TPO polymers are blends or alloys of EBR (polypropylene plastic or polypropylene and ethylene propylene rubber) and EPDM (ethylene propylene diene terpolymer rubber). Other additives are included in the mixture before it is formed into a roofing membrane. The membrane is attached to the roof board with fasteners. When combined with several other elements (like a weathering package, fire retardants, and insulation), the TPO membrane becomes a part of an entire roofing system.
Calendaring with lamination, extrusion with lamination, or extrusion-coating techniques is used to create TPO membranes. A blend of polypropylene and ethylene propylene polymers are usually reinforced with polyester to create TPO sheets. TPO sheets contain colorant, flame retardants, UV absorbers, and other proprietary substances are used to achieve desired physical properties.
Comparatively new in commercial roofing in today’s market, TPO has quickly climbed its ranks. TPO is designed to be the perfect combination of EPDM (rubber) and PVC (polyvinyl chloride). This makes it one of the most popular roofing products available these days. Not only is it very resistant to harsh temperatures and wild weather, but it is also flexible and very strong. Despite many advantages, it lacks the long track record that more traditional roofing systems boast.
Read on if you’re interested in learning more about the composition and advantages of a TPO roofing system. We will be glad to help you decide if TPO is right for your building.
TPO is incredibly popular because of its strength, ease of installation, and longevity. It can be heat-welded during installation due to the material’s thermoplasticity, which is a huge advantage since seams are usually the weakest part of a roof. In fact, TPO seams are said to be 3-4 times stronger than EPDM systems and 6 times stronger than systems that use glue seams or tape systems. They are resistant to chemicals, do well in high heat, are flexible in cold temperatures, and are generally quite affordable. With proper installation and maintenance, TPO systems can last 10-20 years. Finally, if it is important to you that your roof is environmentally-friendly, you have no need to fear TPO!
No plasticizers are involved in TPO roofing systems, they don’t degrade under UV radiation, and they come in white (which reflects heat, helping the building stay cool). Plus, they can be made from some recycled materials. TPO is the perfect choice for your “green” building.
