About the Double-Lok® Metal Roof System
Where Exceptional Durability & Energy Efficiency Intersect
Double-Lok® is perfect for those looking to upgrade to a standing seam roof system. And installation is a breeze. Double-Lok® panels install over your existing R panel roof without the need for sub-framing. In the end, you get a high performance, ultra-durable roof while preserving the diaphragm and purlin stability provided by the existing R panel roof. And to increase energy efficiency, you can either (1) add two-inch unfaced fiberglass insulation between the existing R panel and the new Double-Lok® panel or (2) 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. The latter method works well with roof slopes of 3:12 or greater.
