Thermoplastic polyolefin tpo and polyvinyl chloride pvc are two types of single ply membranes utilized in low slope and flat roofing systems.
Thermoplastic pvc roofing.
The term stands for thermoplastic polyolefin a single ply reflective roofing membrane.
Comprised of polypropylene and ethylene propylene rubber these materials are then polymerized together.
Pvc roofing systems built to withstand the test of time our pvc roofing membranes are made to resist the toughest weather conditions and chemicals.
The typical installation setup is on a fully adhered or mechanically attached system.

Thermoplastic roofing tpo pvc the thermoplastic single ply roofing systems are suitable for a wide variety of roofing applications.
Tpo is fairly new on the market and its longevity is largely untested.
Unlike pvc however tpo membranes do not adhere readily especially with water based adhesives.
Tpo membranes are made with a co polymerized rubber that allows them greater flexibility in cold climates.
Jm pvc with dow elvaloy kee and jm pvc sd plus thermoplastic roofing membranes are manufactured using an ultraviolet resistant polyvinyl chloride.
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.
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.
Pvc has been used as a roofing material since the 1960s and has over 50 years of proven performance.
Similarities of tpo and pvc roofing membranes 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.
How is pvc installed on a roof.
Benefits of tpo and pvc flexible protection.
This membrane is composed of three layers.
It s generally less expensive that pvc but more expensive than efdm.
Tpo is a single ply roofing system that consisting of a thermoplastic polyolefin membrane.
This membrane is best recognized for having the benefits of epdm and pvc systems at a more economical cost.
The tpo membrane was first introduced to the roofing market in the early 1990 s as a more economical and efficient alternative that was thought to replace pvc roofing products.
White tpo is highly reflective and can help lower energy costs in hot sunny places.
The two thermoplastic materials demonstrate similar physical characteristics e g high strength durability and wind resistance.
