Rockwool Boards (Slabs) - Rockal | Rockal Rockwool Boards (Slabs) - Rockal

Rockal

ROCKAL Rockwool Boards are composed of mineral rock fibers, processed from volcanic basaltic rocks, Fibers are bonded together with a thermosetting binder which gives the flexibility & resilience to the product. ROCKAL Boards are especially rigid than other ROCKAL Rockwool products and comply with ASTM C-612.
