Save Money by Increasing Attic Insulation in Charleston
Having the right amount of insulation in your attic can make your Charleston home more pleasant all year long. Higher energy efficiency could also help you save money on heating and cooling costs.
Do you have the right 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 properly insulated to modern 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 annually!
Does My Home Have Enough Insulation?
You can assess existing insulation to determine if you have enough in your attic. If it’s less than 7” deep, your home is lacks enough insulation. In Charleston, 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 impact your energy bills, saving you up to 20 percent.** It can provide a vapor barrier against humidity, stop air leaks and may limit wear and tear on your HVAC system.
Types of Attic Insulation
There are three kinds of attic insulation—spray foam, loose fill and batt.
Spray foam insulation uses liquids that expand 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 an extensive barrier against air, vapor and water.
Open-cell foam spreads when applied, stopping cracks and other inaccessible spaces. It’s best for stopping 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 trimmed to fit. Insulating material can include fiberglass, cellulose, mineral wool and cotton.
Insulation is ranked for its resistance to heat flow. This is also called the R-value. Certain levels are recommended based on where you live.
