Keep It or Throw It: Should I Take Out Outdated Attic Insulation?

Having the correct insulation thickness in your attic doesn’t just keep your house comfortable. It can help you save major money on your heating and cooling costs.

If you are concerned your residence is among the 90% in the United States that doesn’t have adequate attic insulation, now is a fantastic time to put in more. Having adequate insulation helps even out your house’s comfort and halt wintertime problems like ice dams, according to the Insulation Institute.

As you get ready to begin adding insulation to your attic, you might be considering if you need to do attic insulation removal. Not necessarily, and here’s why.

In Most Cases, You Can Keep Old Attic Insulation

Unless your current insulation is damp or damaged, you can often keep it. We advise partnering with a pro who specializes in attic insulation in Tempe, like Bob Brown Service Experts. That way, you’ll know your attic insulation is added accurately and meets building code standards. Accurate installation also means you’ll enjoy top benefits for energy efficiency.

If your insulation appears to be shiny pebbles or chips, stop before adding extra insulation. Vermiculite insulation was commonly installed in homes built before 1990. The EPA says you should presume it contains asbestos, which can cause cancer. Don’t touch it or disturb it and get in touch with a pro who specializes in asbestos removal.

How Much Attic Insulation You Should Add

ENERGY STAR® advises attics should have at the very least 14” of insulation, which provides an R-value of 38. Attic insulation R-value gauges how efficiently insulation can block heat. If you live in a northern climate, as deep as 18” or an R-value of 49 is recommended.

R-value is also affected by the kind of insulation you use, its depth and how it’s added. When you work with a pro like Bob Brown Service Experts, our Experts take all the guessing out of R-values and how much insulation needs to be added.

What’s the Best Insulation for My Attic?

Bob Brown Service Experts chooses the ideal insulation for your attic by including where you own your home, your budget and how much insulation you need to have. Here are the types of attic insulation we install.

Batt Attic Insulation

This kind of insulation is installed in sheets cut to fit your attic and is built from fiberglass, mineral wool or cotton. Fiberglass is the most popular, because of its price, moisture resistance and fire resistance. Mineral wool is pricier, but delivers excellent protection against fire, water and sound. Often made from recycled jeans, cotton insulation is an earth-friendly solution that delivers outstanding performance.

Blown-In Attic Insulation

A specialized machine is used to install blown-in attic insulation, which can include fiberglass, cellulose, mineral wool or cotton. Cellulose is a good option if you have a lot of little spaces to fill, like around pipes, wiring or framing. While cellulose is economical and fire resistant, you’ll also have to consider that it can retain moisture and settle over time.

Spray Foam Attic Insulation

This liquid insulation converts to a hard foam on contact. It gives the broadest barrier against air, vapor and water. Spray foam attic insulation is ideal for plugging cracks and other hard-to-get at areas. It’s extremely durable, doesn’t flatten and gives a natural sound wall.
