Sure-Weld TPO membrane by Carlisle Coatings & Waterproofing -
100% recyclable

Sure-Weld is a heat weldable, single ply thermoplastic polyolefin (TPO) sheet membrane consisting of three layers. Sure-Weld is based on advanced polymerization technology that combines the durability and weatherability of ethylene-propylene (EP) rubber with the heat weldability of polypropylene.

The membrane is specifically formulated for long-term weather resistance without the use of either polymeric or liquid plasticizers (PVC Free). 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 provide Sure-Weld reinforced membranes with high breaking strength, tearing strength and puncture resistance. The relatively smooth surface of Sure-Weld membrane produces a total surface fusion weld that creates a consistent, watertight monolithic roof assembly.

Applications

• New roof construction exposed or ballasted.
• Green Roofs.
• Re-roofing applications.
• Balconies.
• Podiums.
• Plaza Decks.
• Planters.
• Below grade blinding slabs.

Installations
Sure-Weld TPO can be installed using any of the following methods;

• Mechanically fastened with insulation.
• Fully adhered with insulation - monolithic.
• Fully bonded to the substrate - monolithic.
• Loose laid and mechanically fastened.
• Loose laid and contact patch adhered.

Sure-Weld Features and Benefits

• Sure-Weld TPO is 100% recyclable.
• Exceptional resistance to solar UV, ozone and oxidation.
• True Thermoplastic - Heat welded repairs are easy.
• Hot melt extrusion processed for complete scrim encapsulation.
• TPO polymers contain no PVC's (chlorine free & plasticizer free) - non toxic, non shrink, no embrittlement, high flexibility.
• Full range of prefabricated accessories & adhesives available for the installation process.
• Warp polyester reinforcing knitted fabric (not woven) for smooth surface and greater thickness-over-scrim.
• Polyester reinforcing fabric is resistant to degradation by bacteria, mildew and fungi.
• Excellent chemical resistance to acids, and restaurant exhaust emissions.
• Smooth surface - total fusion weld, consistent watertight monolithic roof assembly, reduced dirt pickup, stronger weld, automation productivity 3-5 m/min.
• Thicker - outstanding breaking strength, excellent impact, puncture and hail resistance.
• Carlisle Fasteners - HP-X™ Fasteners and Piranha Plates™ are used to provide additional back out resistance.
