This means that it requires glues to adhere it to what s underneath.
Tpo rooking versus pvc roofing.
Tpo vs pvc roofing.
Both are white heat welded systems that look virtually identical.
While tpo has superior weathering and slightly better tear and break resistance than pvc pvc does have some characteristics that certain customers need or prefer.
Tpo thermoplastic polyolefin to produce the tpo membrane manufacturers will polymerize polypropylene and ethylene propylene rubber.
These descriptions don t do justice to the potential of both modified bitumen and tpo roofing systems.
Both membranes are heat weldable which makes them more resistant to leaks than epdm because of a reduced number of instances of seam failures.
Hot air welded seams help pvc roofing remain watertight under a variety of severe weather conditions.
It does not absorb or get weakened by oils and greases.
Unlike tpo and pvc roofs that are often mechanically attached an epdm roof is most often fully adhered.
For example pvc has better chemical resistance.

Tpo membrane can provide combined benefits of both epdm rubber and pvc roofs but at a more economical cost than pvc.
Moreover like pvc tpo is considered a green roofing material and can save you money on your electricity bills because both membranes are white in color and possess reflective cool roof properties.
While they share many qualities with pvc systems they typically come at a lower cost.
The seams are either glued with the rest of the roof different process same result or they are taped.
While tpo has superior weathering and slightly better tear and break resistance than pvc pvc does have some characteristics that certain customers need or prefer.
For example pvc has better chemical resistance.
The most obvious similarity is that tpo thermoplastic olefin and pvc poly vinyl chloride are both thermoplastic materials.
However while the face of both membranes and their installation are virtually identical they are very different systems on the inside.
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 does not absorb or get weakened by oils and greases.
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.
Pvc s are documented to last longer than tpo membranes who are still experiencing premature failures.
Tpo in a nutshell a tpo membrane is made from ethylene propylene rubber.
Pvc versus tpo two of the hardest flat roof systems to tell apart is the pvc roof and the tpo roof.
When it comes to a durable roof that is also environment friendly tpo roofing is a great option.
