The seams are either glued with the rest of the roof different process same result or they are taped.
Pvc vs tpo flat roofing.
Two of the hardest flat roof systems to tell apart is the pvc roof and the tpo roof.
This means that it requires glues to adhere it to what s underneath.
Pvc has been successfully used in commercial and residential roofing since the 1960 s while pvc is a newcomer and has been around since early 1990 s.
A pvc versus tpo comparison chart is below.
Both membranes are heat weldable which makes them more resistant to leaks than epdm because of a reduced number of instances of seam failures.
As noted in the chart below created from rs means data if you compare the life cycle costs of a sarnafil roof estimated to last 35 years versus a tpo roof lasting 20 years pvc is the less expensive choice.
It s therefore not surprising that tpo roofing systems are quickly growing in popularity and demand in both residential and commercial flat roof markets.
Unlike tpo and pvc roofs that are often mechanically attached an epdm roof is most often fully adhered.
This may surprise some diehard pvc users who may be unaware of the advances made in tpo formulation over the last several years.

Tpo vs pvc roofing.
If you are up for a more chemical resistant roofing and are looking for a cost friendly option pvc roofing is the way to go.
Initially tpo roofing was designed to be an improved version of both pvc and epdm rubber membranes combing the benefits of both but without the disadvantages.
However while the face of both membranes and their installation are virtually identical they are very different systems on the inside.
When it comes to a durable roof that is also environment friendly tpo roofing is a great option.
Pvc s are documented to last longer than tpo membranes who are still experiencing premature failures.
The most obvious similarity is that tpo thermoplastic olefin and pvc poly vinyl chloride are both thermoplastic materials.
Tpo in a nutshell a tpo membrane is made from ethylene propylene rubber.
Both are white heat welded systems that look virtually identical.
