Thermoplastic polyolefin (TPO) roofing is the not-so-new system in the world of commercial and residential roofing. It has been around for decades yet has only recently found its niche in the industry. All American Roofing shares a decade by decade look at the history of thermoplastic polyolefins (TPO) as used in roofing.
The Seventies: Necessity is the Mother of Invention
At this time, there were only two types of flexible sheet that were being used: EPDM and PVC. The problem with those two flexible sheet types, however, is that the former was not weldable while the latter contained liquid plasticizers. It wasn’t long before thermoplastic polyolefins were created.
The Eighties: The Age of Discovery
TPO was first used in the automotive industry for the purpose of protecting exterior surfaces in addition to being wire covers. Then several companies, from Versico to JPS Elastomerics, started launching TPO roofing membranes as a viable roofing material.
The Nineties: The Age of Innovation and Development
Concerns regarding the use of fire-resistant materials in TPO, which affected UV resistance, prompted innovation. Manufacturers began to alter their formulations and added magnesium hydroxide as the fire-resistant component. This remains the case until today.
The New Millennium: Here and Now
Lyondell-Basell, the company which supplied TPO from all those years ago, is still the company that supplies the roofing industry today. Thanks to its fire and UV-resistant properties, TPO is a natural material for roofing purposes. Since the turn of the century, the sales numbers of TPO membranes have grown annually–at no less than a double-digit pace.
