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

Having the right insulation depth in your attic doesn’t only keep your home cozy. It can help you save major money on your energy bills.

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

As you get ready to begin adding insulation to 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 current insulation is wet or damaged, you can often keep it. We suggest working with a pro who specializes in attic insulation in Hilton Head Island, like Epperson Service Experts. That way, you’ll know your attic insulation is installed like it should be and meets building code standards. Accurate installation also means you’ll reap top benefits for energy efficiency.

If your insulation resembles 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 includes asbestos, which can cause cancer. Don’t touch it or disturb it and get in touch with a company 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 gives an R-value of 38. Attic insulation R-value measures how effectively insulation can divert heat. If you live in a northern climate, up to 18” or an R-value of 49 is recommended.

R-value is also impacted by the type of insulation you have, its density and how it’s added. When you work with a professional like Epperson Service Experts, our Experts take all the speculation out of R-values and how much insulation needs to be put in.

What’s the Best Insulation for My Attic?

Epperson Service Experts chooses the best insulation for your attic by considering where you own your home, your budget and how much insulation you need to install. Here are the types of attic insulation we put in.

Batt Attic Insulation

This kind of insulation is installed in sheets sized 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 more expensive, but delivers excellent protection against fire, water and sound. Usually made from recycled jeans, cotton insulation is an earth-friendly option that delivers excellent performance.

Blown-In Attic Insulation

A special machine is used to put in blown-in attic insulation, which may include fiberglass, cellulose, mineral wool or cotton. Cellulose is a wise option if you have a lot of small areas to fill, like around pipes, wiring or framing. While cellulose is economical and fire resistant, you’ll also have to take into account that it can take in moisture and settle 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 fantastic for filling cracks and other tricky-to-access areas. It’s very tough, doesn’t go down and offers a natural sound block.
