Spray Polyurethane Foam
Spray Polyurethane Foam, more commonly referred to as SPF, is sprayed in a liquid form that expands into a foam, creating a solid layer as a roof or insulation. Polyurethane foam roofing is unique from roofing applications because of its ability to provide a seamless, monolithic layer of waterproof protection. Because it is applied through a spray, each application is concise and custom fit to even the most unique structures. Traditional roofing methods are manufactured off site and need to be cut, trimmed and glued together, leaving much room for error and leakage.
SPF has been used as a roofing and insulation material for well over 45 years. First pioneered for use by the military in the 1940s, the many uses of SPF have become more and more apparent ever since. Over the course of those years, foam roofing and insulation systems have proven themselves time and again by comprehensive, independent studies. SPF is dependable, long-lasting and affordable. Many of the foam roofs put in place during the early stages of innovation are still in place today, and appear to be in place indefinitely through proper maintenance.
How it works
SPF is the most cost-effective and sustainable roofing, insulation and waterproofing system available today. A combination of isocyanate and polyol, these two components are fed through a proportioner which heats then pumps the two separate components to the spray gun. Here they are mixed and sprayed onto the structure. Because it is sprayed onto the roof as a liquid, SPF forms a single continuous structure that is seamless and stable. SPF requires a clean surface for proper application. It must be dry, free of contaminants like oil, and properly fastened to the substrate in accordance with the proper building codes. A protective elastomeric top coat is required, which is typically sprayed on as well, but may be applied with hand or power rollers.
What are the advantages?
In case you can’t tell yet, we are passionate about this product. Foam roofing and insulation has many advantages over traditional roofing methods.
- Conserves energy
- Easy application
- Thermal insulation
- Air tight and moisture resistant
- Weather resilient
- Self flashing
- No tear off
- Easy maintenance
- Extended building life
With energy savings of 30% or more, the cost of an SPF roof is easily recovered within five years. When properly installed and maintained, SPF can last over 50 years! The longevity makes the financial plan of even the largest projects feasible, affordable and downright exciting.
One of the many reasons SPF’s use has become so widespread is its ability to deal with harsh climates and extreme weather conditions. An SPF roofing or insulation system can be used in any climate, and weathers the elements better than any alternative.
