Alucushion® / Bubblefoil®
Alucushion® / Bubblefoil® FR (Fire retardant grade) is manufactured by a continuous lamination process of low density polyethylene and aluminium foil with sealed bubbles of air between the two outer laminates. The thousands of individually celled air bubbles created during the manufacturing process, form a column of immobilised dry air, effectively countering heat loss through convection and conduction. Add to this the low emissivity and high reflectivity of the aluminium foil surface, and it’s advantages as a heat transfer barrier become obvious. Alucushion® / Bubblefoil® FR (fire retardant grade) is the cost effective solution for most roof insulation applications.
