Tpo Pvc Epbm Roof
Epdm stands for ethylene propylene diene monomer.
Tpo pvc epbm roof. The cost may be higher or lower depending on the tear off and removal cost of the existing roof insulation layers and the number of penetrations on your flat roof. Modified bitumen one potential area of concern with single ply roofing membranes including tpo epdm and pvc is that although these roof membranes are durable sharp objects and collisions can still rip through the single ply of the membrane. The most obvious similarity is that tpo thermoplastic olefin and pvc poly vinyl chloride are both thermoplastic materials. Pvc stands for polyvinyl chloride.
Expect to pay between 5 50 and 9 50 per square foot to install epdm membrane on a typical flat roof or about 8 250 to 14 250 for a 15 square 1 500 square feet low slope roof. It is one of the strongest flat roof materials amongst tpo epdm and mod bit. Tpo in a nutshell a tpo membrane is made from ethylene propylene rubber. According to the american society of testing and materials astm a roofing membrane must have a breaking strength of around 200 ppi.
That s a 50 increase for pvc and epdm and a 93 increase for tpo. Tpo membrane can provide combined benefits of both epdm rubber and pvc roofs but at a more economical cost than pvc. The material is the third most widely produced synthetic plastic polymer. 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.
The normal top range for single ply roofing membranes is 90 for pvc and epdm and 80 for tpo roofing. It s also a single ply roofing solution used on commercial roofs. Tpo is the most popular rv roofing material today because of two reasons it is cheap and it is already colored white. Modified bitumen features an advantage in this aspect since it is a multi ply roofing material.
It s therefore not surprising that tpo roofing systems are quickly growing in popularity and demand in both residential and commercial flat roof markets. It instantly became very popular as it was economical and cost efficient. Tpo which is short for thermoplastic polyolefin came into the roofing market in the early 1990s as a viable alternative to pvc roofing materials. Tpo is a blend of polypropylene and ethylene propylene rubber.
Believe it or not tpo is actually in a broad family of rubber roofing materials. The term tpo stands for thermoplastic polyolefin. Aside from this base material manufacturers reinforce the material with fiberglass and talc. Tpo requires an experienced worker to ensure seamless and effective welding.
Usually these get used on flat or low sloped roofs. When used for roofing pvc is possible for prefabrication during the manufacturing phase.
