The TremLock® T-238 from Tremco Roofing and Building Maintenance is a symmetrical, two piece mechanically seamed standing seam roof panel with a 2 3/8" seam height consisting of a metal panel and seam cap that can be installed on a broad range of substrate applications including open-framing. The seam is in a 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.

With its symmetrical shape, clips can be pre-installed to cut down on labor time.  Coupled with the ability to repair or replace individual panels, this helps make the TremLock T-238 system lower cost and longer lasting than competitive metal roofing systems.

With a minimum slope requirement of only ½:12, the TremLock T-238 metal roofing system is ideal for retrofitting, re-roofing, and new construction.  To learn more specifically about how well the TremLock T-238 system works in retrofit applications, click here.  Our spec data sheet is available here and our installation guide can be downloaded here.
