About SPF Foam



Flexible, seamless, lightweight roofing system that's truly leak-proof!

SPF is a closed cell roofing material formed by the combination of two liquid components. When these two materials meet in the mixing gun they immediately expand 20-30 times their volume, forming a rigid polyurethane foam (PUF). The roof is sprayed to the desired thickness, (usually 1-2 inches) The entire roof is sprayed to form a seamless monolithic surface including flashing, penetrations and parapet walls. This process eliminates seams and cold joints, the source of major leaks and thermal shorts. The system provides a durable waterproof covering that bonds tightly to nearly any properly prepared surface.

Sprayed Polyurethane Foam (SPF) has been used as a roofing and insulation material for more than 30 years. During this time, SPF systems have proven themselves through comprehensive, independent studies to be dependable, long lasting, and very affordable. Today there are foam roofs that have been in place for more than 30 years, and by all appearances they should be able to last indefinitely.

Sprayed Polyurethane Foam has an initial R-value of 7.14 per inch thickness, enabling it to provide more thermal resistance with less material than any other type of roofing insulation.

Sprayed Polyurethane Foam is lightweight Ė about 8 ounces per square foot Ė and can be
applied over most existing roof surfaces without exceeding the structural load capacity. Yet itís amazingly strong, easily withstanding foot traffic and other weight requirements. Since it can be applied directly over asphalt, shingles, built up roofs, clay, concrete, metal and wood there is rarely a need for tear-off, reducing the amount of time, disruption to the business and even reducing the debris in landfills.

Sprayed Polyurethane Foam has to be protected from exposure to the sunís ultra-violet radiation and moisture. This is where the Pella Roofing & Insulation Elastromeric coatings help protect and seal the foam from any damage
