Insulating Your Home’s Attic

As a significant source of energy loss in homes, the attic should be properly insulated. Even if yours isn’t finished, it needs to be insulated. In fact, failing to ensure you have the right amount of insulation in your attic can negatively affect your home’s overall energy efficiency.

Your material choice depends on your attic and unique situation, as there’s no one material that’s right for every attic or loft. Fiberglass batt insulation is one of the most commonly installed types and works well in many attics.

Blown-in fiberglass is ideal for filling in small gaps and cracks and has excellent soundproofing abilities. Spray foam provides total coverage and helps air-seal any space. Cellulose is environmentally friendly and is one of the best materials for soundproofing.

Benefits of Attic Insulation

Insulating or re-insulating your attic, including knee walls, offers several benefits. It can help:

  • Reduce energy bills
  • Make your home a more comfortable space
  • Create a uniform temperature throughout your house
  • Create a healthier environment in your home

Some of the frequently asked questions we receive about attic insulation in southern Wisconsin and northern Illinois are:

How much insulation do I need in my attic?

Heating and cooling account for about 42% of your utility bills.

Without adequate insulation, your HVAC system works overtime to keep your home comfortable, and your monthly bills will be higher. Upgrading your insulation can help bring down those energy costs.

The benefits of insulation are measured in R-values. High R-values offer better insulation protection. Attics should have R-values between 49 and 60.

What type of insulation is best for my attic?

The U.S. is divided into zones, and each zone has different recommended insulation levels. We’re in Zone 6, so our attic insulation should have R-values between 49 and 60.

Some attics in our area need more than one type of insulation. Most attics have fiberglass batts, which are very effective. But small gaps and cracks need a better fill-in, so blown-in fiberglass works well.

Spray foam insulation air-seals any area, including attics. The most environmentally friendly attic insulation is cellulose, which is also perfect for garages because of its soundproofing properties.

When should I replace attic insulation?

Obviously, if your insulation has water damage or mold, it needs to be replaced. Damaged insulation can compromise your and your family’s health.

Damaged insulation leads to bad indoor air quality, which is especially dangerous for infants and older people.

Signs you need to replace your attic insulation include:

  • Frozen pipes
  • Higher heating/cooling bills
  • Ice dams on roof/gutters during a cold snap
  • Pests seeking air movement (as insulation blocks air leaks)
  • Temperature fluctuations in rooms
  • Water/moisture in the attic

Homeowner tax credits are another incentive to add insulation to your attic, crawl space or garage.
