwork, and building applications including walls, roofs, and elevator wells.
