PVC is considered to be a general purpose plastic. However, when PVC is compared to other similar plastics that only have carbon and hydrogen atoms in their molecular structure, it has significantly different attributes as it pertains to its performance and functions. One such attribute is chemical stablity — a common feature among substances containing halogens, such as chlorine and fluorine. This applies to PVC resins which furthermore possess fire retarding properties, durability, and oil/chemical resistance.1
In the roofing & construction industry, these properties make PVC membranes a superior product selection when it comes to safety, longevity, and resistance to substances/conditions that normally weaken or destroy other types of roofing materials prematurely. These properties include: an inherent fire retarding capability, high resistance to atmospheric oxidation, high resistance to organic solvents, mechanical stability, ease of processing/molding during manufacturing, and a highly flexible molecular structure that allows PVC to integrate with plasticisers, modifiers, and coloring agents.
IB Roof Systems took note of PVC's potential back in 1978 by becoming one of the first providers of PVC membranes in North America. IB Roof Systems has grown into one of the most trusted and leading providers of PVC membranes, and we strive to provide our customers with top quality products that outperform competing materials while amplifying a building's safety, performance, and environmental impact.
