What does insulation R-value mean?

According to consumer.ftc.gov, R-value means resistance to heat flow. The higher the R-value, the greater the insulating power. In theory, all insulation with the same R-value should insulate equally. Unfortunately, in reality, that is not the way it works out. One of the biggest factors in maintaining the R-value is the way the insulation is installed. When installed perfectly, it will retain most of its R-value. However, common installations of fiberglass and cellulose show about a 50% drop in R-value when installed. An easy example to think about is a conventional attic. When its hot outside, let's say 95-100°F, your attic gets even hotter due to the radiant heat build up and hot outside air infiltration as ventilation. With typical fiberglass, cellulose, or blown insulation your attic will still get to 120-140°F making your living area/conditioned space below have to work much harder to combat the large temperature difference. So, for example, if your living area is 75°F and your vented attic is 135°F, that's a 50°F temperature difference! Adding spray foam to the underside of the roof deck, between the rafters and creating an unvented attic will not only lower this big temperature difference to approx. 10-15°F, but will allow your AC equipment to run less and not have to work so hard against your attic.

How is spray foam insulation added to a home?

ThermoSeal Spray Foam is sprayed in place in wall cavities, between the roof rafters or ceiling joists, and between floor joists in a raised home by an authorized ThermoSeal professional contractor. ThermoSeal insulation can be sprayed after electrical and plumbing services are in place. Spray foam insulation is applied as a liquid and then quickly expands in-place finding and filling and sealing all cracks, crevices, and voids where air is lost and infiltration is most common which exists within every building envelope. This sealing provides your home a complete air seal which other insulations cannot do. The Department of US energy sites that 40% of a buildings energy is lost by air infiltration alone. ThermoSeal blocks 100% of all air infiltration making it the most effective insulation money can buy.

Compare spray foam insulation vs fiberglass

First off there really is no comparison. Spray foam insulation creates a complete air-tight seal preventing air drafts and mold growth. On the other hand, fiberglass is not air-impermiable. This allows air to infiltrate the fiberglass insulation making it only an air filter and not an air barrier. Have you looked to see what's growing in your walls? We see mold growing all the time on fiberglass and cellulose insulated homes. There have been numerous independent studies that show fiberglass loses more than half of its R-value after being installed. So why allow your home to be at risk as well as put up with an insulation product that doesn't maintain half its R-value?
