TPO which is short for thermoplastic olefin, is a single-layer roofing membrane and one of the most energy-efficient roofing solutions in the world today. It combines the advantages of PVC and EPDM roofing systems without their shortcomings or extra costs. For instance, it has the heat-welding properties of PVC and the UV resistance and insulative feature of EPDM.
Compared to PVC roofing products, TPO is more energy-efficient and less expensive. It is made from thermoplastic polyolefin membranes and used as a single-ply roofing solution. However, the membrane consists of three layers which are:
Some of the fillers used for the manufacturing of TPO include talc, wollastonite, carbon fiber, Metal Oxy Sulfate, and fiberglass. EPR and EPDM are rubber materials that are also used for the manufacturing of TPO.
The fact that TPO is an inexpensive roofing solution makes it a popular choice for residential and commercial roofing projects. Despite its reasonable price, TPO still comes with the useful features of PVC such as seams that can be welded easily and its energy efficiency.
The appearance of TPO roofing materials looks stunning on different structures ranging from residential to commercial and industrial buildings. The most common colors of TPO roofs are white, and darker shades ranging all the way to black. The best part is that irrespective of the color option you select, TPO still efficiently reflects the sunlight and remains very energy-efficient. TPO roofs combine UV resistance with a certified cooling effect.
TPO roofs aren’t prone to mold growth, tears, punctures, and easy dirt accumulations. The membrane is highly flexible, giving room for movements of the building. This property allows TPO to manage the thermal expansion and contraction of buildings more efficiently than other single-ply roofing materials.
The structure of the TPO roofing membrane that is wide and lightweight makes the installation procedure less stressful and seamless. Therefore, the cost of installing TPO is relatively lower compared to other roofing solutions.
Homes that are roofed with TPO enjoy the energy-efficient features of this roofing material. In essence, such homes can make savings in the energy expended in cooling the home interiors. They also play a role in reducing the carbon footprint.
The white reflective surface of TPO surpasses EPA’s ENERGY STAR requirements. The tan and grey TPO roofing membranes are listed with the Cool Roof Rating Council. In essence, TPO roofs help keep your home interior fresh on hot days and decrease your air-conditioning.
