Proper attic insulation at the right depths in your attic not only keeps your house cool in summer and warm in winter, but can save you major money on your utility bills.
If you suspect that your home is among the roughly 90% of homes within the United States that lacks adequate attic insulation, look into installing more! Good attic insulation evens out your home’s internal temperature. In prepping to begin installing more attic installation, you might be wondering if you should rip out existing attic insulation. The answer? Not necessarily. Here’s why:
In Most Homes, You Can Keep Old Attic Insulation
Unless your existing insulation has been water damaged, you can usually keep it. We offer referrals to other professionals who specialize in attic insulation. By doing so, your new attic insulation will meet existing building code standards and ensure the maximum benefits of increased energy efficiency.
You should always call on an expert to inspect your insulation before working with it. Some vermiculite insulations in common use before 1990 contain asbestos, which can result in cancer. To be safe, presume that the insulation does contain asbestos, and avoid touching or disturbing it until an asbestos removal professional can inspect and remove it.
How Much Attic Insulation Should You Have?
ENERGY STAR® recommends that attics have at minimum 14” of insulation for an R-value of 38. Attic insulation R-values measure the effectiveness of insulation at separating indoor and outdoor heat. Due to Arizona’s hot climate, insulation depth as deep as 18” or an R-value of 49 is recommended.
The R-value may vary depending on the kind of insulation you have, its density, and how much insulation is added. By working with us, we will take all the guesswork out of R-values and the amount of insulation to be added. Call us today at (480) 531-8624 to learn more!
What is the Ideal Insulation for my attic?
We will help you determine the ideal insulation for your attic. We take into account the size and layout of your home, where you live, your budget, and how much insulation you should add.
Here are the types of attic insulation we use:
Batt Attic Insulation
Batt insulation comes in sheets that can be easily cut to fit your attic. It is made from fiberglass, mineral wool, or cotton. Fiberglass is the most popular material for price reasons, but it is also helpful because it is moisture-resistant. Mineral wool is a more expensive insulation, but delivers improved protection against fire damage, water damage, smoke, and noise. Made from recycled clothing, cotton insulation is an affordable, eco-friendly choice that offers additional thermal and noise-resistant performance improvements.
Blown-In Attic Insulation
Blown-in attic insulation is installed by the use of a specialized machine that blows in a blend of fiberglass, cellulose, mineral wool, or cotton. The blown-in mixture then hardens as insulation. The cellulose found in blown-in insulation is a great material for filling small areas around pipes, wiring, or framing, but it can take on moisture and flatten over time, reducing its thermal properties. In turn, blown-in insulation often requires reapplication every 10 years or so, depending on the amount of cellulose used.
Spray Foam Attic Insulation
Spray-foam insulation is liquid insulation that converts to a hard foam on contact and delivers the best thermal barrier against air, vapor, and water. Spray foam attic insulation is ideal for filling cracks and other nearly inaccessible locations. It is very tough, forms into a great sound wall, and does not compact over time, minimizing the need to reapply new insulation over time.
