WHAT IS IT?
The TPO membrane is a single-ply roof membrane constructed from high quality thermoplastic polyolefin. The standard color for this membrane is white; however, it is available as a special order in other colors depending on the manufacturer.
WHY USE TPO MEMBRANES?
TPO offers the “best of both worlds” combining the proven flexibility and weather resistance of rubber and the performance of hot-air welded thermoplastic seams. TPO seam strengths are reportedly 3 to 4 times those of EPDM’s adhesive and tape seams. TPO is highly resistant to tears, impacts, punctures, and ponding water. TPO is a lightweight single-ply membrane which is ideal for retrofit systems without adding excessive weight to the roof deck.
