Homeowners are constantly urged to look for the best R-value* when evaluating insulation, but are rarely provided with a simple definition for what R-value* actually means.

R-value is a measure of heat resistance, which is determined by calculating how long it takes heat to move across materials. Insulation with a high R-value* and air-sealing properties, like spray foam, is recommended to prevent the home from rapidly losing heat and maintain comfortable temperatures all year round.

The amount of R-value needed for new insulation depends on climate and where the home is experiencing the most heat loss. Talk to a professional Icynene installer or check back here at icynene.com for more information about R-values* and spray foam insulation.

* R means resistance to heat flow. The higher the R-value, the greater the insulating power. Compare insulation R-values before you buy. There are other factors to consider. The amount of insulation you need depends mainly on the climate you live in. Also, your fuel savings from insulation will depend upon the climate, the type and size of your house, the amount of insulation already in your house, and your fuel use patterns and family size. If you buy too much insulation, it will cost you more than what you'll save on fuel. To get the marked R-value, it is essential that this insulation be installed properly.
