How much does a bag of blown insulation cover?

On average, a 19-pound bag of blown-in cellulose insulation also costs about $30, but it covers about one-fourth of the amount of space as fiberglass loose fill insulation. Cellulose is a more natural alternative to fiberglass, but it's generally more expensive.

Is spray insulation worth the cost?

The EPA's Energy Star Association has shown that monthly energy bills can be cut by up to 20% when air leaks are sealed and efficient insulation is installed. The initial cost of spray foam insulation is well worth the investment, when factoring in the overall savings that will be headed your way over the long term.

What is the R value of 8 inches of cellulose?

Cellulose is not unusual in this regard. Like many insulation materials, it provides an R-value of approximately R-3.5 per inch of thickness. But, air leakage through cracks, voids, and gaps is important, responsible for approximately one-third of an average home's heat loss.

Can you put too much insulation in attic?

Without proper ventilation, a home can build up too much moisture, especially in the attic (warm air rises), which can cause mold problems and, overall, lower indoor air quality. This is not to say that if you have mold in your home, too much insulation is the culprit.

How do I calculate how much insulation I need?

Measure the height and width of any windows or doors in the wall. Multiply the measurements to find the area of each window or door, and subtract them from the total square footage of the wall. This gives you the square footage of insulation you need for that wall.

How do I calculate the R value in my attic?

To find the R-value of the existing insulation in your attic, multiply the number of inches of insulation by the R-value for your particular type.

Cold Climates (R-49 to R-60):

  • Fiberglass (blown): 19” – 25”
  • Fiberglass (batts): 14” – 19”
  • Cellulose (blown): 14” – 18”
  • Rock Wool (loose): 17” – 25”
  • Foam (sprayed): 7” – 15”
  • What is a good R value for exterior walls?

    Typical recommendations for exterior walls are R-13 to R-23, while R-30, R-38 and R-49 are common for ceilings and attic spaces. See the Department of Energy's (DOE) ranges for recommended levels of insulation below.

    How many inches is r60 insulation?
