Spray foam insulation is one of the easiest forms of insulation to install. This is, however, a job for professionals as it requires expert skill and equipment. It is critical to know theulation spray foam ins cost before embarking on a given project. Since it is a highly advantageous insulation type, it is also more expensive than traditional insulation materials like fiberglass. Various factors determine spray foam insulation cost.
Closed-cell or open-cell foam insulation
There are two different forms of foam insulation, namely, closed-cell and open-cell foam insulation. Closed-cell foam insulation is massively dense because of its cell structure. This makes it impermeable to air and moisture. This makes it the material of choice for outdoor applications as well as areas that are prone to get exposure to the elements.
Open-cell foam is less dense than close-cell foam. It is used in interior applications as it is not impermeable to vapor. It is, however, impervious to air and functions well at the sound reduction. This is the primary factor that will impact your installation cost. Closed-cell foam has massive advantages as it has double the thermal resistance, commonly referred to as R-value, as an open-cell foam.
This makes closed-cell foam twice as better at thermal and sound insulation as open-cell foam insulation. This, however, makes it more than twice as expensive in installation than open-cell installation. The cost will be determined by the type of foam insulation you go with.
Other factors that determine cost
Foam cost is determined by the amount of space you will require having the foam installed in as well as the thickness you will need. This is measured by a unit known as the board-foot. The board-foot is a measure of 12 inches by 12 inches by 1 inch. You will need a professional to come and measure the space you require the foam installation in for you to get the correct quote.
The installation site is another factor that will influence the cost of installation. Crawl spaces in the basement and hard to reach areas will increase the cost of installation in comparison to open spaces like the attic. The complexity of installation is another factor to consider. Some installation sites require more preparation before foam application like covering floors and sheathing interior walls. If you can do some of that pre-installation work, you can be able to save on labor cost.
Spray foam insulation cost will also vary with the location you are in as well as the size of your project. You can be sure to reduce your overall cost if you can do some of the work like pre-application and post-application. Talk to your contractor to see if pitching in will reduce your cost.
