Double-Lok^® Panel

Double-Lok^® Panels

Double-Lok^® is a standing seam roof system that attaches to sub-framing using a variety of concealed, interlocking clips that provide for minimum panel penetrations. Double-Lok panels can be used on new construction as well as retrofit on existing structures. With fewer exposed fasteners (by 80%) than traditional side lap panels, this panel design provides a high degree of weathertightness. Panel penetration is eliminated over the entire building envelope other than at the end laps and panel ends which are connected by a compression joint. The panels are factory notched at both ends with pre-punched holes, and the end laps feature a 16-gauge backup plate with pre-punched holes.
