Insulation questions, answered by experts

If the temperature outside is around 90 or 100 degrees with the sun beating on your home’s roof, it’s common for the attic temperature to reach 150 degrees or more. This excessive heat shows the importance of having a radiant barrier in place along with insulation. The radiant barrier reflects the heat entering the attic back upward, keeping your home’s temperature more consistent.

The lifespan of insulation depends on the material type. Fiberglass can last between 80 and 100 years, but it is important to start checking it around the 15-year mark. Spray foam has a lifespan of up to 100 years, and mineral wool can last up to 100 years. Cellulose, an eco-friendly option, has a lifespan of 20 to 30 years.

On average, insulating an attic costs about $2,500, with a typical range of $1,500 to $3,500. The final price often depends on the attic's size, with costs generally falling between $1 to $3 per square foot. For example, insulating a 1,800-square-foot attic would likely cost between $1,800 and $5,400.

If the project involves removing old insulation, this can add an average of $900 to the total cost, bringing a full removal and reinsulation project to around $3,000.

Several factors influence the overall cost:

  • Insulation Type: Prices per square foot vary significantly by material.

  • Reflective: $0.50–$1.50

  • Blown-in: $1–$4

  • Batt: $2–$4

  • Loose-fill: $2–$5

  • Spray foam: $2–$5

  • Structural insulated panels (SIPs): $4–$7

  • Project Complexity: Factors like sealing air leaks, poor attic accessibility, and required inspections can add to the cost.

  • Removal Issues: The discovery of mold, asbestos, or pests during the removal of old insulation can substantially increase the price.

All garage doors, particularly newly installed models, add value to your home. Higher-quality and higher-priced doors increase the ROI, so a well-insulated custom garage door increases the value of your home more than a poorly-insulated stock model. Updating a garage door boasts the second-highest home improvement ROI, at nearly 95%.

You can purchase bags of cellulose and loose-fill fiberglass blown-in insulation from the same local home improvement store where you rent your blower. If you want to use rock wool insulation, you may need to special order it.
