Radiant Barriers are a fundamental part of a modern tiled roof. Wind tunnel tests and practical experience have shown that the underlay performs an important function in preventing excessive pressure build-up inside the roof during wind gusting.
In addition, it provides a safeguard against possible rainwater penetration in extreme conditions and acts as a thermal barrier, thereby improving insulation that results in reduced energy costs. It also acts as a safeguard against dust penetration.
