Designed for use alongside Stoneleaf Sovereign underlay, the Stoneleaf Band is a premium single-sided adhesive tape engineered to seal vertical joints and overlaps seamlessly. Constructed from a highly vapour-permeable polypropylene membrane and a high-performance acrylic dispersion adhesive, it ensures the roof’s breathability remains completely continuous, even around repairs or penetrations. Fully UV-stabilised and weather-resistant, it delivers a durable, long-lasting seal in tough site conditions.
