Advantages of SPF (Sprayed Polyurethane Foam)
Sprayed Foam insulation reduces energy use in buildings beyond its stated R-value because SPF (closed cell):
- Provides a solid continuous vapor barrier and air-tight seal (no cracks or leaks).
- Prevents moisture infiltration through air leakage. On roofs it seals water leakage.
- Minimizes dew point problems and condensation by creating an air-tight barrier.
- Can eliminate mold & mildew from penetrating the envelope of your living environment.
- Resists heat movement in all directions.
- Provides reliable performance under varying conditions. Does not break down (i.e., sustainable).
- It has the highest exponential R-value of all insulations. FOAM has a 92% Efficiency Rating (ER), 1 inch equivalent to R-20.09! 2 inches = R- 40.18 ! 3.5 inches = R- 63.7 according the rating by the U.S. Dept. of Energy! ER boost based on RED factors:
Sprayed Foam is the
tightest air sealer.
Foam for metal buildings.
Foam where nothing else will work.
ONLY FOAM can INCREASE the insulation rating by reducing all 6 causes of heat transfer.
Cellulose addresses # 2 & # 3 in ways that fiberglass cannot.
3.5 inches of Fiberglass has 32% efficiency with only R-11.2
Only SPF foam addresses all 6 in ways no other insulation can!
As the most effective type of insulation, closed-cell Sprayed Polyurethane FOAM (SPF) is a solid, rigid, waterproof, and seamless plastic after it cures (in only a few seconds). It is impervious to liquid or gas penetration. The History Channel describes closed-cell polyurethane foam insulation as one of the "modern marvels" of modern chemistry: It not only insulates, but also dramatically adds to the strength and structural integrity of any building material. SPF is sustainable: Unlike other materials that have a limited life expectancy, SPF has an indefinite life when maintained properly. (Health: The new generation SPF foam, properly installed, does not "off-gas" chemicals, nor contain formaldehyde.) OPEN-CELL foam (below) for sound-proofing & insulation. CLOSED-CELL (below) and High- Density foam insulation for waterproofing, thermal barriers and increased strength and structural integrity.

Oak Ridge National Laboratory research shows that “perfectly installed” fiberglass batts lose 11% of their labeled
R-Value, and that “commonly installed” fiberglass batts lose 28% of their labeled R-value. This study confirms tests conducted 20 years ago by fiberglass manufacturers, and reveals the surprisingly large disparity between the labeled R-value and the installed R-value of fiberglass batts. The point is that R-Value is not the best measure of insulation and that fiberglass is the worst kind of insulation.
