The use of thermoplastic olefin (TPO) is being increasingly used in the commercial and private flat roof industries. This popular roofing system is currently the fastest growing segment in the flat roof market. When compared to PVC and EPDM roofs, TPO roofing in Chicago is less expensive than PVC roofing and offers the same benefits of both of these types.
TPO roofing is made from three plastic layers, which are a thermoplastic polyolefin top, polyester fabric center (or “scrim) and polymer base. Specialized technology combines them to form one membrane. Frequently, fiberglass, carbon filler, talc or other type of usable material gets added for some extra filler. TPO is available in various different color options, including black, shades of grey and white. The most energy efficient color is white, and therefore the most popular. It improves consistency of the air conditioning temperature, creates a cooler roof and provides optimal UV ray reflection. In comes in different thicknesses, which are measured in mils, with 45 and 60 mils being the most common, and the highest durability being offered by the thickest option.
TPO is built for its ability to be recycled, cost, durability and energy efficiency. It is a smart roofing option choice. It is designed to promote longevity of the physical structure, efficient, and reflect UV rays for reducing heating inside the building and on the roof. TPO is also resistant to such damaging materials as debris, dirt, bacteria and algae, which makes it even more durable. It is comprised of strong seams that are welded together. From an environmental standpoint, TPO is considered to be a kind of green roofing. Chlorine-free polymer is used to form it (since chlorine is dangers for the environment), and it is totally and completely recyclable, and frequently reused for making new roof membranes.
When considering or buying a TOP roof system, there are a couple of things that you need to consider. They include durability, energy efficiency and manufacturing quality. When considering membranes, remember that some TPO manufacturers only have been in business for a couple of years. The best TPO manufacturers will have been in business making TPO for 10 years at least, and be up to ASTM roofing standards. When it comes to energy efficiency, keep in mind that light grey or white colors are the most energy efficient and provide the maximum about of temperature cooling as well. In terms of durability, the thicker membranes, like those that have strong seams and are 60 mil thick, will provide you with the most reliable and weather protected roof, and will ensure that your building is kept well maintained.
