Gulf-O-Flex® AluglassEngineered insulation, Middle East proven.
Best-selling rubber insulation finished with a factory-applied aluminum glass cloth facing - a passive, self-sustaining solution for energy efficiency.
Gulf-O-Flex® Aluglass is a Flexible Elastomeric Foam made of Nitrile Butadiene Rubber (NBR), available in thicknesses from 6mm to 50mm in both sheet (with or without self-adhesive) and tube forms, finished with a factory-applied Aluglass facing. The closed-cell structure delivers consistent thermal insulation performance with no need for active maintenance - a passive solution to energy efficiency.
Engineered for extreme climates.
Four pillars define every Gulf-O-Flex® roll, sheet and tube - measured, certified and serialised.
Built around three decades of regional know-how.
Gulf-O-Flex® Aluglass is a Flexible Elastomeric Foam made of Nitrile Butadiene Rubber (NBR), available in thicknesses from 6mm to 50mm in both sheet (with or without self-adhesive) and tube forms, finished with a factory-applied Aluglass facing. The closed-cell structure delivers consistent thermal insulation performance with no need for active maintenance - a passive solution to energy efficiency.
Its resistance to moisture vapor, mold, and mildew growth ensures applications enjoy a long lifespan, less downtime, and continuing efficiency. Lightweight, highly flexible, and able to undergo heavy stress without breakage - ideal for pipes, bends, ducts, tanks, vessels, and flat surfaces. CFC and HCFC free with zero ODP. FM Approved, UL Listed, and EPD Verified.
