Obviously, there are variable factors that can influence the final cost per square foot of a spray foam insulation installation. Here are three things to remember when it comes to estimating the cost of spray foam insulation:
- Type: What type of spray foam insulation is being used? Does the project require closed cell insulation or open cell spray foam insulation to be used? While open-cell spray foam insulation is more cost effective than closed-cell, it is equally as effective in residential and commercial projects in providing thermal comfort, air sealing and moisture management.
- Quantity: How much material is required to complete the job? Open cell spray can cover more surface area than closed cell spray foam insulation. Why? It’s due to the soft, sponge-like texture that expands up to nearly 100 times its initial volume, while closed cell can expand between 40 and 60 times its initial size when applied. What does this mean? More material is required to cover the space. The required thickness of the material, dictated by building code or area of the home, also contributes to how much material is needed.
- Labor: Remember to factor in the price of a professional contractor’s labor costs. Unlike random home improvement jobs, like painting, spray foam insulation is not a DIY project and requires a certified professional to apply the material properly.
Don’t forget to factor in the location and climate. For example, southern climates are different than northern climates, and the price of spray foam insulation will also be impacted by the location of the building. Keep in mind, for instance, that closed cell spray foam is often used in areas prone to flooding, while open cell is a great choice for southern climates thanks to its ability to “breathe.”
Finally, consider that regional building codes may guide what product is required and how much.
