Aluminum foil fiberglass cloth consists of 18u aluminum foil, 8×8 mesh/cm glass cloth as well as heat-activated polyethylene on its back. A premium grade Heat-Sealing aluminum.-glass cloth facing, tough and durable. Suitable for in-line heating lamination insulation materials. No need applying extra adhesive. Good abrasion and corrosion resistance.

The Aluminum foil fiberglass cloth excellent on great heat reflection, vapor resistance due to foil facing. It is a typical Aluminum foil fiberglass fabric fabric for mineral wool (rockwool) lamination and facing. It can be produced according to heavier thickness glass cloth or special weave pattern glass cloth request.

APPLICATION:

The Aluminum foil fiberglass cloth are mainly used as facing for glass wool insulation, rockwool, mineral wool etc. Also aluminum foil facing is used under roof decking, under attic rafters, over existing attic thermal insulation, in floors, walls and crawl spaces, and in industrial and commercial buildings to block radiant heat coming into house through the roof during the summer and retain indoor heat generated during in winter.

FEATURES:

• Light weight
• High manufacturing accuracy
• High strength
• Small inertia resistance
• Strong heat dissipation ability
• Good visual effect
• High reflective insulation
• Heat resistant, water proof, stable at high temperature
• environmentally friendly, no smell and not-toxic
• Smooth and clear surface
