Thermoplastic Single Ply Membrane Roofing

In the building trades the acronym tpo stands for thermoplastic polyolefin a material originally developed for pond liners and used extensively for roofing since 1989.

Thermoplastic single ply membrane roofing.

What are single ply membranes. Thermoplastic olefin tpo tpo membranes are produced by calendering with lamination extrusion with lamination or extrusion coating techniques. Short for thermoplastic polyolefin tpo is a single ply roofing membrane that offers excellent performance at a cost effective price. Heat welded seams provide superior strength.

Two of the most commonly used thermoplastic single ply membranes are pvc and tpo both of them plastic based materials. Thermoplastic polyolefin tpo single ply roofing membranes are among the fastest growing commercial roofing products and have gained praise across the industry for their many performance and installation advantages. It s a single ply membrane made from a polymerized combination of polypropylene and ethylene propylene rubber that can be attached to a roof with adhesive or with mechanical fasteners. Since there is only one weathertight layer it is critical that the seams transitions and penetrations are properly installed to prevent leaks.

Referred as elastomeric roofing systems these membranes are available in form of sheets. Thermoplastic polyolefin is a single ply roofing membrane that is one of the fastest growing commercial roofing systems on the market. These systems are generally categorized as thermoset and thermoplastic membranes. Thermoplastic and thermoset single ply membrane roofs are installed in large sheets that are joined together to create one continuous membrane.

Tpo sheets are a blend of polypropylene and ethylene propylene polymers and usually are reinforced with polyester. Thermoplastic membranes are usually manufactured to include a reinforcement layer normally polyester or fiberglass that provides additional strength and stability. This membrane is composed of three layers. Thermoplastic polyolefin compounded top ply.

Tpo s long term heat uv and natural fungal resistance plus flexibility without need for plasticizers also make tpo a reliable low slope roofing system. Tpo roofing systems are made up of a single layer of synthetics and reinforcing scrim that can be used to cover flat roofs. Tpo is a single ply roofing system that consisting of a thermoplastic polyolefin membrane. Polyester reinforced fabric center scrim.
