ROCK WOOL INSULATION

Rockwool Slab

Rockwool Slabs are semi rigid and rigid boards manufactured from stable stone fiber bonded with thermosetting resin binder. It can resist temperature up to 750°C. It is lightweight, strong, malleable, easy to handle and cut to suit intricate shapes.

Rockwool Slabs are available unfaced or faced with Glass reinforced Aluminum Foil, Kraft paper laminated facing, and Black Fiber Glass Tissue. They provide superior thermal, acoustic, and fire protection for industrial, commercial, and residential applications.

Non-Combustible Up to 750°C Thermal & Acoustic Semi-Rigid / Rigid
