What is Insulation R value?
Insulation is identified and labeled by R-value. “R” stands for resistance to heat flow. The higher the insulation R-value, the greater the insulating power. Insulation helps lower the cost of heating and cooling your home. In the winter, heat flows out; in the summer, heats flow in. A properly insulated home reduces that heat flow, so you don’t use as much energy to heat your home in the winter and cool it in the summer. Using less energy — or using energy more efficiently — could mean money in your pocket.
Do I Have Enough Insulation?
The Department of Energy estimates that 90% of US homes that are under-insulated. The amount of insulation recommended for your home will vary depending on a number of factors:
Where you live—Different climates require different insulation R-values. You will need a higher R-value of insulation if you live in the Northeast than if you live in Southern California.
Your home’s age—If your home is more than 10 year old, you likely need more insulation. There are many ways to retrofit a home with fiber glass and mineral wool insulation.
This map shows thermal recommended levels of insulation for various climate zones, based on recommendations from the U.S. Department of Energy (DOE) and the International Energy Conservation Code (IECC). The IECC is the model building code for the United States.
Effective insulation is also dependent on the type of materials and the proper installation. For more information on the different types of insulation, please read our blog - Which Type Is The Best Insulation For Your Home?
