TPO & PVC ROOFING SYSTEMS
TPO and PVC are both thermoplastic membrane roofing systems.
Thermo Plastic Olefin (TPO) is a thermoplastic membrane, which incorporates a reinforcement scrim layer between plies of the membrane. The top ply typically contains cool-roof pigments, and UV stabilizers. The bottom ply is composed of TPO filler components that weld the plies together. Properly installed TPO roofing systems can typically last anywhere from 25-30 years.
Polyvinyl Chloride (PVC) a thermoplastic membrane that likewise uses a reinforcement scrim layer between plies of the membrane. Similar to TPO, a PVC roofing system uses cool-roof pigments and UV stabliizers in the top layer. The bottom ply is composed of PVC filler ingredients that weld the plies together. A properly installed PVC roof can also last between 25-30 years.
TPO BENNIFITS
- TPO roofing systems have superior weather, puncture and tear resistance, over PVC roofing. Properly installed, TPO also does not shrink like a PVC roof can.
PVC BENNIFITS
- PVC roofing systems have better resistance to chemical, oil and grease exposure (which often make them the preferred choice for food service, and restaurants etc). A PVC roofing membrane is also typically more flexible than TPO.
