Attic Insulation FAQ

Roll of insulation

A lot of people are surprised to find out just how much of an improvement updated attic insulation can make in terms of their comfort and energy savings. However, before making that initial investment, homeowners have a lot of important questions regarding various insulation solutions for their homes.

Below, we gathered some of the most frequently asked questions we receive on this topic.

What are the benefits of updated attic insulation?

The attic is the most important location of a house to be insulated because most heat is lost through a home's attic. A properly insulated attic can decrease energy bills.

What are my insulation options?

Loose fill and batting are options for attic insulation. Loose fill is packed into bags and blown into place with specialized machines, which you can rent. Batting comes in packages rolls, typically 16 or 24 inches wide, and fits between the joists in your attic. On one side of batting is a foil or paper backing to act as a vapor barrier. You can install multiple layers of batting.

Which insulation should I choose?

Loose fill is ideal for attics in which the joists are irregularly spaced as well as those with many obstructions that you'll need to work around. If there is limited room to work in your attic, loose fill might be the best insulation choice. However, you'll need to be comfortable working with the equipment if you want the job done right.

While batting can be more difficult to use if there are many barriers, it can be cut to shape and doesn't require you to use special machinery.

What is insulation made of?

Loose insulation as well as batting can be made of fiberglass, cellulose, or mineral wool. You'll need a thicker layer of fiberglass than other materials, and it can irritate the lungs and skin. Fiberglass batting doesn't block air as well as other materials. Mineral wool is the most expensive but is fire resistant. Cellulose is cheaper but can become moldy when moisture is present, and batting is produced by fewer companies. Batting is also available in cotton at a higher price.

Do I need to remove existing insulation?

You may want to remove insulation that is damaged or has mold. However, you do not need to remove insulation that's in good condition.

What is R-value?

R-value is a measurement of the material's resistance to heat flow based on how thick the insulation is and what it is made from. Greater values mean better heat flow resistance. Common R-value recommendations for attics include R-30, R-38, and R-49, applying to warmer, temperature, and colder climates, respectively. You can check the ENERGY STAR recommendations for your area. You'll need to buy enough insulation to reach your target R-value.

Could my home have asbestos insulation?

Homes built before 1990 may contain asbestos insulation, which requires professional removal. This insulation looks grainy and loose with shiny flecks.
