Closed cell spray foam insulation is best if you need spray foam insulation installed in a place where moisture or water vapor are a concern. For instance, installing a 20 seer heat pump, Lapolla Foam-Lok spray foam and single pane windows would have weak link in the envelope because of the inefficient windows. spray foam load calculation in an open space My new build is an odd space -- I'm sure there must be some program to factor when using spray foam .. and not just R value. Spray Foam Calculator. Spray foam insulation or spray polyurethane foam (SPF) is an alternative to traditional building insulation such as fiberglass.A two-component mixture composed of isocyanate and polyol resin comes together at the tip of a gun, and forms an expanding foam that is sprayed onto roof tiles, concrete slabs, into wall cavities, or through holes drilled in into a cavity of a finished wall. Units: U.S. CAR=0.1 pgm/ft 2 3. ft. Add that total to 1,000 sq. Multiply this total by the height of your walls Products with a higher R-value provide greater insulation. C. Polyurethane's low weight (around 2.5 to 6 pounds per cubic foot) and its expansion abilities transfer very little weight to the underlying soil.
