WHAT INNOVATIVE ENERGY SAVING TECHNIQUES DOES SPRAY POLYURETHANE FOAM ALLOW? SEVERAL.
1. You won’t need house wrap with NCFI spray insulation. The air and moisture sealing effects of the spray polyurethane insulation are far superior to what house wraps can do. Don’t waste your money on house wrap if you are insulating with spray polyurethane.
2. You can encapsulate your entire exterior house shell with spray polyurethane. In effect, this creates conditioned space everywhere–including attics, basements, and crawl spaces. When ductwork is run through these areas, it is kept within conditioned space, substantially increasing the energy efficiency of your home. This reduces energy loss from recessed lights and drop ceilings while minimizing any chance of frozen pipes in colder climates.
3. Spray polyurethane insulation will conform to any size or shape cavity. Bay windows, oval windows, angled walls, sloped ceilings, or any other unusual framing designs can be well insulated and tightly sealed the same as the uniform spaced stud walls.
CAUTION: Do not try these insulation techniques with conventional glass fiber batts or blown-in cellulose.
