Board foot. A board foot (BF) is the unit of measurement for hardwood lumber. A board foot is 1 foot long x 1 foot wide x 1 inch thick. (1 foot = 0.305 metres, 1 inch = 25.4mm) The formula for determining board feet in a board is: (Width in inches x length in feet x thickness in inches) divided by 12. The percentages of clear wood required for each grade are based on this 12' unit of measure.
How to Measure Foam Board Feet Calculation Tool Spray Foam requirements are calculated in Board Feet. Simply described a Board Foot is an area of cured foam measuring 12 x 12 square x 1 thickness after curing. Our Spray Foam Kits come in 3 board ft. sizes for small or large projects. How to Calculate Board Feet: Measure the square footage of the area to foam (Width x Height = Square Feet) Determine cured foam thickness in inches to achieve target R-value (apprx. R-7 inch) Multiply Square Footage of project times (X) the cured foam thickness desired. Example: 10 ft x 30' area = 300 S.F. x 2 foam thickness = 600 board ft. of foam
