Trimline StormStop Membrane
How Trimline StormStop® Membrane Works
Trimline® Shingle-Over Ridge Vent provides continuous ventilation while keeping out nature's worst elements. The ridge vent draws fresh air from soffit vents, exhausting hot, moist air through the ridge line to create a balanced ventilation system. In extreme weather conditions, damaging elements that could enter into the vent are blocked by the StormStop membrane in Rigid Roll® Plus and Rigid Vent PlusTM. StormStop is a revolutionary spun-bound material that keeps moisture out while allowing continuous airflow.
