Carlisle Roofing

Sure-Weld TPO

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-Wel High Slope (HS) membrane is formulated with additional flame retardant for higher-slope fire code approvals. Sure-Wels EXTRA is 80 mils thick for significantly higher strength and weatherability. 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.

Features and Benefits

APEEL Protective Film can be left in place for up to 90 days without degrading due to its excellent heat and UV resistance.

• Outstanding puncture resistance
• Excellent fire resistant assemblies
• Environmentally friendly and stable formulation
• Excellent resistance to impact and low temperatures
• Excellent chemical resistance to acids, bases and restaurant exhaust emissions
• UL 2218 Class 4 Hail rating
• Exceptional resistance to heat, solar UV, ozone and oxidation
• Manufactured using a hot-melt extrusion process for complete scrim encapsulation
• 100% recyclable (see Carlisle’s Recyclability Statement)
• Enhanced with the OctaGuard XT weathering package
• APEEL Protective Film applicaiton guards the TPO membrane’s surface from scuffs and dirt accumulation during installation, improving the roof system’s appearance and long-term performance

Sure-Flex PVC

Carlisle’s Sure-Flex PVC is an advanced-forumal, heat-weldable PVC thermoplastic membrane that is designed for long-term weatherability and performance. The physical properties of the membrane are enhanced by a tenacious, weft-inserted polyester fabric that is encapsulated by thick PVC-based top and bottom plies. The smooth surface of the PVC membrane allows for a total-surface fusion and permanent weld, creating a consistent, watertight, monolithic roof assembly. PVC can be used in adhered and mechanically fastened systems. The gray-colored bottom ply provides a visual confirmation of a proper weld during the lap welding process.
