TPO,
TPO roofing is a relatively inexpensive rubber roofing material that's most often used on commercial buildings. TPO stands for
Thermoplastic Polyolefin; it's made primarily from recycled rubber, and sold in rolls that are held together by seams that are “glued” together using heat.
Floors, walls, ceiling and roof.
Outdoors it has 15-25 year life depending on its thickness.
Indoors it will last indefinitely.
I have used it for years in my grow rooms.
Never has failed. Has the most reflectivity on the market besides PVC.
PVC,
PVC is a
high quality, durable option for commercial roofs. ... Made from polyvinyl chloride (or in layman's terms, plastic), PVC is a great single-ply roofing solution. It's made from a lower percentage of oil and petroleum than thermoplastic polyolefin (TPO) or ethylene propylene diene terpolymer (EPDM)
PVC is a much more superior product to TPO
But with the shortages we are seeing at this point the cost difference has made tpo just as expensive at pvc.
the pics below are TPO installation,
PVC would be the exact same installation but PVC is a heavier product.
