How to calculate the styrofoam needed?
Multiply the area in square feet by the result of thickness (inches) divided by 12:
Styrofoam [ft³] = area [ft²] * (thickness [in] / 12)
Or multiply the area in square meters by the result of thickness (centimeters) divided by 100:
Styrofoam [m³] = area [m²] * (thickness [cm] / 100)
Example: Calculate the styrofoam needed for a 100 sqft area for 12 in insulation thickness.
Styrofoam needed [ft³] = area [ft²] * (thickness [in] / 12)
Styrofoam needed [ft³] = 100 * (12 / 12)
Styrofoam needed [ft³] = 100 ft³
