Truss storage/design loads

Seeking a good narrative about storage areas in trusses…

Thanks in advance.



Attic trusses are typically designed with a square room opening in the web members and the bottom chord is usually larger. The typical common truss with triangular web openings is not designed for attic storage. These are typically designed to carry only the ceiling drywall and insulation (10psf)



Good question and great answer . We all can learn much from this forum. Thanks all… Roy
