Does your home always seem to be drafty and hard to keep comfortable? If it’s more than a decade or two old, there’s a good chance that it’s under-insulated, which can mean significantly higher heating costs in the winter and cooling costs in the summer.
But how much insulation do you need? Recommended insulation levels vary by region, with higher R-values needed for colder climates.
An insulation’s R-value describes its resistance to the flow of heat. A material with a lower R-value will let more heat bleed through faster than an insulation with a higher R-value.
The goal is to slow down the amount of heat transferred through the insulation to keep your home warmer in winter and cooler in summer. This reduces the work your HVAC system has to do to keep your home comfortable and lowers your energy costs.
An R-value reflects resistance to heat loss across an insulating material over a given period of time. Different materials can be compared by calculating their R-value per inch. Wood has an R-value of 1, so a 3-inch board would be rated at R-3.
Spray foam insulation with a rating of R-5 per inch would have a total R-value of R-15 when installed at a 3-inch thickness. Fiberglass batts rated at R-3.7 per inch would have a total value of R-11.1 at a 3-inch thickness.
Green Bay and Fox Cities Wisconsin, area are in Climate Zone 6, so the insulation levels recommended by the U.S. Department of Energy are as follows for common areas of the home:
In many cases, more insulation can be added over the top of existing insulation to bring your home up to the recommended levels.
R-value can change over time, as well. Blown-in cellulose or fiberglass can settle, losing some of its R-value, and fiberglass batts will also decrease if they’re compressed.
