Save Money by Increasing Attic Insulation in Knoxville
Having the right amount of insulation in your attic can make your Knoxville home more comfortable all year long. Better energy efficiency could also help you save money on heating and cooling expenses.
Do you have the correct amount of insulation? Probably not. A recent study by the North American Insulation Manufacturers Association found 90 percent of homes in the U.S. are underinsulated. If every home in the country was properly insulated to current building code, the Boston University School of Public Health found it would cut electric consumption by 37 billion kilowatts. That’s enough electricity to power 3.4 million American homes annually!
Does My Home Have Enough Insulation?
You can measure existing insulation to find out if you have enough in your attic. If it’s shallower than 7” deep, your home is doesn’t have enough insulation. In Knoxville, 16-18” deep is recommended.
Additionally, if your home is more than 10 years old, you’ll likely need increased insulation.
Strengthening your insulation levels could positively change your energy bills, saving you up to 20 percent.** It can be 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 turn into a foam on contact. Closed- or open-cell applications can be used in attics.
Closed-cell foam gives the most insulation. It also offers a broad barrier against air, vapor and water.
Open-cell foam widens when applied, filling cracks and other spaces that are hard to get to. It’s best for obstructing air but isn’t fully waterproof.
Both types of spray foam insulation may even help dampen 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 known as the R-value. Different levels are recommended based on where you live.
