Keep It or Throw It: Should I Get Rid of Old Attic Insulation?

Having the correct amount of insulation in your attic doesn’t just keep your house comfortable. It can help you save a lot of money on your energy costs.

If you suspect your residence is among the 90% in the United States that doesn’t have adequate attic insulation, now is a fantastic time to install more. Having adequate insulation helps regulate your residence’s temperature and halt wintertime issues like ice dams, according to the Insulation Institute.

As you get ready to begin adding insulation to your attic, you may be wondering 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 present insulation is wet or damaged, you can often keep it. We suggest calling a pro who specializes in attic insulation in Cleveland, like Service Experts Heating & Air Conditioning. That way, you’ll know your attic insulation is added correctly and meets building code standards. Proper installation also means you’ll get max benefits for energy efficiency.

If your insulation resembles shiny pebbles or chips, stop prior to adding additional insulation. Vermiculite insulation was frequently installed in homes built prior to 1990. The EPA says you should assume it has asbestos, which can lead to cancer. Don’t touch it or disturb it and contact a pro who specializes in asbestos removal.

How Much Attic Insulation You Should Have

ENERGY STAR® advises attics should have at minimum 14” of insulation, which provides an R-value of 38. Attic insulation R-value gauges how well insulation can stop heat. If you have a home in a northern climate, up to 18” or an R-value of 49 is suggested.

R-value is also influenced by the type of insulation you use, its depth and how it’s put in. When you work with a company like Service Experts Heating & Air Conditioning, our specialists take all the guesswork out of R-values and how much insulation needs to be added.

What’s the Best Insulation for My Attic?

Service Experts Heating & Air Conditioning chooses the right 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 available in sheets cut to fit your attic and is built from fiberglass, mineral wool or cotton. Fiberglass is the most requested, because of its price, moisture resistance and fire resistance. Mineral wool is costlier, but provides excellent protection against fire, water and sound. Typically made from recycled jeans, cotton insulation is an earth-friendly choice that provides great performance.

Blown-In Attic Insulation

A distinct machine is used to put in blown-in attic insulation, which could contain fiberglass, cellulose, mineral wool or cotton. Cellulose is a good choice if you have a lot of small spaces to fill, such as around pipes, wiring or framing. While cellulose is competitively priced and fire resistant, you’ll also have to consider that it can hold on to moisture and flatten as time passes.

Spray Foam Attic Insulation

This liquid insulation converts to a hard foam on contact. It provides the strongest barrier against air, vapor and water. Spray foam attic insulation is fantastic for sealing cracks and other hard-to-get at locations. It’s highly long-lasting, doesn’t flatten and offers a natural sound barrier.
