ALUBUBBLE 2017-09-29T09:56:08+00:00


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.

Technical Data

Recommended for warehouse and factory over purlin application.

Tested to SANS 428 and awarded a B/B1/2/H (USP) (No Sprinklers).

Africa Thermal Insulations (Pty) Ltd products are manufactured according to ISO 9001:2008 Quality Management System.

Level 6.

A leaking flat Roof could cause condensation and corrosion to occur which may damage the product and will negatively affect its thermal properties.

To ensure that ALUBUBBLE® remains in pristine condition, the rolls must be transported in a suitable, fully enclosed truck. They should also be stored under cover to protect them from direct sunlight and rain. Rolls should be stacked on their sides.
