The advantages of Spray Polyurethane Foam (SPF) are numerous in terms of installation, performance, cost and longevity. SPF is a proven roof insulation currently in use on thousands of structures around the world.
Ideal for both new and replacement roofs, SPF is strong, flexible, and durable. It is versatile and easily applied to any roof type, whether it is flat, pitched, saw-toothed, or domed - even roofs with unusual slopes or configurations.
SPF offers a long list of benefits:
Seamless - SPF is seamless, monolithic, and self-flashing. Without the need for mechanical fasteners, seams and joints, it eliminates leaks, lowers installation costs, and reduces maintenance.
High R-value - Delivering the highest R-value per inch of any insulation product, SPF generates energy savings from lower heating and air conditioning costs, as well as contributing to LEED and Energy Star compliance.
Eliminates Flashing Leaks - Because it conforms to the substrate and is seamless, SPF is ideal for parapet walls, roof penetrations, and roof-mounted equipment, including vents, pipes, stacks, HVAC units, skylights and cooling towers.
Eliminates Ponding Water - Increased thickness of SPF in low areas and sloping the roof so that it drains properly solves the ponding problem and the additional load factor caused by water accumulation.
SPF is lightweight and usually costs less to install than other roof systems because it is often possible to apply it over and existing built-up roof without removing it. SPF roofs are easy to maintain and can last for years by renewing the roof’s protective silicone coating.
