TPO (thermoplastic olefin) offers unparalleled roof protection. The ease of application makes TPO a perfect option for a variety of applications. One application is this overlay retrofit for an office roof in St. Charles, Illinois.
This Firestone TPO membrane is EnergySTAR®-rated and Cool Roof Rating Council (CRRC)-certified. TPO has been directly attributed to a reduction in a building’s energy use and cooling costs and was a perfect choice for the office roof.
