Gulf-O-Flex® NBR
Gulf-O-Flex® NBR is a premium NBR rubber pipe insulation — a flexible elastomeric foam insulation made of Nitrile Butadiene Rubber (NBR), available in thicknesses from 6mm to 50mm in both sheet (with or without self-adhesive) and tube forms. This closed-cell rubber pipe insulation is a self-sustaining, passive solution to energy efficiency requiring no active maintenance to deliver consistent thermal and acoustic performance.
EN 14304 certified and fire rated rubber insulation with outstanding resistance to moisture vapor, mold, and mildew growth. Gulf-O-Flex® NBR ensures long service life, minimal downtime, and continuing efficiency across HVAC duct insulation, chilled water pipe insulation, district cooling, hot & cold water plumbing, refrigeration, and industrial applications. CFC and HCFC free with zero ODP — FM Approved pipe insulation, UL Listed, and EPD Verified.
Built around three decades of regional know-how.
