What Is a TPO Roof and Why Businesses Choose It
TPO (Thermoplastic Polyolefin) is a single-ply membrane made from polypropylene and EPDM rubber reinforced with a polyester scrim. It’s flexible, puncture-resistant, and heat-weldable unlike traditional glued systems.
Core Advantages:
- Superior Durability: Reinforced seams are up to 3 × stronger than the membrane itself.
- Cool Roof Technology: White TPO reflects 70–80 % of sunlight and re-emits 85–90 % of heat, lowering HVAC load.
- Chemical Resistance: Resists oils, ozone, and acid rain.
- Eco-Friendly: Contains no chlorine or plasticizers and is 100 % recyclable.
- Low Maintenance: Smooth surface resists mold, dirt, and algae growth.
Available in 45 mil, 60 mil, and 80 mil thicknesses, TPO membranes meet ASTM D6878 standards for tensile strength, tear resistance, and UV aging, backed by 20- to 30-year warranties from top manufacturers.
