Product Information

Double-Lok® panels are available in 12-inch, 18-inch and 24-inch widths. The Double-Lok® roof panel is a mechanically field-seamed, trapezoidal leg standing seam roof system. Double-Lok® requires a minimum slope of ¼:12 and is UL-90 and FM rated with Miami Dade County approvals. Double-Lok® Retrofit - If you're looking to upgrade your roof to a standing seam, then installing our Double-Lok® roof panel over your existing R panel roof without the need for sub-framing is an excellent choice. Installing a Double-Lok® trapezoidal standing seam over an existing R panel roof allows for an upgrade to a high performance, long-lasting roof while preserving the diaphragm and purlin stability provided by the existing R panel roof. There are two options to increase energy efficiency when using the Double-Lok® panel over an existing R panel. The first is adding two-inch unfaced fiberglass insulation between the existing R panel and the new Double-Lok® panel. The second is to vent the cavity between the old and new roofs by adding a vent strip at the eave to allow air intake and a vented ridge to provide for air exhaust. This method works well with roof slopes of 3:12 or greater. When choosing the Double-Lok® option, high clips are used to provide clearance between it and the major ribs of the existing R panel.
