SPF is a closed-cell roofing material formed by combining
two liquid components. When these two materials meet in the mixing gun,
they expand 20 to 30 times their volume immediately, forming rigid
polyurethane foam. This is sprayed on the entire roof to the desired
thickness, usually 1-2 inches, to form a seamless monolithic surface
including flashing, penetrations and parapet walls.
SPF has an initial R-value of 7.14 per inch
thickness. This provides more thermal resistance
with less material than any other type of roofing
insulation. This eliminates seams and cold
joints, the primary source of major leaks, and
provides a durable waterproof covering that bonds
tightly to nearly any properly prepared surface.
The lightweight application (about 8 ounces per square foot) can be applied over most existing roof structures. Since it can be applied directly over asphalt, shingles, built up roofs, clay, concrete, metal and wood there is little to no need for tear-off, reducing the amount of time, disruption to the business.
