Thermoplastic Roof Membranes

There are several ways of connecting pieces of this material.

Thermoplastic roof membranes.

Thermoplastic membrane roofing becomes soft when heated then hardens and binds when cooled. Tpo is durable enough to resist punctures and flexible enough to stretch as the structure settles. This membrane is composed of three layers. The heating process can usually be repeated as needed.

Tpo membranes are white and highly reflective making them an excellent choice for those looking to reduce energy costs. A tpo roof costs between 5 50 and 9 50 per square foot. Modified bitumen this type of roofing is an evolution of asphalt roofing. Epdm an example of thermoset roofing membranes.

Tpo membranes are made with a co polymerized rubber that allows them greater flexibility in cold climates. This membrane is best recognized for having the benefits of epdm and pvc systems at a more economical cost. The following provides general descriptions of these two systems. The most common thermoplastic membranes are pvc polyvinyl chloride and tpo thermoplastic polyolefin.

Tpo membranes are a relatively new roof membrane and have seen several reformulations in the past decade. Since they are new long term performance is unknown at this time. The tpo membrane was first introduced to the roofing market in the early 1990 s as a more economical and efficient alternative that was thought to replace pvc roofing products. It maintains its integrity throughout a wide range of thermal expansion and contraction.

It is made from asphalt and a variety of rubber modifiers and solvents. Tpo roofing is usually installed mechanically attached or fully adhered systems. The most common thermoplastic roof membranes are pvc and tpo. Tpo is a single ply roofing system that consisting of a thermoplastic polyolefin membrane.

Thermoplastic membranes such as pvc or tpo are generally sealed by heat welding with hot air or by using solvents to weld the sheets together. An example of thermoset membranes includes ethylene propylene diene monomer epdm one of the most widely used roofing systems. Unlike sarnafil which is formulated to perform above and beyond the industry standard sikaplan is formulated to the industry standard like the rest of the thermoplastic roofing membranes on the market. An asphalt roof costs between 8 and 10 per square foot installed.

Tpo thermoplastic polyolefin is a single ply reflecting roofing material or membrane made out of ethylene propylene rubber and polypropylene polymerized together.
