Tpo Vs Edpm Rv Roofing

It is a synthetic rubber derived from oil and natural gas ethylene propylene.

Tpo vs edpm rv roofing. Epdm vs tpo is at par with longevity with tpo having roughly the same lifespan as epdm with 22 30 years. Tpo is a blend of polypropylene and ethylene propylene rubber. 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.

Tpo however requires more maintenance as you need to treat its seams with an adhesive causing it to be prone to coming apart. Mechanical installation for optimum roof security contractors use the mechanically attached system when installing tpo on flat roofs. For that reason epdm roofs tend to be more economical which is especially true when a single ply roofing membrane is required. It s important to factor in the thickness of any membrane when weighing up the costs thicker will generally cost more.

Tpo also has a somewhat higher resistance to punctures than epdm. They achieve this with fastening plates to secure the roofing material. Tpo is a versatile membrane and can be installed in a variety of ways including mechanically attached adhered and with the rhinobond system. One advantage tpo roofing has over epdm roofing is enhanced durability.

Tpo roofing has roughly the same lifespan as epdm roofing with both usually lasting 22 30 years. Rhinobond is an electromagnetic induction welding system and cannot be used with thermoset products such as epdm. For most rv roofing projects a tpo membrane is going to cost you more than an equivalent epdm membrane. Generally speaking there are four different kinds of roofing material used on an rv.

During the early parts of its service life you can expect an epdm membrane to not require a lot of maintenance provided it was installed properly. An epdm rv roof ethylene propylene diene monomer or a tpo rv roof thermal poly olefin. Regardless of which membrane you choose it is better to spend more money and invest into a thicker membrane. Tpo roofing membranes are more expensive than epdm.

Epdm stands for ethylene propylene diene monomer. Epdm has a dark surface which in summer conditions will absorb heat forcing cooling systems to work overtime whereas tpo roofing reflects sunlight allowing commercial air conditioners to work more efficiently. Epdm roofs are the most economical choice for single ply roofing membranes. Tpo and epdm might look the same when they are installed but they are vastly different in terms of construction and features.

Manufacturers add fiberglass and talc to tpo roofing to improve their durability.
