RadiantGuard

Introduction

RadiantGuard is a flame-retardant commercial grade DS reflective Al foil insulation, made from 2 outer layers of highly reflective, pure aluminum foil and 1 layer natural Kraft paper. These layers are bonded together with F/R Glue and reinforced with 3-way fiberglass scrim.

RadiantGuard is ideally used as sarking and insulation material under roofs, in walls behind cladding or under timber floors for residential and commercial buildings. Combined use with glasswool / rockwool / mineral wool / foam insulation, it will be an excellent vapor barrier for air-conditioning ducts, pipes and vessels.

Because RadiantGuard sarking has a foil facing on both sides, it will provide benefit by reflecting heat for both summer and winter conditions (compared to single sided foils which only reflect heat in one direction).

The use of our RadiantGuardl sarking rather than traditional single sided foil sarking materials will mean you get much better summer performance of your building system
