Gulf-O-Flex® NBREngineered insulation, Middle East proven.
The benchmark for thermal and acoustic pipe insulation in HVAC and MEP applications across the Middle East.
Gulf-O-Flex® NBR 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. Its closed-cell structure is a self-sustaining, passive solution to energy efficiency requiring no active maintenance to deliver consistent thermal and acoustic performance.
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.
