Thermoplastic Polyolefin (TPO)
Thermoplastic Polyolefin (TPO) is a single-ply reflective roofing membrane made from polyprophylene and ethylene-propylene rubber polymerized together. TPO can be installed either fully adhered, mechanically attached, fleeceback adhered, or as a self-adhering sheet, with the seams of the roofing system sealed with liquid adhesives or welded together. The first sheet of TPO roofing membrane was installed in 1989 and since then millions of square meters of TPO has been installed worldwide. TPO membranes commonly are white.
TPO membranes are produced by calendaring with lamination, extrusion with lamination, or extrusion-coating techniques. TPO sheets are a blend of polypropylene and ethylene propylene polymers and usually are reinforced with polyester. TPO sheets contain colorant, flame retardants, UV absorbers and other proprietary substances to achieve desired physical properties.
Benefits: Provides long-term durability and the heat welding process provides maximum security
- Common pigmentation is white which creates a reflective surface that will reduce building cooling cost
- Most environmentally friendly of the single-ply systems
- TPO produces no dioxins or chlorine
Membranes can be made in varying thicknesses and roll lengths
- Sheet widths range from 6 feet to 12 feet wide
- Sheets are typically 40 mils to 100 mils thick
Warranty Capabilities: 5-30 Years, 55-125 MPH
