Wind-Lok® Soffit Panel system is a V-groove designed panel with the "hook, pull and fasten" interlock design. This design allows for one of the strongest panel interlocks on the market today and allows for quick, easy and permanent installations with concealed fasteners. Vented Wind-Lok™ Soffit Panels are lanced, which have open space for airflow at both sides of rectangular protrusions allowing for air circulation and reducing condensation. Typical applications for Wind-Lok™ are wide overhangs and ceilings on porches, breezeways, carports and patios.
