How Much Does it Cost to Insulate a 1000 sq feet Attic

If you are planning to insulate your attic, then the cost of the entire attic insulation project is incredibly important to consider. Without the correct estimate, you run the risk of a half-finished project or buying insufficient insulation.

Blown-in insulation is the most common option in Canada, with many homes going for either fiberglass or cellulose. Blown-in insulation is preferred for being faster and more effective if adding insulation to an already existing home. For an effective insulation project, you want to go for a thermal resistance of between R-38 and R-49, which may cost you about $1.59 per square foot, which translates to about $1590 if your attic has an area of 1000 square feet. These costs do not include air sealing, ventilation, and vapor barriers, which will cost an additional $350-$1500.

Blown-in cellulose installation cost

Cellulose is a more eco-friendly option, considering that it is made up of recycled newspapers and non-toxic borates to make it fire, mold, and insect-repellant. Each bag will have a coverage of 12 square feet if you want an R-value of R-49. The pre-installation process can, therefore, be $0.83 per square foot if you opt for cellulose, which translates to $830 for attic insulation only. With an R-value of 3.6-3.8 per square inch and its lack of toxicity for both you and your pets, it is a solid choice.

Blown-in natural wool

Natural wool insulation is another alternative that you can go for if you require a sustainable, biodegradable, and natural solution with remarkable sound absorption and low risks of allergy. A 25-pound bag will, however, set you back $140, with a coverage of 38 square feet for an R-value of 30.

The costs of insulating your attic may sound hefty and overwhelming. Still, by incurring this initial cost, you will be able to reduce your energy bills and increase your home’s living value many times over. If you decide to sell your home, any potential homeowner will be impressed and willing to fork out a good sum for your home.
