This membrane is composed of three layers.
Thermoplastic pvc roofing.
Both pvc and tpo can be mechanically attached using plates and screws or adhered to the roof substrate.
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.
Tpo is a single ply roofing system that consisting of a thermoplastic polyolefin membrane.
Unlike pvc however tpo membranes do not adhere readily especially with water based adhesives.
The advantages include water tight seams sunlight resistance positive aesthetic and energy saving aspects of a white color roof and the economic benefits of a lightweight unballasted roofing system.
The most obvious similarity is that tpo thermoplastic olefin and pvc poly vinyl chloride are both thermoplastic materials.
Pvc has been used as a roofing material since the 1960s and has over 50 years of proven performance.
It s generally less expensive that pvc but more expensive than efdm.
Benefits of tpo and pvc flexible protection.
Pvc s are documented to last longer than tpo membranes who are still experiencing premature failures.
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.
Thermoplastic polyolefin tpo and polyvinyl chloride pvc are two types of single ply membranes utilized in low slope and flat roofing systems.
How is pvc installed on a roof.
Pvc roofing systems built to withstand the test of time our pvc roofing membranes are made to resist the toughest weather conditions and chemicals.
White tpo is highly reflective and can help lower energy costs in hot sunny places.
Tpo membranes are made with a co polymerized rubber that allows them greater flexibility in cold climates.
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.

Tpo is fairly new on the market and its longevity is largely untested.
The two thermoplastic materials demonstrate similar physical characteristics e g high strength durability and wind resistance.
This membrane is best recognized for having the benefits of epdm and pvc systems at a more economical cost.
Comprised of polypropylene and ethylene propylene rubber these materials are then polymerized together.
Tpo is a membrane roofing material in the same category as edpm and pvc.
The term stands for thermoplastic polyolefin a single ply reflective roofing membrane.
