Alucushion® FR (Fire-Retardant Industrial Bubble Foil)

View Spec Sheet (PDF)

Heavy-Duty Industrial Protection

Alucushion® FR is a high-performance, fire-retardant insulation membrane widely recognized as the cost-effective, heavy-duty standard for industrial warehouses, factories, and commercial roof applications. Manufactured through a specialized continuous lamination process, it seals a 4mm layer of low-density polyethylene air bubbles between high-reflectivity outer laminates. This design creates thousands of individual cells of immobilized dry air that aggressively counter heat transfer via conduction and convection, while the low-emissivity foil surface reflects massive amounts of radiant heat away from the building.

Strong, lightweight, and highly flexible, it boasts excellent tear resistance when stretched taut over purlins and straining wires. It serves a brilliant double purpose by acting as a 100% waterproof membrane, completely eliminating the need for an extra waterproofing layer underneath your roof sheeting. Furthermore, it is non-toxic, vermin-proof, and stable across extreme industrial temperature ranges from -20°C to +80°C.

Available Stock Variants

  • Single-Sided White (Code 2906): Our absolute best-seller. It combines a high-reflectivity foil top with an aesthetically pleasing, clean white polyethylene underside designed to boost interior light reflectance inside large facilities.
  • Double-Sided Foil (Code 1983): Features maximum thermal performance with metalized foil surfaces on both outer faces for intensive heat rejection.
  • Black Facing / Silver Reverse (Code 5050): Features a sleek black underside facing the interior with a silver foil backing, ideal for modern architectural aesthetics, dark-ceiling industrial designs, or specialized commercial spaces.

Problem-Solving Profile

  • Solves Extreme Factory Heat: Regulates massive indoor ambient temperatures to protect stock, machinery, and worker productivity.
  • Solves Fire Spread Concerns: Contains a highly advanced fire retardant tested to SANS 428 standard (SANS 10400 Part T compliance) and is certified not to cause fire to spread when used as an over-purlin roof insulation.
  • Solves Infiltration Issues: Functions as a permanent, non-deteriorating vapour, dust, and moisture barrier.
