Thermoplastic polyolefin, or better known as TPO, is the fastest-growing single ply roofing product for the commercial and industrial roofing industries. Fueling this growth is the increased use of TPO in southern climates, where reflective, energy-efficient and cool roof products are becoming the norm.
Single-ply membranes are generally categorized as either thermoplastic or thermoset. Thermoplastic materials can be repeatedly softened when heated and hardened when cooled. Thermoset materials solidify, or "set," irreversibly after heating. Single ply membranes commonly are referred to by their chemical acronyms, such as ethylene propylene diene terpolymer (EPDM).
Single-ply membranes may contain reinforcement layers. Common reinforcements for single ply membranes include polyester fabrics or scrims, glass fiber, or a felt or fleece backing. A finished sheet's thickness typically is referred to as mil thickness; 1 mil equals 0.001 inch. Common mil thicknesses for these sheet membranes range from 30 mils to 60 mils.
Single-ply membranes can be installed fully adhered, mechanically attached or held down with ballast. Most single-ply roof systems do not receive surfacings.
In many instances, a combination of attachment methods is used to secure a roof system.
For instance, an insulation board may be mechanically attached to the substrate with the roof membrane fully adhered to the insulation.
