How Much Insulation Do I Need?
The answer to this question will depend a lot on where you live. The federal government has recommended insulation levels according to geographical zones based on the normal seasonal weather patterns you're experiencing in that given area.
How Long Will It Take to Recoup My Investment?
This is another one that depends on where you live. However, in most cases, the direct savings from using less energy is equal to the amount spent on insulation within 2-4 years. This doesn't include tax breaks or property benefits.
What Does R-Value Stand For?
R-value is how the industry describes the resistance to heat flow of any given building or material. The higher the R-value, the greater the insulating power, and the greater your potential energy savings.
