Carlisle pioneered the US Production of sheet membrane roofing materials and provides the best, long-term single-ply roofing systems in the commercial and industrial roofing applications.

System features and benefits include:

	Heat-weldable membranes
	High wind uplift performance
	Hail and High Puncture Resistance
	Top Ply membrane thickness adds improved long-term weatherability and durability

EPDM Roofing Systems

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 Terpolymer) non-reinforced membranes, in 45-, 60- and 75-mil thicknesses, are manufactured with a polyester reinforcement completely encapsulated between two plies of EPDM; the membrane offer greater fatigue and puncture-resistance.

TPO Roofing systems

The membrane is comprised of three layers- A TPO polymer base, a strong, polyester-reinforced fabric center (scrim) and a tough thermoplastic polyolefin compounded top ply. Because the top ply is the most vital membrane component for long-term weathering characteristics, Carlisle manufactures its membranes with an industry leading "thicker" and "smoother" top ply coverage. The smooth surface resists dirt pick-up and biological growth compared to other thermoplastic membranes.

Sure-Weld membranes are ideally suited when environmental issues are of concern because the membrane is produced without the use of any chlorinated ingredients or plasticizers. Sure-Weld membrances are 100% recyclable.
