TPO Advantages in Surrey BC Climate
- White reflective surface — reduces summer attic/building heat load; Energy Star certified products qualify for energy rebates
- Heat-welded seams — TPO seams are welded with hot air, creating a monolithic bond stronger than the membrane itself when done correctly. This is superior to EPDM tape-bonded seams in Surrey’s wet climate.
- Cold-weather flexibility — TPO remains flexible at low temperatures, important for Surrey’s winter installation windows
- Chemical resistance — resists oils, fats, and chemicals; good for restaurants, food processing, and automotive adjacent commercial properties
