Thermoplastic roof membranes are materials that have chemical and physical properties that allow them to soften when heated and harden when cooled repeatedly. Due to their nature, thermoplastic membrane sheets are seamed with hot air welding.
Two common categories of thermoplastic membrane sheets include Thermoplastic Olefin (TPO) and Polyvinyl Chloride (PVC). The membrane is often produced as a reinforced, white sheet whose thickness ranges from 45 to 80 mils (thousandths of an inch). Optional colors can be chosen and warranties are available for up to 20 years.
Thermoplastic membrane installation for commercial roofing systems is either completely adhered or mechanically attached.
