The Thermoplastic Polyolefin Roofing System (TPO) is a type of single ply synthetic rubber roofing. It is the fastest growing commercial roofing product, and comes with many performance and installation advantages, including heat reflectivity and energy savings. While it is a relatively new product, and testing is still being performed on longer based applications, results so far are good that this is a roofing system that will protect your building for a long time to come.
Because TPO roofing is a polypropylene based plastic rubber blend the TPO membrane can remain durable and flexible even in low temperatures. The TPO membranes are sealed together using heat welding, creating a lasting bond that will seal the whole surface of your roof.
Chemicals added during the creation process allow for UV stabilization, which creates long-term weather resistance and durability. Fire retardants like magnesium hydroxide are also added during creation, to add an extra level of fire resistance and safety to your roof without harming the environment.
Pigments are added to help increase the whiteness of the product, giving you the most energy savings by reflecting UV rays from the sun.
TPO reflective membranes meet LEED® and ENERGYSTAR® certifications, and while no roof lasts forever one of the advantages for TPO membranes is that it is environmentally friendly can be recycled with other plastics.
