Keep It or Pitch It: Should I Take Out Old Attic Insulation?

Having the right insulation thickness in your attic doesn’t merely keep your home pleasant. It can help you save a lot of money on your heating and cooling costs.

If you are concerned your home is among the 90% in the United States that doesn’t have enough attic insulation, now is an excellent time to install more. Having enough insulation helps balance your house’s temperature and prevent wintertime issues such as ice dams, according to the Insulation Institute.

As you get ready to begin putting more insulation in your attic, you might be considering 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 damp or damaged, you can typically keep it. We recommend hiring a pro who specializes in attic insulation in Kansas City, like Neal Harris Service Experts. That way, you’ll know your attic insulation is added accurately and matches building code standards. Correct installation also means you’ll enjoy maximum benefits for energy efficiency.

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

How Much Attic Insulation You Should Put In

ENERGY STAR® suggests attics should have at the very least 14” of insulation, which provides an R-value of 38. Attic insulation R-value measures 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 influenced by the kind of insulation you install, its thickness and how it’s installed. When you work with a company like Neal Harris Service Experts, our specialists 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?

Neal Harris Service Experts chooses the ideal insulation for your attic by including where you reside, your budget and how much insulation you need to install. Here are the types of attic insulation we install.

Batt Attic Insulation

This type of insulation is available in sheets trimmed to fit your attic and is constructed from fiberglass, mineral wool or cotton. Fiberglass is the most often installed, due to its price, moisture resistance and fire resistance. Mineral wool is pricier, but delivers excellent protection against fire, water and sound. Usually constructed from recycled jeans, cotton insulation is a sustainable solution that provides outstanding performance.

Blown-In Attic Insulation

A distinct machine is used to install blown-in attic insulation, which can contain fiberglass, cellulose, mineral wool or cotton. Cellulose is a good choice if you have lots of tight 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 changes to a hard foam on contact. It offers the strongest barrier against air, vapor and water. Spray foam attic insulation is great for plugging cracks and other difficult-to-access locations. It’s extremely strong, doesn’t go down and offers a natural sound barrier.
