Somewhat similar to PVC, TPO membranes are made from (ThermoPlastic Olefin) or polyolefin applied over a reinforcing scrim. White is again the color most commonly used as it offers excellent solar reflectivity. Both PVC and TPO are highly tear resistant and TPO laps are also welded together using hot air.

TPO Roofing Systems combine the long-term durability rubber provides with the security of hot air welded seams. TPO’s advantages include:

• TPO roofing systems are the most environmentally friendly of the single-ply systems.

• They produce no dioxins or chlorine.

• Membranes come in varying thicknesses to meet your specific requirements and are available in varying roll widths.
