Keep It or Toss It: Should I Remove Outdated Attic Insulation?

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

If you suspect your residence is among the 90% in the United States that doesn’t have ample attic insulation, now is a great time to add more. Having enough insulation helps regulate your residence’s temps and stop wintertime problems like ice dams, according to the Insulation Institute.

As you get ready to begin installing more installation in your attic, you might 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 current insulation is soggy or damaged, you can typically keep it. We recommend partnering with a pro who specializes in attic insulation in Roanoke, like Service Experts Heating & Air Conditioning. That way, you’ll know your attic insulation is put in like it should be and matches building code standards. Correct installation also means you’ll get top benefits for energy efficiency.

If your insulation resembles shiny pebbles or chips, stop in advance of adding additional insulation. Vermiculite insulation was often installed in homes built before 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 professional who specializes in asbestos removal.

How Much Attic Insulation You Should Add

ENERGY STAR® suggests attics should have at least 14” of insulation, which offers an R-value of 38. Attic insulation R-value determines how well insulation can divert heat. If you reside in a northern climate, as much as 18” or an R-value of 49 is recommended.

R-value is also influenced by the style of insulation you use, its depth and how it’s installed. When you work with a company like Service Experts Heating & Air Conditioning, our Experts take all the guessing 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 figures out the right insulation for your attic by including where you reside, your budget and how much insulation you need to add. Here are the types of attic insulation we use.

Batt Attic Insulation

This kind of insulation is installed in sheets sized to fit your attic and is constructed from fiberglass, mineral wool or cotton. Fiberglass is the most popular, because of its price, moisture resistance and fire resistance. Mineral wool is pricier, but offers top protection against fire, water and sound. Typically constructed from recycled jeans, cotton insulation is a green choice that delivers excellent performance.

Blown-In Attic Insulation

A specialized machine is used to put in blown-in attic insulation, which can contain fiberglass, cellulose, mineral wool or cotton. Cellulose is a smart option if you have lots of small spaces to fill, such as around pipes, wiring or framing. While cellulose is budget-friendly and fire resistant, you’ll also have to realize that it can hold on to moisture and decrease as time passes.

Spray Foam Attic Insulation

This liquid insulation changes to a hard foam on contact. It provides the best barrier against air, vapor and water. Spray foam attic insulation is fantastic for filling cracks and other hard-to-get at locations. It’s very heavy duty, doesn’t go down and offers a natural sound wall.
