Keep It or Toss It: Should I Remove Outdated Attic Insulation? 

Having the proper amount of insulation in your attic doesn’t merely keep your residence energy efficient. It can help you save lots of money on your utility costs. 

If you suspect your house doesn’t have enough attic insulation, now is a good time to install more. Having adequate insulation helps regulate your home’s temperature and stop wintertime troubles like ice dams, according to the Insulation Institute

As you prepare to begin putting more insulation in your attic, you might be considering if you need to do attic insulation removal. Not necessarily, and here’s why. 

In Most Cases, You Can Keep Old Attic Insulation 

Unless your existing insulation is soggy or damaged, you can typically keep it. We suggest calling a professional who specializes in attic insulation in the U.S., like Service Experts Heating, Air Conditioning & Plumbing. That way, you’ll know your attic insulation is added properly and matches building code standards. Accurate installation also means you’ll reap max benefits for energy efficiency. 

If your insulation appears to be shiny pebbles or chips, stop before adding extra insulation. Vermiculite insulation was often installed in homes built earlier than 1990. The EPA says you should assume it has asbestos, which can result in cancer. Don’t touch it or disturb it and get in touch with a pro who specializes in asbestos removal. 

How Much Attic Insulation You Should Have 

ENERGY STAR® advises attics should have at least 14” of insulation, which offers an R-value of 38. Attic insulation R-value gauges how efficiently insulation can stop heat. If you reside in a northern climate, up to 18” or an R-value of 49 is advised. 

R-value is also impacted by the type of insulation you use, its thickness and how it’s added. When you work with a pro like Service Experts Heating, Air Conditioning & Plumbing, 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? 

Service Experts Heating, Air Conditioning & Plumbing determines the right insulation for your attic by including where you reside, your budget and how much insulation you need to install. Here are the types of attic insulation we install. 

Batt Attic Insulation 

This type of insulation is available in sheets trimmed to fit your attic and is built 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 pricier, but provides excellent protection against fire, water and sound. Typically made from recycled jeans, cotton insulation is a sustainable solution that delivers excellent performance. 

Blown-In Attic Insulation 

A specialized machine is used to put in blown-in attic insulation, which can be made from fiberglass, cellulose, mineral wool or cotton. Cellulose is a good material if you have many little spaces 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 decrease as the years pass. 

Spray Foam Attic Insulation 

This liquid insulation converts to a hard foam on contact. It provides the broadest barrier against air, vapor and water. Spray foam attic insulation is ideal for sealing cracks and other hard-to-access locations. It’s extremely durable, doesn’t settle and gives a natural sound wall.
