Are there different types of EPDM?

The three types of EPDM installation are ballasted, fully adhered and mechanically attached.

What does EPDM stand for?

ethylene propylene diene monomer
EPDM stands for ethylene propylene diene monomer, which is a bit of a mouthful, so it’s commonly shortened to EPDM or EPDM rubber. EPDM gets its name from the chemicals (monomers) that are mixed together in various proportions to form it. These are ethylene, propylene and diene.

What thickness of EPDM is best?

Long-Term Lifespan Roofing installation experts will recommend 45 Mil EPDM rubber roofing membrane in moderate climates and in situations where there’s a low risk of penetrations. While these typically last 12-15 years, by going with a 90 Mil option can get users 25-years or more easily.

Is EPDM better than rubber?

EPDM vs. SBR: Ethylene propylene rubber performs better than Styrene-Butadiene rubber (SBR) in nearly every way. EPDM has a lower compression set, a higher tensile strength, a better resistance to heat aging, and high weathering resistance. The rubber is also more resistant to water swell and weathering elements.

Is rubber better than silicone?

Silicone also has significantly better flame resistance than natural rubber. For high temperature applications, silicone is certainly the better choice….Silicone vs Natural Rubber.

Natural Rubber	Silicone
Approx. tensile strength 25 MPa	Approx. tensile strength 5 MPa
Excellent abrasion resistance	Poor abrasion resistance

What size does EPDM come in?

Full Answer. The biggest sheet sizes available come from our ClassicBond® EPDM range. These sheets can be supplied in one continuous sheet up to 15.25 metres x 30.5 metres in the 1.2mm thick membrane and 15.25 metres x 15.25 metres in the 1.5mm thick membrane.

What is the difference between TPO and EPDM?

TPO roofing reflects sunlight, allowing commercial air conditioners to work more efficiently; whereas EPDM has a dark surface, which in summer conditions will absorb heat, forcing cooling systems to work overtime. TPO offers reduced cooling costs and energy savings for facilities located in warmer climates.

Is EPDM silicone free?

EPDM, on the other hand, is a more specialized rubber that costs less and performs better under specific applications. Although both rubbers are considered waterproof, silicone swells when exposed to water, while EPDM stays constant.
