Understanding the Spray Polyurethane Foam (SPF) Application Process

When it comes to protecting your roof, Spray Polyurethane Foam (SPF) is the best choice available. One of the great attributes to an SPF cool roof is its ability to withstand even the most severe weather elements. With routine re-coatings, an SPF roof has a lifetime guarantee. So, how is a SPF roof installed?
Spray Polyurethane Foam is first applied in liquid format that can adhere to any roofing substrate. The liquid form of SPF is a combination of a polyol blend and isocyanate that rapidly bonds together upon contact. During application the SPF expands to almost twenty times its liquid density, creating a monolithic covering over any roofing surface.
The energy efficiency of SPF is a massive cost reducer for any commercial building. A standard SPF cool roofing solution can reduce HVAC costs by up to 30% per year! The airtight density of SPF creates a highly insulated covering that registers upwards of 6 R-Value in heat resistant indexes. Continued protection against ultraviolet (UV) radiation is made possible through a thin elastomeric coating that can be continuously reapplied to protect the base coat of SPF. Re-applications are recommended once every 10-15 years, which is a significant change from continual maintenance of other commercial cool roofing solutions.
