Alulite

Description

Alulite® Domestic is an efficient radiant barrier insulation product developed specifically for the residential and educational sectors. Manufactured using a sophisticated continuous laminating process, Alulite® consists of low-density polyethylene air cells laminated between reflective foil layers on both sides, creating an effective barrier against radiant heat transfer.

Designed for installation beneath roof sheeting and roof tiles, Alulite® helps keep buildings cooler during summer by reflecting radiant heat away from the structure while also providing moderate resistance to heat loss during winter through its trapped air-cell construction.

In addition to thermal benefits, Alulite® acts as an effective water vapour barrier and helps reduce dust penetration into roof spaces. Its lightweight design makes installation simple and safe, requiring no specialised protective equipment.

Alulite® complies with SANS 428 fire regulations, making it a reliable insulation solution for schools, residential properties, and housing projects.
