How Much Attic Insulation Costs

A well-insulated attic can greatly improve the comfort and energy efficiency of a home, but it isn’t cheap. The overall attic insulation cost depends on the type of insulation, the attic’s square footage, and labor. Labor costs are the largest component of attic insulation installation and can vary from community to community.

The spray foam insulation selected has a big impact on cost as not all types of insulation are created equal. For instance, reflective insulation (which reflects radiant heat rather than absorbing it) is less expensive than comprehensive insulation but doesn’t work well in cool climates. Fiberglass batts and blown-in cellulose or rock wool insulation are more affordable than spray foam.

The recommended R-value for an attic is another factor that impacts the total attic insulation cost. A higher R-value requires more material, which in turn drives up the cost.

Other important factors that affect attic insulation costs include air sealing, the condition of the attic, and any existing insulation removal or replacement required. Air sealing is an essential step in insulating an attic, but can be quite costly if done improperly.

The final attic insulation cost also depends on whether a contractor is used for the installation. Labor rates for a general contractor can be higher than those of a local insulation company.
