To calculate how much foam you require to complete a job, multiply the square feet of area by the thickness of the foam to be sprayed. If the area is 1000 ft2 and you want to spray the foam 2½” thick, then multiply 1000 ft2 x 2½” which equals 2500 bf of foam required to spray the area.

What is 200 board feet in square feet?

Spray foam kits are measured in board feet, or square feet. A 600 board foot kit will cover 600 square feet at 1 inch thickness or 300 square feet at 2 inches thick; a 200 board foot kit will cover 200 square feet at 1 inch thickness, and so on.

How do you measure board feet for insulation?

Subtract the square feet of doors and windows in that wall. Subtract 6% for the studs (which you won't be spraying) Take that total and multiply by 3.5″ for a 2″x 4″ wall, or 5.5″ if it is a 2″x 6″ wall. The result is the number of board feet you need to install to complete your project.
