PVC (polyvinyl chloride) roofing systems are designed to be durable under the most extreme of weather or environmental conditions. As such, PVC roofing membranes are a logical choice for high performance, long lasting roofing products in the industrial/commercial space.
PVC roofing is one of the most popular thermoplastic roofing membranes. It is available in various thickness profiles. While the most common is 50 mils, PVC roofing can also be obtained in thicknesses of 40 mil and 80 mil. It is available in white, tan and gray colors.
PVC roofing systems are considerably reflective by design and are therefore ideal for commercial/industrial facilities such as airports or eateries that encounter grease, oil or other sorts of chemicals.
PVC roofing membranes, which are available in different thickness profiles and sizes, can be applied using any of the following three methods:
Mechanically attached: This process involves attaching the PVC roofing system to the deck with screws or other sorts of fasteners should the deck type necessitate using something other than screws.
Ballasted: This process involves placing the PVC roofing system on the roof surface loosely, while being secured only at the perimeter of the roof and around air conditioning equipment, pipes and other type of roof penetrations, before holding it in position using ballast.
Single ply fully adhered: This process involves attaching the PVC roofing system to the deck with a particular kind of adhesive.
Regardless of which of the three processes is used, the seams must be sealed using the same method, which involves utilizing a hot air welder.
PVC roofing membranes offer multiple benefits that make it a suitable option for commercial/industrial facilities. For example, the product is strong enough to be puncture resistant, it provides resistance to water, chemicals, acids, oils, and chemical fuels; and it is UV resistant as well.
