Insulation questions, answered by experts

Yes, the air in your home needs some release; otherwise, moisture can get trapped inside the layers of insulation and potentially lead to mold and mildew. An insulation contractor near you should be able to determine the precise amount of insulation that will seal your home, keep you comfortable, and not lead to any mold.

The most affordable way to insulate behind unfinished walls is to install fiberglass batts or rolls. These total around $0.75 per linear foot, with the width matching the gaps between standard studs perfectly. However, it’s important to consider the R-value of your insulation and the climate in your area, as fiberglass insulation isn’t the best in terms of preventing heat transfer. Plus, the most affordable option may cost more on electricity bills over time. The most affordable way to insulate behind finished walls is to leave them up and use blown-in insulation to avoid drywall replacement.

The cost of installing spray foam insulation is $2,760 on average, but this cost can be as low as $650 or as high as $7,700. The main cost factor is the size of the insulated area and the type of spray foam insulation. 

Polyurethane spray foam costs between $0.44 and $1.50 per board foot, where a board foot is equal to the volume of a one-foot length of a board. More expensive options, like soybean or vegetable oil spray foam, range from $1.50 to $3.00 per board foot.

On it own, aluminum siding has a relatively low insulation value (also called R-value); aluminum siding has an R-value of 0.61. However, you can purchase insulated aluminum siding to increase the R-value to between 2 and 5. You can also install additional insulation within your walls to help maintain temperatures within your home. On average, insulation costs $1,825 to install throughout the typical home.

Bathroom wall insulation not only keeps the area temperate, but it also reduces instances of mold, mildew, and rot. Bathrooms, after all, are havens for moisture. With this in mind, it’s absolutely worth it to insulate bathroom walls since it saves money in the long run. You won’t have to hire a pricey mold remediation service down the line. Also, insulation decreases outdoor noise and lowers energy costs.
