Thermoplastic Polyolefin Membrane Roofing

Epdm an example of thermoset roofing membranes.

Thermoplastic polyolefin membrane roofing. In general these warranties cover defects in the manufacture of the roof membrane. This membrane is composed of three layers. Tpo membranes are white and highly reflective making them an excellent choice for those looking to reduce. Astm d6878 standard specification for thermoplastic polyolefin based sheet roofing warranties when purchasing a new roof system there will be two warranties to consider.

As demand increases for heat reflective and energy efficient roofing systems you can rely on tpo single ply roofing membranes to. As demand increases for heat reflective and energy efficient roofing systems you can rely on tpo single ply roofing membranes to. Thermoplastic polyolefin is a single ply roofing membrane that is one of the fastest growing commercial roofing systems on the market. Tpo is a single ply roofing system that consisting of a thermoplastic polyolefin membrane.

First there will be the manufacturer s warranty. Tpo based products have been available since the 1980s. In the building trades the acronym tpo stands for thermoplastic polyolefin a material originally developed for pond liners and used extensively for roofing since 1989 it s a single ply membrane made from a polymerized combination of polypropylene and ethylene propylene rubber that can be attached to a roof with adhesive or with mechanical fasteners. Tpo membranes are made with a co polymerized rubber that allows them greater flexibility in cold climates.

To understand why tpo membranes are the fastest growing segment of the membrane market a little background is in order. Thermoplastic polyolefin tpo single ply roofing membranes are among the fastest growing commercial roofing products and have gained praise across the industry for their many performance and installation advantages. A quality thermoplastic polyolefin tpo roof system will offer many benefits including cool roof properties that help reduce the load on hvac equipment reduce temperatures in interior unconditioned spaces and a robust weathering package that can withstand over 60 days at 275 degrees fahrenheit without cracking or showing signs of material failure. These membranes are made from chemically inert substances similar to materials that make up the tire rubber.

On the other hand polyvinyl chloride pvc and thermoplastic polyolefin tpo two other common roofing systems for commercial buildings fall in the second category.
