How Much Insulation Do I Need?
The answer depends on a number of factors:
- Where you live — you’ll need a higher R-value if you live in the Northeast than if you live in Southern California.
- The age of your home (if your home is more than 10 years old, you likely need more)
- How your home is built — for example, is it a single-level or multi-level structure? Do you have cathedral ceilings? Is there a basement or is your home built on a slab?
- How you heat and cool your home — do you have a furnace, a central air conditioner, or a heat pump?
Recommended Levels of Insulation
NAIMA has prepared a map showing thermal recommendations based on both the U.S. Department of Energy’s recommendations and the most recent minimum International Energy Conservation Code levels. Click here for R-value recommendations for optimal energy savings and comfort.
Why Add More?
Adding fiber glass and rock and slag wool insulation above minimum requirements helps:
- Increase energy savings
- Provide greater noise control
- Control moisture which helps your house and roof last longer
Savings may vary, find out why in the seller's fact sheet on R-values. You can also access information about specific financial incentives being offered in your area. Simply select your state from the "Incentives" list on the right to learn more.
