Is TPO better than EPDM?
TPO has better dimensional stability than EPDM. EPDM is more likely to shrink which can cause a variety of problems on your roof.
Can you use TPO as a pond liner?
Pond liners made from synthetic rubbers are significantly more flexible and durable than liners made from plastics such as polyvinyl chloride (PVC), high-density polyethylene (HDPE), Polypropylene (PP), or thermoplastic polyolefin (TPO).
Is roofing EPDM safe for ponds?
High-density polyethylene is considered by many to be the premium choice. It’s flexible, highly puncture resistant and lighter than a lot of the other materials available. Another common material used for pond liners is ethylene propylene diene terpolymer, or EPDM.
How long should a TPO roof last?
15 to 20 years
A TPO roof membrane can last anywhere from 15 to 20 years. It is a single ply reflective roofing option, and it is typically adhered or mechanically attached. This membrane can be left exposed throughout its life.
Can you put EPDM over TPO?
Yes. Recovering with TPO is a great option for a building with an aging EPDM roofing system. It’s easy.
Can you walk on pond liners?
You can walk on it, even with your shoes, and if you use the recommended underlayment it can be reasonably difficult to puncture, but it can be easy to slice. Always be especially careful not to drag rocks, your feet, rakes, or whatever across the liner.
What is EPDM rubber roofing?
What is EPDM? Ethylene Propylene Diene Monomer (M-class), or EPDM, is a synthetic rubber that is extremely durable and used across a variety of applications. EPDM is heat and weather resistant with its two main ingredients derived from natural gas and oil, making it an ideal flat roofing material.
Is EPDM fish safe?
EPDM resists harmful UV deterioration. Since the rubber does not contain any plasticizers, it does not become brittle or crack and is completely safe to use with fish and plants! This liner material is backed by a 25-year warranty; a lifetime warranty installed with UnderGuard Geotextile Underlayment.
What are the advantages of TPO?
TPO membranes are highly durable. They hold up well to long-term exposure to the sun’s ultraviolet light, and they are highly resistant to puncturing, tearing, or water damage. They are even resistant to bacterial growth and dirt buildup, so it will be easier for you to keep your roof clean.
