PRO-Tac Flashing and Joist Tape

A heavy duty, flexible, all weather flashing and joist tape to extend the life of decking substructures, with a strong superior seal that prevents water penetration and protects joist lumber from rot.

Superior Smooth Seal

Keep water out at the fastening site, with a strong seal that secures around screws and won’t bunch, bind, or tear during screw driving.

Heavy Duty Use

Unlike the competitor’s thin, difficult-to-handle tapes, this tape’s backing won’t tear easily, even when walking on or dragging boards across.

High Quality

The butyl adhesive provides an advanced, secure bond to joists, without the unpleasant odor of other asphalt-based tapes.

All Weather

Use in all weather conditions; rated for service temperatures from -70°F to 200°F .
