Carlisle SynTec Systems has introduced Sure-Flex™ PVC and KEE HP membranes with APEEL™ Protective Film. APEEL Protective Film guards the membrane’s surface from scuffs and dirt accumulation during installation, eliminating the need to clean the roof upon project completion. Patented Sure-Flex PVC and KEE HP membranes with APEEL Protective Film are ideal for re-roofing, re-cover and new construction projects; and can be used on the whole roof or only in areas that are subject to heavy soiling, such as loading areas.
