STP Limited, India, waterproofers to the nation since 1935 and Carlisle SynTec Incorporated, USA, with over 40 years experience join hands to bring you the best waterproofing solutions. EPDM Roofing Systems 45 years ago, Carlisle pioneered single-ply roofing. Today, more than 12 billion square feet of membrane have been sold. No other manufacturer has a comparable track record. EPDM’s success is due to its many exceptional characteristics, including material longevity, weatherability and elasticity. These non-reinforced membranes are lightweight, easy to maneuver on the roof and offer optimal reroofing as well as new roofing solutions. Sure-Seal (black) EPDM (Ethylene Propylene Diene Monomer) nonreinforced membranes are available in standard 45-, 60- and 90-mil thicknesses. Membrane widths up to 50' and lengths to 200' which result in less rooftop seaming for large projects. Custom sizes may be requested. Fully-Adhered Systems utilizing EPDM require mechanical or adhesive attachment of the insulation and bonding of the membrane to the insulation with the recommended adhesive. Ballasted designs incorporate a loose-laid insulation and membrane and the use of ballast or pavers as securement. TPO MEMBRANE SYSTEMS Sure-Weld Thermoplastic Polyolefin (TPO) roof membranes are not adversely affected by most common materials and chemicals encountered in a roof environment.  Since the field seam is heat welded, it is as resistant to chemicals as the base sheet. The best course of action to take if unusual substances will contact the membrane, is to evaluate their effect on the membrane in the laboratory.  Carlisle SynTec's Laboratory is equipped to perform this testing, interpret the results, and provide a recommendation.  APP MEMBRANES STP has the largest range of Atactic Polypropylene modified bitumen membranes which include:

• Super Thermolay : It has a multilayered design consisting of a 160 gsm polyester core coated with APP (Atactic Polypropylene) modified bitumen and finally finished with thermo fusible polyethylene film.
• Aqua Shield : It has a multilayered design consisting of a 160 gsm fiberglass core coated with APP (Atactic Polypropylene) modified bitumen and finally finished with thermo fusible polyethylene film.
• Super Thermolay MT and Aqua Shield MT : These have mineral/slated finished as a top surface.
• Self Adhesive Membranes : It consists of self adhesive SBS (Styrene Butadiene Styrene) rubber/bitumen compound covered on the top side with high density cross laminated polyethylene film and on the underside with an easy-to-peel silicon film.
