sidewall heights are outside dimensions of the siding. The inside
wall height is four inches less. For example, the inside height of the
Elite Gable sidewall is 6'8".
to Taller Walls: To make a building 1' taller, multiply $3.05 times the perimeter of the building.
For example, to convert a 10x12 Gable Shed to 8' walls: add 10+12+10+12 = 44 feet, then multiply times
$3.05 = $134.
