Does My Home Have Enough Attic Insulation?
You can measure existing insulation to determine if you have enough in your attic. If it’s less than 7” deep, your West Chester home is underinsulated. Depending on where you live, between 13-14″ of insulation to as much as as 16-18″ of insulation will be what’s recommended. In addition, if your home is older than 10 years, you’ll most likely need more attic insulation in your West Chester home.
Strengthening your insulation levels could positively affect your energy bills, saving you up to 20 percent.** It can provide a vapor barrier against humidity, minimize air leaks, and may limit wear and tear on your HVAC system.
**Savings may vary.
Types of Attic Insulation
There are three types of attic insulation—spray foam, loose fill and batt.
Foam Insulation
Spray foam insulation mixes liquids that harden into a foam on contact. Closed- or open-cell applications can be used in attics.
Closed-cell foam provides the most insulation. It also creates a comprehensive barrier against air, vapor and water.
Open-cell foam expands when applied, collecting in 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 dampen noise.
Loose Fill and Batt Insulation for Attics
Loose fill insulation is installed using specialized 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. Different levels are ideal based on where you live.
