There are multiple factors involved in making spray foam insulation effective, but let’s begin with how the product is created. There are two main chemical compounds used to produce spray foam insulation, polyurethane and polyisocyanurate, although the latter is merely a more advanced form of the former. They are made from a chain of polymers [...]

Your home’s R-value may not be the first thing on your mind when you get up in the morning, or even the last when you go to bed at night. After all, it is a bit abstract and you may be more concerned with issues like paying your bills. But R-value—a measure of an insulation’s [...]

R-values give us a way to compare insulation types but at what cost? To get a real comparison you need to compare how they handle air, moisture, mold, noise, pests, smells, gas, and more.

Studies conducted by the Department of Energy’s Oak Ridge National Laboratories show that as outside temperatures get colder, the R-value of fiberglass insulation decreases. Using a full scale climate simulator, ORNL tested loose-fill fiberglass attic insulation rated at R-19 at a variety of temperatures. When outside temperatures dipped to -8°F, the R-19 insulation performed at [...]

The R-value myth has made us all use the same yardstick to compare very different type of insulations. When we do that, some insulation looks extremely expensive compared to other types of insulation. The same problem arises when comparing a Hyundai with a Lexus. If someone uses the standard of 4 wheels they can’t imagine [...]

Our nation’s fixation on R-value for our insulation is ridiculous. Large scale testing has proven that an air barrier is far more effective than any R number. Take this one experiment- where a duplex had half the attic insulated with R-20 Foam and the other half with R-30 batts. When the snow came, the roof [...]

Title 24, California’s Energy Commission is working on developing a method for inspectors to rate R-values for wall cavities. Because there are so many types and brands of insulation, it’s hard for inspectors to know what they are looking at. Until there is an easy way for them to tell, we encourage you to request [...]

When you see videos of Icynene, it looks impressive. The contractor blasts in one inch (messy process) and it bubbles up over the studs so they have to go back and shave it down. In comparison, Foam It Green Closed Cell Polyurethane Foam kits go on lightly like paint and cure to only 1 inch. [...]

Up to 40% of home heat loss can be attributed to an inadequate barrier system, which allows air to leak through holes, cracks and gaps in the thermal building envelope. Foam It Green will seal those areas, providing for a better air barrier system, critically important for economic moisture control, thermal transfer, and structural integrity.
