Save Money by Increasing Attic Insulation in Raleigh
Having the proper amount of insulation in your attic can make your Raleigh home more comfortable all year long. Higher energy efficiency could also help you save money on utility costs.
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. don’t have enough insulation. If every home in the country was suitably insulated to current building code, the Boston University School of Public Health determined 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 assess existing insulation to determine if you have a sufficient amount in your attic. If it’s lower than 7” deep, your home is underinsulated. In Raleigh, 16-18” deep is recommended.
Additionally, if your home is more than 10 years old, you’ll likely need deeper insulation.
Building up 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 lessen 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 uses 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 comprehensive barrier against air, vapor and water.
Open-cell foam expands when applied, filling cracks and other spaces that are hard to get to. It’s best for obstructing air but isn’t completely waterproof.
Both types of spray foam insulation may even help absorb noise.
Loose Fill and Batt Insulation
Loose fill insulation is blown in using special machinery, while batt insulation is rolls that can be trimmed to fit. Insulating material can contain fiberglass, cellulose, mineral wool and cotton.
Insulation is graded for its resistance to heat flow. This is also called the R-value. Particular levels are recommended based on where you live.
