This tool is designed to work for the Cardinal Louvered Roof product and uses the ASCE 7-16 wind code in IBC 2018 to determine wind pressures to use with their span tables.

The results will not be accurate or applicable if used for the more widely used ASCE 7-10 code or for other louvered roof systems. Check with your local municipality for the applicability of the wind standard.
