Keep It or Toss It: Should I Take Out Outdated Attic Insulation?

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

If you suspect your residence is among the 80% in Canada that doesn’t have enough attic insulation, now is a fantastic time to add more. Having adequate insulation helps balance your home’s temps and prevent wintertime issues 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 Instances, You Can Keep Old Attic Insulation

Unless your present insulation is damp or damaged, you can usually keep it. We suggest working with a pro who specializes in attic insulation in Kingston, like Service Experts Heating & Air Conditioning. That way, you’ll know your attic insulation is installed like it should be and matches building code standards. Proper installation also means you’ll have max benefits for energy efficiency.

If your insulation looks like shiny pebbles or chips, stop before adding more insulation. Vermiculite insulation was commonly installed in homes built before 1990. The EPA says you should presume it has asbestos, which can cause cancer. Don’t touch it or disturb it and contact a professional who specializes in asbestos removal.

How Much Attic Insulation You Should Add

ENERGY STAR® suggests attics should have at least 14” of insulation, which gives an R-value of 38. Attic insulation R-value gauges how well insulation can block heat. If you have a home in a northern climate, as deep as 18” or an R-value of 49 is recommended.

R-value is also influenced by the style of insulation you have, its thickness and how it’s added. When you work with a professional like Service Experts Heating & Air Conditioning, our specialists take all the guessing out of R-values and how much insulation needs to be added.

What’s the Best Insulation for My Attic?

Service Experts Heating & Air Conditioning chooses the best insulation for your attic by including where you reside, your budget and how much insulation you need to add. Here are the types of attic insulation we use.

Batt Attic Insulation

This type of insulation comes in sheets cut to fit your attic and is constructed 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 more expensive, but provides excellent protection against fire, water and sound. Typically made from recycled jeans, cotton insulation is a sustainable solution that gives excellent performance.

Blown-In Attic Insulation

A specialized machine is used to put in blown-in attic insulation, which may be made from fiberglass, cellulose, mineral wool or cotton. Cellulose is a good material if you have lots of small areas to fill, like around pipes, wiring or framing. While cellulose is economical and fire resistant, you’ll also have to realize that it can take in moisture and settle as time passes.

Spray Foam Attic Insulation

This liquid insulation transforms to a hard foam on contact. It gives the broadest barrier against air, vapor and water. Spray foam attic insulation is fantastic for sealing cracks and other difficult-to-get at locations. It’s extremely tough, doesn’t flatten and provides a natural sound barrier.
