Double-Lok
|
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. This panel design provides a high degree of weathertightness and has been tested by independent laboratories in accordance with ASTM E283 and E331 (for air infiltration, water penetration, and wind uplift).
