Thermoplastic Olefin Roofing

It gives roof surfaces a weather resistant coating that looks and feels much like rubber.

Thermoplastic olefin roofing.

By 1993 the earlier non reinforced membranes were replaced by fabric reinforced sheets the version available today. Comparing thermoplastic polyolefin roofing with epdm. Epdm an example of thermoset roofing membranes. Tpo s long term heat uv and natural fungal resistance plus flexibility without need for plasticizers also make tpo a reliable low slope roofing system.

The result was a new 60 mil mechanically attached tpo roof all installed during the plant shutdown. An example of thermoset membranes includes ethylene propylene diene monomer epdm one of the most widely used roofing systems. 60 mil mechanically attached tpo over hd isocyanurate square footage. On the other hand polyvinyl chloride pvc and thermoplastic polyolefin tpo two other common roofing systems for commercial buildings fall in the second category.

This means that a tpo roof is as uv resistant and as heat resistant as epdm and as heat weldable. Synthetic rubber and thermoplastics serve as two of the most widely used materials for low slope roofing applications. Tpo is touted to have the benefits of two of its direct competitors epdm and pvc roofs but without the drawbacks and extra costs. Outdoor applications such as roofing frequently contain tpo because it does not degrade under solar uv radiation a common problem with nylons.

Epdm ballasted roof after. To understand why tpo membranes are the fastest growing segment of the membrane market a little background is in order. Heat welded seams provide superior strength. Centimark stepped in to replace the roof within the time schedule completing over 100 000 square feet in less than 30 days.

Tpo based products have been available since the 1980s. Short for thermoplastic polyolefin tpo is a single ply roofing membrane that offers excellent performance at a cost effective price. Thermoplastic polyolefin is a polymer used to coat low slope or flat roofing especially in commercial properties. Astm d6878 standard specification for thermoplastic polyolefin based sheet roofing warranties when purchasing a new roof system there will be two warranties to consider.

First there will be the manufacturer s warranty. Thermoplastic olefin thermoplastic polyolefin tpo or olefinic thermoplastic elastomers refer to polymer filler blends usually consisting of some fraction of a thermoplastic an elastomer or rubber and usually a filler. While the rubbery coating is durable it isn t the most stylish feature for a property. The first sheets for membrane roofing were introduced in 1989.
