Q: What is R-value?
A: R-value is a measure of energy efficiency. The higher the R-value of the insulation, windows, and even a home's structure, the better the house is able to block the transfer of unwanted hot or cold air through walls and ceiling. Residents of homes with high R-values experience far less variation in temperature—and enjoy lower energy bills—by not having to run a furnace or air conditioner continuously to keep the house comfortable. That's high performance, That's sustainable, That saves you money!
