Attic Insulation Cost Savings

Written on October 1, 2025   By thecradletheatre   in Home

Insulating your attic is a great way to reduce air leakage and help lower your energy bills, especially in the winter. The good news is that the cost of attic insulation can be recouped very quickly in home value and energy savings.* For example, Remodeler Magazine’s 2016 Cost vs Value report ranked attic insulation as the top project in terms of return on investment (along with kitchen and bath remodeling).

How Attic Insulation Delivers Cost Savings

Several factors can influence the cost of installing attic insulation, including your region’s climate and what type of insulation you choose to use. For instance, fiberglass batt insulation is the most affordable option, with costs ranging from $2 to $5 per square foot. This material is available in pre-sized panels that fit between attic joists and are held together with paper or metallic facing. While it is affordable, it may leave gaps in your attic if not fitted properly.

Other, more expensive options include loose-fill and blown-in insulation. These materials, which include cellulose and fiberglass, are blown into the attic using a special machine. They are more effective than traditional fiberglass and can fill nooks and crannies better than batt insulation. However, they can cost up to $1,500 for a 1,000-square-foot attic.

Finally, spray foam insulation offers the most comprehensive coverage and best sealant, but it is also more expensive than other options. It can only be installed by professional contractors who are trained to handle it safely and efficiently.
