Self-Adhesive Weatherstrip is designed to be applied to the “stop” perimeter of a frame to prevent energy loss, reduce noise and dust infiltration. It will not crack or craze in cold or heat. Self-adhesive application makes installation easy and requires only scissors or a utility knife to cut to size. Tested in accordance with ASTM E-283 and listed by Warnock Hersey for use on labeled openings up to 90 minutes.
