Adequate roof ventilation and uniform airflow are critical for the proper maintenance and longevity of metal roofs. Ultra-x breathable closure strips are engineered to mold around and completely seal against the panel profile. The form-fit removes any leak path into the ridge area due to a poor fitting closure, thus eliminating wind-driven rain problems.
