Alububble

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.

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.

Alububble® will not propagate fire and does not present a fire hazard when installed in a building.
