Thermoplastic polyolefin, or TPO, is the fastest-growing segment of the commercial roofing industry, and Carlisle is the leading supplier of this type of roofing material. Carlisle’s white and tan Sure-Weld® TPO membranes are ENERGY STAR®-rated and Cool Roof Rating Council (CRRC)-certified, and have been directly attributed to a reduction in a building’s energy use and cooling costs.

Sure-Weld membranes are available in sizes up to 12-feet wide and 200-feet long, making installation of a Sure-Weld roof system fast and efficient. Adding to the efficiency of a Sure-Weld installation are Carlisle’s prefabricated accessories that drastically reduce the amount of time needed to flash rooftop penetrations.
