Tremco Inc.
The TremLock® T-238 is designed to accommodate a retrofit or new construction on a range of substrate applications, including open-framing, with low slopes. Each panel is a symmetrical, two-piece mechanically seamed standing seam roof panel at 2-3/8-inch seam height consisting of a metal panel and seam cap. The seam is in the form of a T with two beads of continuous factory-applied sealant located on the seam cap. Once installed, this two-piece design provides a continuous, uninterrupted seal at the top of the seam.
