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.

Thermal and acoustic insulation and fire
barrier used in commercial, industrial,
residential buildings. Mainly used for flat
surfaces like rectangular tanks, building
facades, studios, theaters, gypsum board
portioning, ceiling, building facades and
curtain walls and flooring insulation.
ROCKAL Rockwool Boards can be non-Faced or faced with reflective vapor barrier material (Reinforced Aluminum Foil FSK) or Kraft Paper, fiber glass tissue BGT or BGF.
ROCKAL Rockwool fibers products are classified as Non-Combustible materials and follow the fire safety rating achievements:
-Class 1 Surface spread of flame in accordance to BS 476
-Class 0 in accordance to BS 476
-Class A1 in accordance to European standards
-Surface burning characteristics in accordance to ASTM E-84
-Fire Spread Index: Less than 10
-Smoke Developed Index: Less than 25
