What is TPO roofing material?

Before we dive into details, let us first define what is TPO roofing material? TPO stands for Thermoplastic Olefin. It is a single-ply thin roofing membrane that has unique features.

Due to its promising qualities, it is easily a top-of-mind choice when it comes to commercial or industrial constructions.

Since the 1980s, TPO roofing material is widely used by contractors and property owners. This is in response to the demand for a heat-reflective and energy efficient roofing system. This rubber-based membrane is produced by combining polypropylene and ethylene-propylene rubber. It is then blended with fiberglass filler, carbon fiber, and talc. These additives strengthen the base and help achieve its energy-saving properties.
