Keep It or Toss It: Should I Take Out Outdated Attic Insulation?

Having the proper amount of insulation in your attic doesn’t just keep your residence cozy. It can help you save major money on your heating and cooling expenses.

If you are concerned your home is among the 90% in the United States that doesn’t have adequate attic insulation, now is a fantastic time to add more. Having adequate insulation helps regulate your home’s temperature and halt wintertime troubles such as ice dams, according to the Insulation Institute.

As you get ready to begin putting more insulation in your attic, you could 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 damp or damaged, you can usually keep it. We suggest partnering with a specialist who specializes in attic insulation in Boise, like TML Service Experts. That way, you’ll know your attic insulation is installed correctly and achieves building code standards. Proper installation also means you’ll enjoy maximum benefits for energy efficiency.

If your insulation resembles shiny pebbles or chips, stop prior to adding extra insulation. Vermiculite insulation was commonly installed in homes built prior to 1990. The EPA says you should assume it has asbestos, which can cause cancer. Don’t touch it or disturb it and contact a pro who specializes in asbestos removal.

How Much Attic Insulation You Should Put In

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

R-value is also affected by the type of insulation you have, its density and how it’s installed. When you work with a professional like TML Service Experts, our specialists 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?

TML Service Experts chooses 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 is available in sheets sized 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 more expensive, but offers excellent protection against fire, water and sound. Often made from recycled jeans, cotton insulation is a sustainable solution that delivers outstanding performance.

Blown-In Attic Insulation

A special machine is used to install blown-in attic insulation, which may be made from fiberglass, cellulose, mineral wool or cotton. Cellulose is a good option if you have a lot of tight spots to fill, such as around pipes, wiring or framing. While cellulose is budget-friendly and fire resistant, you’ll also have to consider that it can hold on to moisture and flatten over time.

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 ideal for filling cracks and other difficult-to-access locations. It’s extremely strong, doesn’t go down and provides a natural sound wall.
