It is a synthetic rubber derived from oil and natural gas ethylene propylene.
Tpo thermoplastic versus epdm roofing.
Believe it or not tpo is actually in a broad family of rubber roofing materials.
Tpo roofing comes in a wide variety of colors including lighter colors that reflect uv rays and heat instead of absorbing it.
Tpo is thermoplastic so you can heat weld seams and it s ideal for repairs.
Tpo roofing has roughly the same lifespan as epdm roofing with both usually lasting 22 30 years.
Tpo is a blend of polypropylene and ethylene propylene rubber.
Tpo can be slightly cheaper than epdm comparing standard tpo roofing vs.
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.
However in some cases tpo can be slightly less expensive.
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.
Epdm stands for ethylene propylene diene monomer.
Tpo is much lighter and easier to install but epdm is a whole lot cheaper and lasts longer.
Simply clean the membrane and heat weld directly to it.
While epdm roofing has been in use for decades tpo is a more recent addition to the single ply roofing market.
If you are thinking of getting a new roof for your rv these two options are your best bet.
Both epdm and tpo roofs perform better and last longer if they are thicker.
The term tpo stands for thermoplastic polyolefin.
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.
Regardless of which membrane you choose it is better to spend more money and invest into a thicker membrane.
However epdm isn t the holy grail of single ply flat roof membranes.
Tpo and epdm might look the same when they are installed but they are vastly different in terms of construction and features.
Tpo roofing membranes are more expensive than epdm.
Epdm roofing the price is fairly comparable.
Thermoplastic polyolefin tpo also offers a wide range of advantages despite the additional cost for property owners.
To finally settle the score between epdm vs tpo a side by side comparison will help property owners make the right decision for their properties.
Epdm offers a design life of 20 to 30 years and some reports put the life of epdm at.
Epdm roofs are the most economical choice for single ply roofing membranes.
