Pvc versus tpo two of the hardest flat roof systems to tell apart is the pvc roof and the tpo roof.
Tpo rooking versus pvc roofing.
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.
The seams are either glued with the rest of the roof different process same result or they are taped.
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.
It does not absorb or get weakened by oils and greases.
Like pvc two tpo plies sandwich a polyester reinforcement sheet.
Both membranes are heat weldable which makes them more resistant to leaks than epdm because of a reduced number of instances of seam failures.
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.
For example pvc has better chemical resistance.
Tpo vs pvc roofing.
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.
These descriptions don t do justice to the potential of both modified bitumen and tpo roofing systems.
Both are white heat welded systems that look virtually identical.
When it comes to a durable roof that is also environment friendly tpo roofing is a great option.
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.
This means that it requires glues to adhere it to what s underneath.
It does not absorb or get weakened by oils and greases.
Hot air welded seams help pvc roofing remain watertight under a variety of severe weather conditions.
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 in a nutshell a tpo membrane is made from ethylene propylene rubber.
While they share many qualities with pvc systems they typically come at a lower cost.
Pvc s are documented to last longer than tpo membranes who are still experiencing premature failures.
When deciding on which would be the best for your building consider the location and the budget that you have.
Tpo thermoplastic polyolefin to produce the tpo membrane manufacturers will polymerize polypropylene and ethylene propylene rubber.
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.
