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

Having the right insulation depth in your attic doesn’t only keep your residence pleasant. It can help you save major money on your utility costs.

If you think your residence is among the 90% in the United States that doesn’t have ample attic insulation, now is an excellent time to add more. Having adequate insulation helps balance your home’s temps and prevent wintertime issues like ice dams, according to the Insulation Institute.

As you prepare to begin adding insulation to 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 often keep it. We advise partnering with a specialist who specializes in attic insulation in Austin, like Strand Brothers Service Experts. That way, you’ll know your attic insulation is added like it should be and achieves building code standards. Proper installation also means you’ll reap maximum benefits for energy efficiency.

If your insulation appears to be shiny pebbles or chips, stop before adding additional insulation. Vermiculite insulation was often installed in homes built before 1990. The EPA says you should suspect it has asbestos, which can cause cancer. Don’t touch it or disturb it and call a professional who specializes in asbestos removal.

How Much Attic Insulation You Should Put In

ENERGY STAR® suggests attics should have at minimum 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, up to 18” or an R-value of 49 is suggested.

R-value is also influenced by the kind of insulation you use, its density and how it’s added. When you work with a pro like Strand Brothers Service Experts, we’ll take all the guesswork out of R-values and how much insulation needs to be installed.

What’s the Best Insulation for My Attic?

Strand Brothers Service Experts chooses the ideal insulation for your attic by considering where you own your home, your budget and how much insulation you need to have. Here are the types of attic insulation we put in.

Batt Attic Insulation

This style of insulation is installed in sheets cut 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 delivers top protection against fire, water and sound. Typically built from recycled jeans, cotton insulation is an earth-friendly option that provides great performance.

Blown-In Attic Insulation

A distinct machine is used to install blown-in attic insulation, which could include fiberglass, cellulose, mineral wool or cotton. Cellulose is a wise choice if you have many small spots to fill, including around pipes, wiring or framing. While cellulose is budget-friendly and fire resistant, you’ll also have to consider that it can take in moisture and decrease as the years pass.

Spray Foam Attic Insulation

This liquid insulation transforms to a hard foam on contact. It offers the strongest barrier against air, vapor and water. Spray foam attic insulation is ideal for sealing cracks and other difficult-to-access locations. It’s extremely tough, doesn’t go down and gives a natural sound barrier.
