Keep It or Pitch It: Should I Remove Old Attic Insulation?

Having the right insulation depth in your attic doesn’t merely keep your home energy efficient. It can help you save lots of money on your heating and cooling bills.

If you suspect your home is among the 90% in the United States that doesn’t have adequate attic insulation, now is a fantastic time to install more. Having enough insulation helps balance your home’s temperature and halt wintertime issues including ice dams, according to the Insulation Institute.

As you prep to begin putting more insulation in your attic, you might 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 often keep it. We suggest working with a specialist who specializes in attic insulation in Naples, like Service Experts Heating & Air Conditioning. That way, you’ll know your attic insulation is added accurately and achieves building code standards. Accurate installation also means you’ll have maximum benefits for energy efficiency.

If your insulation resembles shiny pebbles or chips, stop prior to adding more insulation. Vermiculite insulation was frequently installed in homes built before 1990. The EPA says you should presume it contains asbestos, which can lead to 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 Have

ENERGY STAR® advises attics should have at minimum 14” of insulation, which offers an R-value of 38. Attic insulation R-value determines how effectively insulation can divert heat. If you live in a northern climate, as deep as 18” or an R-value of 49 is recommended.

R-value is also impacted by the type of insulation you use, its depth and how it’s installed. When you work with a pro like Service Experts Heating & Air Conditioning, we’ll 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 ideal insulation for your attic by including 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 comes in sheets sized to fit your attic and is constructed from fiberglass, mineral wool or cotton. Fiberglass is the most often installed, because of its price, moisture resistance and fire resistance. Mineral wool is more expensive, but offers greater protection against fire, water and sound. Often made from recycled jeans, cotton insulation is a green option that delivers excellent performance.

Blown-In Attic Insulation

A special machine is used to install blown-in attic insulation, which can be made from fiberglass, cellulose, mineral wool or cotton. Cellulose is a wise choice if you have many tight areas to fill, such as around pipes, wiring or framing. While cellulose is economical and fire resistant, you’ll also have to take into account that it can hold on to moisture and settle as the years pass.

Spray Foam Attic Insulation

This liquid insulation converts to a hard foam on contact. It gives the broadest barrier against air, vapor and water. Spray foam attic insulation is great for plugging cracks and other hard-to-access locations. It’s extremely long-lasting, doesn’t go down and gives a natural sound barrier.
