TarraLight Underlay felt 1 × 10 m – Self-adhesive underlay felt for roofs

TarraLight is a high-quality bitumen-based underlay felt (aluskermi) with a self-adhesive edge, designed for secure and fast installation of the roof’s underlayer. The product is used as an underlay covering in multilayer roofing and serves as a temporary waterproofing layer during construction.
