Tpo Thermoplastic Versus Epdm Roofing
Tpo roofing membranes are more expensive than epdm.
Tpo thermoplastic versus epdm roofing. It is a synthetic rubber derived from oil and natural gas ethylene propylene. Tpo is much lighter and easier to install but epdm is a whole lot cheaper and lasts longer. Tpo can be slightly cheaper than epdm comparing standard tpo roofing vs. Regardless of which membrane you choose it is better to spend more money and invest into a thicker membrane.
Otherwise epdm roofing has worse performance and weaker seam strength meaning there is a greater risk of water intrusion where the sections of roofing connect. Tpo roofing has roughly the same lifespan as epdm roofing with both usually lasting 22 30 years. One advantage tpo roofing has over epdm roofing is enhanced durability. However in some cases tpo can be slightly less expensive.
However epdm isn t the holy grail of single ply flat roof membranes. The term tpo stands for thermoplastic polyolefin. Epdm offers a design life of 20 to 30 years and some reports put the life of epdm at. Tpo is thermoplastic so you can heat weld seams and it s ideal for repairs.
Epdm cannot be welded and cannot be re taped when the weather is too cold to use primer and adhesives requiring a temporary fix until the weather warms up. If your tpo roof has more than 25 saturation it s in your best interest to remove the tpo and insulation and install a new roofing system epdm ethylene propylene diene monomer is a single ply membrane that consists of a synthetic rubber compound that allows it to be flexible. If you are thinking of getting a new roof for your rv these two options are your best bet. Tpo is less susceptible to leaks since tpo roofs don t have big seams like epdm roofs this makes them less vulnerable to water leaks as they age.
Tpo is a blend of polypropylene and ethylene propylene rubber. Tpo roofing comes in a wide variety of colors including lighter colors that reflect uv rays and heat instead of absorbing it. Both epdm and tpo roofs perform better and last longer if they are thicker. Believe it or not tpo is actually in a broad family of rubber roofing materials.
Epdm roofs are the most economical choice for single ply roofing membranes. Tpo roofing vs epdm epdm roofing is made from ethylene propylene diene monomer or a kind of rubber its primary advantage over tpo roofing is simply that it s cheaper. Epdm stands for ethylene propylene diene monomer. Thermoplastic polyolefin tpo also offers a wide range of advantages despite the additional cost for property owners.
Epdm roofing the price is fairly comparable. Tpo and epdm might look the same when they are installed but they are vastly different in terms of construction and features.
