Does My Home Have Enough Attic Insulation?
You can check existing insulation to determine if you have enough in your attic. If it’s lower than 7” deep, your Livermore home lacks enough insulation. 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 Livermore home.
Strengthening your insulation levels could positively change 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.

Types of Attic Insulation
There are three types of attic insulation—spray foam, loose fill and batt.
Foam Insulation
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 out when applied, filling cracks and other hard-to-reach spaces. It’s best for blocking air but isn’t completely waterproof.
Both types of spray foam insulation may even help block noise.
Loose Fill and Batt Insulation for Attics
Loose fill insulation is blown in using specialized machinery, while batt insulation is rolls that can be portioned to fit. Insulating material can contain fiberglass, cellulose, mineral wool and cotton.
Insulation is rated for its resistance to heat flow. This is also called the R-value. Certain levels are recommended based on where you live.
