Quality TPO Roofing Materials for Commercial Use

Thermoplastic Olefin (TPO) membranes are produced by calendering with lamination, extrusion with lamination, or extrusion-coating techniques. TPO sheets are a blend of polypropylene and ethylene propylene polymers and are usually reinforced with polyester. TPO sheets contain colorant, flame retardants, UV absorbers, and other proprietary substances to achieve desired physical properties.

The sheet widths range from 6 feet to 12 feet wide and are typically 40 mils to 100 mils thick. The seams are sealed by heat welding with hot air. TPO membranes are available in white, light gray, and black.
