Keep It or Pitch It: Should I Remove Outdated Attic Insulation?

Having the proper insulation thickness in your attic doesn’t only keep your home comfy. It can help you save a lot of money on your utility expenses.

If you suspect your house is among the 90% in the United States that doesn’t have adequate attic insulation, now is an excellent time to add more. Having enough insulation helps regulate your house’s temperature and stop wintertime troubles including ice dams, according to the Insulation Institute.

As you prepare to begin installing more installation in 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 existing insulation is wet or damaged, you can typically keep it. We advise partnering with a pro who specializes in attic insulation in Concord, like Freschi Service Experts. That way, you’ll know your attic insulation is added accurately and meets building code standards. Correct installation also means you’ll reap maximum benefits for energy efficiency.

If your insulation resembles shiny pebbles or chips, stop prior to adding more insulation. Vermiculite insulation was frequently installed in homes built earlier than 1990. The EPA says you should assume it has asbestos, which can cause cancer. Don’t touch it or disturb it and contact 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 gives an R-value of 38. Attic insulation R-value gauges how well insulation can stop heat. If you reside in a northern climate, as deep as 18” or an R-value of 49 is recommended.

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 pro like Freschi Service Experts, our Experts take all the speculation out of R-values and how much insulation needs to be installed.

What’s the Best Insulation for My Attic?

Freschi Service Experts determines the right insulation for your attic by taking into account where you reside, 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 comes in sheets sized to fit your attic and is built from fiberglass, mineral wool or cotton. Fiberglass is the most requested, due to its price, moisture resistance and fire resistance. Mineral wool is pricier, but offers top protection against fire, water and sound. Often made from recycled jeans, cotton insulation is an earth-friendly option that gives excellent performance.

Blown-In Attic Insulation

A distinct machine is used to put in blown-in attic insulation, which may contain fiberglass, cellulose, mineral wool or cotton. Cellulose is a smart material if you have lots of small spots to fill, including around pipes, wiring or framing. While cellulose is economical and fire resistant, you’ll also have to consider that it can take in moisture and settle as the years pass.

Spray Foam Attic Insulation

This liquid insulation transforms to a hard foam on contact. It provides the best barrier against air, vapor and water. Spray foam attic insulation is great for filling cracks and other tricky-to-access areas. It’s extremely durable, doesn’t go down and provides a natural sound block.
