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

Having the correct amount of insulation in your attic doesn’t only keep your house comfortable. It can help you save lots of money on your heating and cooling expenses.

If you think your house is among the 90% in the United States that doesn’t have ample attic insulation, now is a good time to add more. Having ample insulation helps regulate your residence’s temperature and prevent wintertime issues including ice dams, according to the Insulation Institute.

As you get ready to begin putting more insulation in your attic, you may be wondering if you need to do attic insulation removal. Not necessarily, and here’s why.

In Most Instances, You Can Keep Old Attic Insulation

Unless your present insulation is soggy or damaged, you can usually keep it. We recommend hiring a specialist who specializes in attic insulation in Alliance, like Service Experts Heating & Air Conditioning. That way, you’ll know your attic insulation is installed correctly and meets building code standards. Proper installation also means you’ll reap maximum benefits for energy efficiency.

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

How Much Attic Insulation You Should Have

ENERGY STAR® suggests attics should have at least 14” of insulation, which offers an R-value of 38. Attic insulation R-value gauges how well insulation can block heat. If you live 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 install, its density and how it’s added. When you work with a pro like Service Experts Heating & Air Conditioning, our Experts take all the guesswork out of R-values and how much insulation needs to be put in.

What’s the Best Insulation for My Attic?

Service Experts Heating & Air Conditioning figures out the best insulation for your attic by taking into account where you reside, your budget and how much insulation you need to install. Here are the types of attic insulation we use.

Batt Attic Insulation

This type of insulation is installed in sheets trimmed to fit your attic and is built from fiberglass, mineral wool or cotton. Fiberglass is the most requested, as a result of its price, moisture resistance and fire resistance. Mineral wool is more expensive, but delivers top protection against fire, water and sound. Usually constructed from recycled jeans, cotton insulation is an earth-friendly choice that provides great performance.

Blown-In Attic Insulation

A specialized machine is used to add blown-in attic insulation, which can include fiberglass, cellulose, mineral wool or cotton. Cellulose is a wise material if you have many tight areas to fill, like around pipes, wiring or framing. While cellulose is budget-friendly and fire resistant, you’ll also have to consider that it can take in moisture and flatten 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 filling cracks and other tricky-to-access areas. It’s extremely durable, doesn’t go down and provides a natural sound barrier.
