Save Money by Increasing Attic Insulation in Birmingham
Having the right amount of insulation in your attic can make your Birmingham home cozier throughout the year. Better energy efficiency could also help you save money on utility bills.
Do you have the proper 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 enough in your attic. If it’s less than 7” deep, your home is underinsulated. In Birmingham, 13-14” deep16-18” deep is recommended.
Additionally, if your home is more than 10 years old, you’ll likely need increased insulation.
Building up your insulation levels could positively affect your energy bills, saving you up to 20 percent.** It can be 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 types of attic insulation—spray foam, loose fill and batt.
Spray foam insulation mixes liquids that expand 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 an extensive barrier against air, vapor and water.
Open-cell foam spreads when applied, stopping cracks and other inaccessible spaces. It’s best for obstructing air but isn’t completely 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 include fiberglass, cellulose, mineral wool and cotton.
Insulation is graded for its resistance to heat flow. This is also called the R-value. Different levels are recommended based on where you live.
