Rockwool Blankets (Rolls)

Description

ROCKAL Duct Warp 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 products. ROCKAL Rockwool Rolls comply with ASTM C-553-92 Type VII, E-84, E-119.

Application

Thermal & Acoustic insulation of rectangular and round, heating, ventilation, air conditioning duct work temperature range 10°C to 600°C. Used in commercial, industrial, and residential buildings specially for small areas. Helps saving energy up to 80%, controlling heat loss or gain and condensation during system operations.

Facing

ROCKAL Duct Wrap are faced with reflective vapor barrier material (Reinforced Aluminum Foil FSK).
FSK, FRK,Unfaced, Wiremesh, BGT, BGF, Kraft Paper.
