Proper Attic Insulation Levels

In Maryland and Virginia, attic insulation should have a total R-value (the standard performance rating for insulation) between 38 and 49. Traditional fiberglass batts have about 3.5 R-value per inch. If you merely have a few inches of batting in the attic, you’re probably paying too much for utilities and not getting optimal comfort.

Coverage is just as important as thickness. Look for open space around batts or pockets where loose-fill insulation has settled over the years. Replace the attic insulation or add new loose-fill, blown-in, or spray foam insulation to create a more complete barrier.

Comparing Attic Insulation Options:

Attic insulation comes in several materials and formats. Here’s what you should know about the most common options:

    • Loose-fill cellulose or fiberglass – Spread by hand to fill all the corners and gaps, loose-fill insulation sits on the attic floor. This increases your home’s energy efficiency because your HVAC barrier is at the ceiling, rather than the roof, so you aren’t paying to heat and cool the attic. Cellulose costs a little more but features a higher R-value.
    • Blown-in cellulose or fiberglass – We use a commercial-grade machine to fill the attic floor with blown-in attic insulation. This method uses small pellets, so fewer gaps remain. Blown-in insulation works incredibly well in attics with obstacles like mechanical equipment or irregular ceiling joist shapes.
    • Spray foam insulation – With a higher R-value and the ability to stick to ceilings, spray foam insulation offers superior performance and lets you continue using the attic for storage. If you do have HVAC equipment in the attic, or it’s a conditioned attic, you’ll definitely want spray foam to create a barrier at the roofline.
    • Batting insulation – Best suited to attics with regular joist shapes (so the batts fill the spaces or can be easily cut to fit), batts offer reasonable R-values for a good price. You can choose from fiberglass or recycled denim batts.
