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. TPO membranes are white and highly-reflective, making them an excellent choice for those looking to reduce energy costs. In addition to being ENERGY STAR rated, TPO’s recyclability makes it an environmentally conscious system. Additionally, TPO roofs are durable and resist dirt, bacteria and debris build-up making them highly resistant to tears, punctures and impact damage.
PVC were first installed in the early 1960’s, PVC was the industry’s answer to the oil crisis, as it was the first membrane to contain half of the fossil fuels normally used in system manufacturing. Engineers discovered that adding additional solid plasticizers to the PVC membrane allowed for additional weatherability and flexibility, where the membrane alone would be more susceptible to seasonal climate changes. To this day, PVC membranes remain incredibly versatile, chemical resistant and are highly recommended for roof-over projects. They are available in a variety of colors, thicknesses, widths, and reinforcements, making them an excellent option for almost any roofing project.
