Pvc s are documented to last longer than tpo membranes who are still experiencing premature failures.
Tpo vs pvc for flat roofs.
Pvc is a plastic roof material that is formed by a gaseous reaction between oxygen hydrochloric acid and ethylene.
In terms of weathering i e based on the heat aging and the accelerated weathering tests tpo has the clear edge over pvc.
Tpo requires an experienced worker to ensure seamless and effective welding.
According to the american society of testing and materials astm a roofing membrane must have a breaking strength of around 200 ppi.
The most obvious similarity is that tpo thermoplastic olefin and pvc poly vinyl chloride are both thermoplastic materials.
Flat roof materials installation costs 2020.

However while the face of both membranes and their installation are virtually identical they are very different systems on the inside.
The material is the third most widely produced synthetic plastic polymer.
When used for roofing pvc is possible for prefabrication during the manufacturing phase.
Unlike tpo and pvc roofs that are often mechanically attached an epdm roof is most often fully adhered.
Both are white heat welded systems that look virtually identical.
This may surprise some diehard pvc users who may be unaware of the advances made in tpo formulation over the last several years.
