This is a common question asked by homeowners looking to have spray foam insulation installed in their home. General contractors and builders also wonder what is the cost to use spray foam insulation in their next project in place of traditional insulation. There are a lot of factors that effect the cost of spray foam insulation. If you are building a new home, renovating, or looking at adding additional insulation to your home, your spray foam insulation cost can vary based on what you choose.
There are two types of spray foam insulation commonly used today; Open Cell spray foam and Closed Cell spray foam. Open Cell spray foam typically costs around $0.40 to $0.70 per board foot depending on the amount of foam sprayed and the application circumstances. Closed Cell spray foam usually costs around $.75 to $1.50 per board foot with similar factors effecting the overall cost of the application. Also, in many states there are Energy Rebates for people who use spray foam insulation.
What type of spray foam insulation should I use?
Open Cell spray foam is a low density product typically with a density of around .5 lb per cubic foot. Half Pound (.5 lb) Open Cell spray foam insulation typically has an R-Value of around 3.5 -4.2 per inch. The material expands approximately 100 times it’s liquid volume during the application process, allowing it to adequately seal any gaps, cracks, or penetrations on or around the substrate. Open Cell spray foam insulation is typically used in exterior walls, ceilings and attic spaces. This product is also used as a sound barrier and can be sprayed between floors and inside of interior walls.
Closed Cell spray foam is medium density product typically with a density of around 2.0 lb per cubic foot. Two Pound (2 LB) Closed Cell spray foam insulation has a higher R-Value of around 6.1-7.2 per inch. It expands approximately 30 times its liquid volume during the application process, which also gives this product the ability to perform as an air barrier and air seal your attic and other areas of the home. It can be used in all areas that Open Cell is used as well as other areas such as crawlspaces and basement walls. Closed Cell spray foam insulation is resistant to moisture and therefore works well in damp environments. Closed Cell also adds a lot of structural integrity and rack strength to the structure.
How does spray foam insulation cost compare to the cost of traditional insulation?
The cost of adding spray foam insulation to your next project may be 3 to 4 times the cost of traditional insulation, but the results will surely pay for themselves over time. Most people who ask the question “How much does spray foam insulation cost?” should probably also ask themselves, “How much money does spray foam insulation save me?”. Typically houses that use spray foam see anywhere from 25% to 75% savings compared to houses that are not insulated well and do not have proper air sealing. Therefore, although the cost of spray foam insulation may be higher than other insulation methods, the long term savings make it worth to consider spray foam insulation.
