Keep It or Pitch It: Should I Take Out Old Attic Insulation?
Having the right insulation thickness in your attic doesn’t merely keep your home comfy. It can help you save a lot of money on your utility expenses.
If you suspect your home doesn’t have enough attic insulation, now is a great time to add more. Having enough insulation helps even out your home’s temps and halt wintertime troubles like ice dams, according to the Insulation Institute.
As you get ready to begin putting more insulation in your attic, you could 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 usually keep it. We suggest hiring 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 accurately and achieves building code standards. Accurate installation also means you’ll enjoy top benefits for energy efficiency.
If your insulation appears to be shiny pebbles or chips, stop before adding more insulation. Vermiculite insulation was frequently installed in homes built before 1990. The EPA says you should suspect it includes asbestos, which can result in cancer. Don’t touch it or disturb it and call a pro who specializes in asbestos removal.
How Much Attic Insulation You Should Put In
ENERGY STAR® suggests attics should have at the very least 14” of insulation, which gives an R-value of 38. Attic insulation R-value gauges how effectively insulation can divert heat. If you reside in a northern climate, as much as 18” or an R-value of 49 is suggested.
R-value is also impacted by the kind of insulation you use, its thickness and how it’s installed. When you work with a professional like Service Experts Heating, Air Conditioning & Plumbing, our Experts take all the guessing 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 figures out the ideal insulation for your attic by considering 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 style of insulation is installed in sheets trimmed to fit your attic and is made from fiberglass, mineral wool or cotton. Fiberglass is the most often installed, due to its price, moisture resistance and fire resistance. Mineral wool is costlier, but provides greater protection against fire, water and sound. Usually made from recycled jeans, cotton insulation is an earth-friendly choice that provides superb performance.
Blown-In Attic Insulation
A distinct machine is used to add blown-in attic insulation, which could contain fiberglass, cellulose, mineral wool or cotton. Cellulose is a smart material if you have many small spots to fill, such as around pipes, wiring or framing. While cellulose is competitively priced and fire resistant, you’ll also have to realize that it can take in moisture and flatten 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 sealing cracks and other hard-to-access locations. It’s extremely heavy duty, doesn’t settle and provides a natural sound wall.
