You may not know but insulation is measured in "board feet". What is a board foot, you may ask? What happened to square feet? Not to worry! Here, we show why board feet are used when talking about spray foam insulation. A board foot is a volume measurement and has a total volume of 144 inches cubed or total measurements of 12 inches by 12 inches by 1 inch (generic form).
Board feet are used to refer to how much spray foam insulation will cover the area you want at the depth you require. A local Icynene contractor will be able to calculate the board footage of the space you want to insulate. Board feet can be confusing to some because it is a volume measurement, but because the cavity needs to be filled at a certain depth, volume is the only mathematical expression that works to calculate the amount you need. Without proper calculations, wasted material in your project can significantly cost you money, and therefore knowing what a board foot is and how to measure it becomes useful.
Talk to a licensed Icynene spray foam insulation contractor in your area to find out how many board feet are required for your project.
