Thermoplastic Polyolefin Roofing Membranes

Thermoplastic Polyolefin Roofing Membranes

In roofing industry, you will find that there is not just the common metal and concrete roof available, if you just keep yourself up-to-date with the market trends today. Other alternatives like the plastic roofing which is a product of recycled materials and one of the latest and the newest in flat roofing is available in the market today, as Roofers have reinvented and redesigned the materials. It is called Thermoplastic Polyolefin Roofing Membranes or the TPO.

With combination of ethylene propylene diene terpolymer (EPDM) rubber and PVC, the TPO roofing material is considered a “new generation” roofing membrane. TPO membrane has the basic characteristics that are taken from the mixture of the two flexible membranes EPDM and PVC. Long-term resistance to changing weather, tear and puncture resistance, temperature change flexibility, and chemical resistance are included in the TPO characteristics.

TPO consists of at least 20% rubber and despite its being a single-ply membrane; it is originally used for automotive applications. The structural deck, the thermal insulation barrier in the middle, and a waterproofing skin are the three basic components of a roofing system which TPO has. It can also be manufactured in a variety of colors, including black, just like other types of roofing materials. TPO roofing material’s lifespan cannot be determined yet since it is relatively new to the market.

Several benefits and advantages over other roofing materials are provided by TPO roofing material. The previously mentioned attributes are a few of the benefits which were taken from the combination of the two flexible membranes. That TPO is heat-resistant and remains heat-wieldable throughout its entire lifespan has become the signature of it. To avoid it from fading, it contains UV protection. TPO is also made to endure changing weather and climactic conditions aside from its resistance to heat. It keeps the interior of the building cool, making it an energy-saver during hot weather like summer.

Because of its polymer and rubber content, a typical TPO roofing material has good insulation performance so it does not conduct sound, electricity, or heat. In the market today, this type of material is one of the most recyclable and is very much environment friendly. The thermal reaction of molecules on the materials causes it not to separate as compared to other compositions that are melted together and ground up since TPO is an alloy, scientifically speaking. Most TPO sheets can feel more firm and rigid while some of them may be soft and flexible, which can help a lot in the installation process. Roofing contractors, engineers, architects, and even homeowners are attracted by these attributes and they currently choose it for their roofing system. TPO can be best used particularly for flat-roofed system and generally for commercial applications.
