A heavy-duty flexible joist tape that helps extend the life of decking substructures by preventing water penetration and protecting joist lumber from rot. Keeps water out by providing a superior seal around screws at the fastening site. Won’t bunch, bind, or tear during screw driving. The butyl adhesive provides an advanced, secure bond to joists that won’t peel off. This tape’s strong backing won’t tear easily, even when walking on or dragging boards across the joist. Use in all weather conditions; rated for use in temperatures from -70°F to 200°F.
