One of the materials that continues to transform the commercial and industrial roofing industry is thermoplastic single-ply membranes. For the past five years, they have been the fastest-growing segment of the U.S. roofing market.
Many roofing companies in Columbia, SC, install thermoplastic membranes because of their numerous benefits. The most common and frequently used thermoplastic roof membranes are PVC (polyvinyl chloride) and TPO (thermoplastic olefin). According to the Single Ply Roofing Industry, many thermoplastic membranes are designed with a reinforcement layer made of polyester or fiberglass to increase strength and stability.
PVC sheets are manufactured through calendering, spread coating or extruding, using stabilizers, fillers, biocides, pigments, PVC resin and other components. When formulated in sheets, they are reinforced with other additives in order to achieve flexibility and other desirable physical properties. PVC membranes are naturally fire- retardant, an important feature that appeals to many building owners. In addition, PVC has heavy-duty welded seams for outstanding durability and dimensional stability.
TPO is formed by calendering with lamination, extrusion with lamination, or extrusion-coating methods. According to the National Roofing Contractors Association, TPO is a mixture of polypropylene and ethylene propylene polymers that are normally combined with polyester.
TPO sheets have UV absorbers, colorant and other essential substances. Unlike PVC that has a natural fire retardant, TPO requires additives to enhance its resistance to fire. It is the second most popular thermoplastic membrane used by contractors and building owners.
These two thermoplastic single-ply membrane materials are both light in weight, resistant to elements and aesthetically pleasing. If you want a strong and durable commercial roofing system, you won’t go wrong with having PVC or TPO membranes installed.
