How much insulation is enough?
Insulation is measured in R-values. So, the higher the R-value, the better your walls, floors and ceilings will resist the transfer of heat. The amount of insulation you need depends on where you live. The U.S. Department of Energy (DOE) has established thermal (or R-value) recommendations for homes based on geographic zones.
Glass mineral wool residential building insulation products come in R-values ranging from R-8 to R-38 for glass mineral wool batts and rolls. Glass mineral wool blowing insulation can also be blown in an attic to nearly any R-value. You’ll find the R-value of your insulation printed on the package or bag it comes in. R-values are also printed on the facings of glass mineral wool batts and rolls.
As energy prices continue to rise, it pays to insulate—in more ways than one. Adding more insulation to your home or building can put money in your pocket.
In addition to lower utility bills, according to the EPA, for every $1 homeowners saved on annual fuel bills due to energy-efficient home improvements, their home’s value jumped by $20 or more.
Some local governments and many utility companies offer consumers cash incentives for simply upgrading their insulation. Find out about additional financial incentives in your area.
Lower Mortgage Payments
Planning on financing a new home? Consider an energy-efficient mortgage to help offset added construction costs due to energy improvements. The benefits include:
- Allowing borrowers to qualify for a larger mortgage as a result of energy savings
- Reduced monthly operating costs
- 100% of energy improvements can be financed—up to 15% of the value of the home for existing homes and 5% of the home’s value for new construction
