Carlisle’s Sure-Weld TPO is a highly reflective, single-ply roofing membrane that has become increasingly popular in warm, southern climates. The energy-efficient Sure-Weld membranes feature heat-weldable seams and are accompanied by a number of pre-fabricated, laborsaving accessories, saving contractors and building owners money through increased installation speed. Carlisle manufactures tapered polyiso, an energy-efficient insulation designed to minimize heating and cooling costs while promoting positive rooftop drainage for virtually any roofing application. By directing water to drains and scuppers, tapered polyiso reduces water infiltration and minimizes the negative effects of ponding water, ultimately lengthening the service life of a roof.
