Skywall Translucent Systems, part of Terrell, Texas-based The Vistawall Group, has introduced SmoothSeal details for skylight sills and purlins.

According to a company press release, SmoothSeal is for use on the company's advanced translucent skylights (ATS) where the rafter bay spacing is five feet or less on center and the slope is 30 degrees or less. The new product, which uses a special backer rod along with a silicone sealant, was designed to provide a clean look for skylights. In addition, because SmoothSeal eliminates the use of a purlin cap, there is no ponding of water above the cap.
