Thermoplastic Polyolefin or TPO

TPO or thermoplastic polyolefin is one of the single-ply roofing materials that are popular. This is often used for industrial or commercial buildings because it has a single layer of synthetics. This single layer helps to reinforce the scrim. Because TPO is considered a single-ply, it means that it is installed onto the roof in one layer instead of multiple layers.

•         Reflects UV rays.
•         It’s considered to be inexpensive compared to other commercial roofing systems.
