Tpo membrane can provide combined benefits of both epdm rubber and pvc roofs but at a more economical cost than pvc.
Pvc vs tpo flat roofing.
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.
Unlike tpo and pvc roofs that are often mechanically attached an epdm roof is most often fully adhered.
It s therefore not surprising that tpo roofing systems are quickly growing in popularity and demand in both residential and commercial flat roof markets.
Flat roof materials installation costs 2020.
When deciding on which would be the best for your building consider the location and the budget that you have.
In the current single ply roofing market the two most popular options are thermoplastic membranes pvc and tpo.
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.
This means that it requires glues to adhere it to what s underneath.
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.
This may surprise some diehard pvc users who may be unaware of the advances made in tpo formulation over the last several years.

Pvc s are documented to last longer than tpo membranes who are still experiencing premature failures.
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.
When it comes to a durable roof that is also environment friendly tpo roofing is a great option.
Two of the hardest flat roof systems to tell apart is the pvc roof and the tpo roof.
The most obvious similarity is that tpo thermoplastic olefin and pvc poly vinyl chloride are both thermoplastic materials.
The seams are either glued with the rest of the roof different process same result or they are taped.
In terms of weathering i e based on the heat aging and the accelerated weathering tests tpo has the clear edge over pvc.
However while the face of both membranes and their installation are virtually identical they are very different systems on the inside.

Tpo in a nutshell a tpo membrane is made from ethylene propylene rubber.
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.
