Keeping this in view, is EPDM better than TPO?
That being said, TPO seams tend to be much stronger than EPDM seams because of the way they are adhered to the roof. While EPDM is usually placed in a single sheet without seams, if there are seams, they may not be as strong.
Furthermore, what is a TPO membrane? TPO stands for thermoplastic polyolefin, a single-ply roofing membrane that covers the surface of the roof. The name is a bit misleading, because rather than being a plastic, TPO is actually one of a few different types of rubber, usually a blend of polypropylene and ethylene-propylene rubber.
In this regard, how do you tell the difference between TPO and PVC roofing?
The most significant difference between PVC and TPO roofs is their chemical makeup. TPO was designed to be a superior material to PVC. However, because the goal was to make TPO cheaper, the final formulation of the membrane turned out to be substandard.
Is TPO more expensive than EPDM?
TPO membrane can provide combined benefits of both, EPDM rubber and PVC roofs, but at a more economical cost than PVC. It's therefore not surprising that TPO roofing systems are quickly growing in popularity and demand, in both residential and commercial flat roof markets.
