Polyester based styrene-butadiene-styrene (SBS) modified universal venting underlay.
A high performance, polyester-reinforced waterproofing material which is saturated and coated with high quality styrene-butadiene-styrene (SBS) modified bitumen. The upper side is finished with fine-grained sand, whilst the underside consists of specially engineered low melt bitumen stripes with sand in between, covered by thermofusible film to prevent the roll from sticking together. The stripe technology is designed to achieve partial bonding to the substrate and to allow any trapped vapour or moisture to dissipate in all directions, thus preventing blistering build up.
