NBR Foam with Alu-Clad Facing

Gulf-O-Flex® AlucladEngineered insulation, Middle East proven.

Best-selling closed-cell NBR insulation with factory-applied Alu-Clad facing - a passive, self-sustaining solution for outdoor and mechanical systems.

Gulf-O-Flex® Aluclad 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. The insulation is finished with a factory-applied Alu-Clad facing, making it ready for external applications - the facing protects the foam from UV rays and minor mechanical damage.

Overview

Built around three decades of regional know-how.

Gulf-O-Flex® Aluclad 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. The insulation is finished with a factory-applied Alu-Clad facing, making it ready for external applications - the facing protects the foam from UV rays and minor mechanical damage.

A passive solution to energy efficiency, Aluclad needs no active maintenance to deliver consistent thermal performance. Its lightweight, flexible structure resists heavy stress without breakage, while exceptional resistance to moisture vapor, mold, and mildew ensures long lifespan, reduced downtime, and continuing efficiency across mechanical and outdoor systems.
