Where can I find specs for what would be adequate trusses? I have a room with a 24 ft. span and my contractor is using trusses where the bottom plate is composed of 2x4s butted together and fastened with a metal plate. Is this ok?
If you are questioning the integrity of the trusses that your contractor is using, you may want to ask for the copy of the sealed truss design drawings. The truss design drawing is a graphic depiction of an individual truss prepared by the truss designer that prescribes truss geometry, materials and load conditions. This contains the “proof” that the trusses will work.
