It depends on the quality of installation but on average exposed fastener metal roofs which do indeed use edpm washers if not of very low quality and life expectancy are a 15 25 year roof while a quality standing seam job is a 50 year roof.
Neoprene vs epdmm roof.
The generic name for neoprene is polychloroprene.
Epdm or ethylene propylene diene monomer was developed in the 1960s and is commonly used on flat roofs.
However unlike neoprene epdm swells if put in contact with petroleum oil fluid or solvent.
Key difference neoprene vs epdm.
It s made of a mixture of recycled tires sawdust and slate dust and runs roughly 80 a square foot making it one of the least expensive types of roofing on the market today.
Epdm roofing is most commonly known as rubber roofing rubber membrane roofing or rolled rubber roofing.
In compression set neoprene is right there with epdm though neither match silicone in that area.
However commonly epdm is an excellent choice for outdoor applications and is a popular choice within the automotive industry.
Gaskets and sealing with epdm and neoprene.
Epdm is also used in seals and tubing as electrical insulation in pond liners and as a motor oil additive.
They are produced in two different ways so that their properties and applications differ accordingly.
Neoprene matches epdm stride for stride in properties such as compression set resilience and even ozone resistance.
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.
While both neoprene and epdm rubber have their benefits at houston products inc.
General purpose neoprene gaskets and foam sheets can also be used in many industrial and automotive environments.
The key differences between neoprene and epdm arise due to their structural difference.
We feel the optimal choice between the two is clear.
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.
Although epdm roofing systems have been the industry leader for more than half a century now for single ply roofing tpo is rapidly gaining in popularity on epdm and may even overtake it as the preferred industry choice in the near future.
As our standard manufacturing material epdm offers consumers far greater durability and flexibility and is suited to a broader range of applications than its alternatives.
Epdm functions better in higher temperatures with a maximum of 300 350 degrees f while neoprene handles only up to 225 degrees f.
Neoprene and epdm are two synthetic rubber categories which are widely used in a wide range of modern industrial applications.
Both materials are considered to be excellent all purpose fabrics.
It s also steam resistant and more ozone resistant.
For certain applications epdm is the cheaper option of the two rubbers.
