In the past, sprayed polyurethane foam was considered only as an alternative to built-up roofing, Peritus commercial roofs now protect a wide range of buildings. Over time, through comprehensive independent studies, Peritus systems have proven to be dependable, long lasting and very affordable. Today there are foam roofs that have been in place for over 25 years and should be able to last indefinitely, with proper maintenance.
Sprayed Polyurethane Foam is a combination of isocyanate and polyol.
Because the foam is sprayed onto the roof as a liquid, it forms a single continuous membrane that is seamless and very stable. Peritus spray foam requires a clean surface for proper application. It must be dry and free of contaminants such as oil. The surface must also be properly fastened to the substrate in accordance with building code.
