Rockwool Boards (Slabs)

DESCRIPTION

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.

APPLICATION

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.

FACING

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.
