Save Money by Increasing Attic Insulation in Nashville
Having the right amount of insulation in your attic can make your Nashville home more pleasant throughout the year. Higher energy efficiency could also help you save money on utility expenses.
Do you have the correct amount of insulation? Probably not. A recent study by the North American Insulation Manufacturers Association determined 90 percent of homes in the U.S. are underinsulated. If every home in the country was appropriately insulated to current building code, the Boston University School of Public Health discovered it would slash electric consumption by 37 billion kilowatts. That’s enough electricity to power 3.4 million American homes each year!
Does My Home Have Enough Insulation?
You can assess existing insulation to learn if you have enough in your attic. If it’s shallower than 7” deep, your home is underinsulated. In Nashville, 16-18” deep is recommended.
Additionally, if your home is more than 10 years old, you’ll likely need more insulation.
Enhancing your insulation levels could positively change your energy bills, saving you up to 20 percent.** It can supply a vapor barrier against humidity, stop air leaks and may restrict wear and tear on your HVAC system.
Types of Attic Insulation
There are three varieties of attic insulation—spray foam, loose fill and batt.
Spray foam insulation combines liquids that change into a foam on contact. Closed- or open-cell applications can be used in attics.
Closed-cell foam provides the most insulation. It also offers a broad barrier against air, vapor and water.
Open-cell foam widens when applied, filling cracks and other hard-to-reach spaces. It’s best for blocking air but isn’t fully waterproof.
Both types of spray foam insulation may even help block noise.
Loose Fill and Batt Insulation
Loose fill insulation is blown in using special machinery, while batt insulation is rolls that can be cut to fit. Insulating material can involve fiberglass, cellulose, mineral wool and cotton.
Insulation is rated for its resistance to heat flow. This is also called the R-value. Particular levels are recommended based on where you live.
