Keep It or Throw It: Should I Remove Aging Attic Insulation?

Having the right amount of insulation in your attic doesn’t merely keep your house comfy. It can help you save major money on your heating and cooling expenses.

If you suspect your home is among the 90% in the United States that doesn’t have adequate attic insulation, now is a great time to install more. Having ample insulation helps regulate your house’s temps and halt wintertime troubles including ice dams, according to the Insulation Institute.

As you prepare 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 Instances, You Can Keep Old Attic Insulation

Unless your current insulation is soggy or damaged, you can usually keep it. We advise calling a professional who specializes in attic insulation in Charlotte, like Komfort Air. That way, you’ll know your attic insulation is put in like it should be and achieves building code standards. Proper installation also means you’ll reap top benefits for energy efficiency.

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

How Much Attic Insulation You Should Put In

ENERGY STAR® suggests attics should have at least 14” of insulation, which provides an R-value of 38. Attic insulation R-value determines how efficiently insulation can stop heat. If you live in a northern climate, as much as 18” or an R-value of 49 is advised.

R-value is also impacted by the kind of insulation you have, its density and how it’s added. When you work with a company like Komfort Air, we’ll take all the guessing out of R-values and how much insulation needs to be put in.

What’s the Best Insulation for My Attic?

Komfort Air figures out the right insulation for your attic by including where you own your home, your budget and how much insulation you need to add. Here are the types of attic insulation we use.

Batt Attic Insulation

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

Blown-In Attic Insulation

A specialized machine is used to install blown-in attic insulation, which may contain fiberglass, cellulose, mineral wool or cotton. Cellulose is a smart option if you have many tight spots 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 flatten as time passes.

Spray Foam Attic Insulation

This liquid insulation transforms to a hard foam on contact. It delivers the broadest barrier against air, vapor and water. Spray foam attic insulation is great for sealing cracks and other hard-to-access spots. It’s highly tough, doesn’t settle and gives a natural sound wall.
