Greater clear span allows total flexibility in home design that conventional framing cannot achieve. Open-web construction allows routing of plumbing, electrical, and HVAC components without having to build for downs. Installation is fast and precise. 3-1/2'' wide gluing and nailing surface virtually eliminates squeaks in the floor system. A = span. B = rise. C = rafter length. Already having the rise will make it easy to determine the rafter length by loading the numbers into the equation chart. For example, a roof with a span of 20 ft and a rise of 7 feet needs rafters that are the square root of 400 + 49 = 21.2 feet. This does not include the extra length required for the ...As per LVL span rule of thumb, the depth of the LVL beam should be 1/20th of span in inches and their width is 1/3 to 1/4 of the depth.
