Keep It or Throw It: Should I Take Out Aging Attic Insulation? 

Having the proper insulation depth in your attic doesn’t only keep your house comfy. It can help you save lots of money on your energy bills. 

If you suspect your house doesn’t have ample attic insulation, now is a great time to add more. Having enough insulation helps regulate your home’s temps and halt wintertime problems such as ice dams, according to the Insulation Institute

As you get ready to begin adding insulation to your attic, you may 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 usually keep it. We recommend partnering with 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 put in like it should be and meets building code standards. Proper installation also means you’ll reap maximum benefits for energy efficiency. 

If your insulation looks like shiny pebbles or chips, stop prior to adding more insulation. Vermiculite insulation was often installed in homes built before 1990. The EPA says you should suspect it contains 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 Add 

ENERGY STAR® advises attics should have at least 14” of insulation, which gives an R-value of 38. Attic insulation R-value measures how effectively insulation can stop heat. If you have a home in a northern climate, as much as 18” or an R-value of 49 is suggested. 

R-value is also affected 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 & Plumbing, 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? 

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

Batt Attic Insulation 

This type of insulation is available in sheets cut 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 pricier, but delivers greater protection against fire, water and sound. Often built from recycled jeans, cotton insulation is a sustainable solution that delivers outstanding performance. 

Blown-In Attic Insulation 

A special machine is used to put in blown-in attic insulation, which could be made from fiberglass, cellulose, mineral wool or cotton. Cellulose is a good option if you have many little spaces to fill, including around pipes, wiring or framing. While cellulose is competitively priced and fire resistant, you’ll also have to take into account that it can retain moisture and settle over time. 

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 fantastic for plugging cracks and other tricky-to-get at areas. It’s highly tough, doesn’t flatten and provides a natural sound block.
