Alucushion/Alububble® is a superior performance radiant barrier material, simple to use and cost effective. This product is manufactured using a modern sophisticated continuous laminating process which consists of a layer of low density Polyethylene air cells laminated on both sides with aluminium foil or alternatively on one side with a white polyethylene layer which provides an aesthetically pleasing finish to the underside. Alucushoin/Alububble® uses the thermos principal of providing a reflective barrier along with adjacent air space to keep the building cool in summer and warm in winter. Alucushion/Alububble® will not propagate fire and does not present a fire hazard when installed in a building.
Alucushion® / Alububble® 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.
