Thermoplastic Polyolefin (TPO): What You Need To Know
Considered a single-ply reflective roofing membrane system, Thermoplastic Polyolefin (TPO) is constructed from polypropylene as well as ethylene-propylene rubber that is polymerized together. As a general rule, it is installed as a system that it mechanically attached or fully adhered. This allows the white-colored membrane to be exposed, and visible, throughout the roof’s life. In 1989, the very first sheet of the roofing membrane was installed. Since then, there have been millions of square meters of this roofing system installed across the world.
Cooling Degree Days
These particular types of roofing membranes are very popular in regions that have a higher number of cooling degree days, which is when the temperatures are higher and cooling equipment is utilized, than heating degree days. These membranes have the ability to reflect UV rays, which ensures that the roof’s surface as well as the building remains cool throughout the hotter times of the year. This assists in reducing cooling costs and decreases how much carbon emissions are released into the air.
Sustainability and Reflectivity
Many organizations and companies are happy about the environmentally benefits that TPO membranes offer. One company turned their building into the most energy-efficient building in the city when they installed a TPO roof. TPO operates at under 9kWh per square foot and uses roughly 90 percent less energy than other buildings of similar size. TPO offers reflective roofing that can work in combination with solar panels and skylights, which further help ERC to reach that remarkable degree of sustainability.
Versatility, Flexibility and Durability
TPO is able to be installed on a variety of surfaces, including those with low or high slopes, and has the ability to be heated and then reshaped several times, which is beneficial when roof details need to be completed. This particular type of roof is particularly resistant to impacts, tears and punctures, though it still remains completely flexible. It is available in three different thicknesses – 0.045 inches, 0.060 inches and 0.080 inches.
Easy to Install and Economical
Thanks to its flexibility, TPO is one of the easiest and fastest types of roofing systems to install. In addition, it requires minimal maintenance throughout its entire life. The TPO membrane generally mechanically attaches or fully adheres to the underlying insulation or the cover board. They come in rolls that range from 5-foot by 100-foot to 12.4-foot by 200-foot, which helps to reduce the overall number of cuts and seams that need to be made as well as labor costs.
Cool Roofing Is Important
The lighter color roof you have, the better it will reflect the sun. As a result, you will experience a significant reduction in energy costs. It will also help reduce the urban heat island (UHI) effect, which is helpful to the surrounding environment.
With a hot-air gun, TPO membranes are welded at 800-1000 degrees Fahrenheit. As a result, the seams are fused for long-lasting performance.
Environmentally-Friendly and Sustainable
These roofing systems contain absolutely no hazardous or toxic ingredients and they are 100 percent recyclable.
