Why Is PVC Used on Commercial Roofs?
PVC is manufactured in reinforced sheets that are installed across a low-slope roofRoof Types - Low-slope roofs (flat roofs) are a type of roof system with less than a 3:12 pitch, most commonly found on commercial and industrial buildings. More and heat-welded, creating a continuous waterproof surface. Like TPOPrimary Roof Covering - TPO (thermoplastic polyolefin) is a white roof covering used on flat (low slope) roofs, commonly installed on commercial buildings to create a continuous waterproof surface. More, PVC is a thermoplastic, meaning the material can be softened with heat and welded together rather than relying on tape or adhesive at its seams.
PVC is commonly used for restaurants, food-processing facilities, airports, and industrial buildings because many PVC membranes resist grease, animal fats, fuels, and other chemicals that may reach the roof through exhaust. Restaurants are a particularly common use because kitchen exhaust will continually deposit grease and oil onto the roof around vents.
Different PVC formulations provide different levels of chemical resistance. For buildings with especially demanding conditions, KEEPrimary Roof Covering – KEE (ketone ethylene ester) is a solid, flexible polymer used in some low-slope roof membranes to help maintain flexibility and resist chemical and weather exposure. More may be incorporated into the membranePrimary Roof Covering - A single-ply membrane is a roof covering that uses one continuous layer of material to waterproof low-slope roofs. More to improve chemical resistance and help the material retain flexibility as it ages.
