About Carlisle's TPO Roofing System

Carlisle’s Sure-Weld TPO reinforced membrane is a premium, heat- weldable, single-ply thermoplastic polyolefin (TPO) sheet designed for new roof construction and re-roofing applications. Sure-Weld TPO membranes use advanced polymerization technology that combines the flexibility of ethylene-propylene (EP) rubber with the heat weldability of polypropylene.  All Sure-Weld TPO membranes include OctaGuard XT™, an industry-leading, state-of-the-art weathering package.  The physical properties of the membrane are enhanced by a strong polyester fabric that is encapsulated between the TPO-based top and bottom plies.  The combination of the fabric and TPO plies provides high breaking and tearing strength, as well as excellent puncture resistance. The relatively smooth surface of the membrane produces a total surface fusion weld that results in a consistent, watertight, monolithic roof assembly. The membrane is environmentally friendly and safe to install.

Sure-Weld High Slope (HS) membrane is formulated with additional flame retardant for higher-slope fire code approvals.
