Keep It or Pitch It: Should I Get Rid of Aging Attic Insulation?

Having the correct insulation depth in your attic doesn’t only keep your house energy efficient. It can help you save lots of money on your heating and cooling costs.

If you suspect your house is among the 90% in the United States that doesn’t have enough attic insulation, now is a great time to install more. Having enough insulation helps balance your house’s temperature and prevent wintertime problems including ice dams, according to the Insulation Institute.

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

In Most Homes, You Can Keep Old Attic Insulation

Unless your present insulation is soggy or damaged, you can often keep it. We recommend calling a pro who specializes in attic insulation in Charleston, like Pardee Service Experts. That way, you’ll know your attic insulation is put in like it should be and meets building code standards. Accurate installation also means you’ll get max benefits for energy efficiency.

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

How Much Attic Insulation You Should Have

ENERGY STAR® advises attics should have at minimum 14” of insulation, which offers an R-value of 38. Attic insulation R-value gauges how effectively insulation can block heat. If you have a home in a northern climate, as much as 18” or an R-value of 49 is suggested.

R-value is also impacted by the style of insulation you use, its thickness and how it’s put in. When you work with a company like Pardee Service Experts, 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?

Pardee Service Experts determines the best insulation for your attic by including where you reside, your budget and how much insulation you need to have. Here are the types of attic insulation we use.

Batt Attic Insulation

This style of insulation comes in sheets trimmed to fit your attic and is made from fiberglass, mineral wool or cotton. Fiberglass is the most popular, because of its price, moisture resistance and fire resistance. Mineral wool is costlier, but provides greater protection against fire, water and sound. Often constructed from recycled jeans, cotton insulation is a green solution that delivers excellent performance.

Blown-In Attic Insulation

A special machine is used to install blown-in attic insulation, which can contain fiberglass, cellulose, mineral wool or cotton. Cellulose is a wise option if you have many small areas to fill, such as around pipes, wiring or framing. While cellulose is competitively priced and fire resistant, you’ll also have to take into account that it can take in moisture and flatten as the years pass.

Spray Foam Attic Insulation

This liquid insulation converts to a hard foam on contact. It offers the strongest barrier against air, vapor and water. Spray foam attic insulation is ideal for filling cracks and other tricky-to-access spots. It’s very long-lasting, doesn’t flatten and offers a natural sound block.
