Keep It or Toss It: Should I Get Rid of Aging Attic Insulation? 

Having the correct amount of insulation in your attic doesn’t just keep your residence comfy. It can help you save lots of money on your utility bills. 

If you suspect your house doesn’t have ample attic insulation, now is a great time to install more. Having adequate insulation helps even out your house’s temps and halt wintertime problems including ice dams, according to the Insulation Institute

As you prepare to begin putting more insulation in your attic, you might be thinking 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 existing insulation is damp or damaged, you can typically keep it. We recommend partnering with a pro 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 matches building code standards. Accurate installation also means you’ll get max benefits for energy efficiency. 

If your insulation resembles shiny pebbles or chips, stop in advance of adding extra insulation. Vermiculite insulation was often installed in homes built before 1990. The EPA says you should suspect it contains asbestos, which can lead to 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 Have 

ENERGY STAR® suggests attics should have at least 14” of insulation, which offers an R-value of 38. Attic insulation R-value measures how well insulation can divert heat. If you reside in a northern climate, up to 18” or an R-value of 49 is suggested. 

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

Service Experts Heating, Air Conditioning & Plumbing figures out the ideal insulation for your attic by taking into account where you live, your budget and how much insulation you need to add. Here are the types of attic insulation we put in. 

Batt Attic Insulation 

This style of insulation is available in sheets trimmed to fit your attic and is made from fiberglass, mineral wool or cotton. Fiberglass is the most popular, due to its price, moisture resistance and fire resistance. Mineral wool is costlier, but offers excellent protection against fire, water and sound. Often built from recycled jeans, cotton insulation is a green option that delivers excellent performance. 

Blown-In Attic Insulation 

A distinct 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 choice if you have many small areas 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 hold on to moisture and settle as time passes. 

Spray Foam Attic Insulation 

This liquid insulation changes to a hard foam on contact. It gives the strongest barrier against air, vapor and water. Spray foam attic insulation is great for plugging cracks and other difficult-to-get at spots. It’s extremely tough, doesn’t flatten and offers a natural sound block.
