Installing attic subfloor. Truss bottom chords are 24" oc but some are not too accurate. My 4x8 subflooring is missing some of the "joists" by 1/2" or so. What is an acceptable way to fix this? Can I sister 2x6s to the bottom chords of the trusses?
Before going to far with this are you even sure the trusses are rated for top loading?
Is this going to now be a conditioned area? (HVAC)
By adding plywood your cutting way down on the avalible space for insulation.
To ansewer your question, yes you can sister some 2 X 6's.
Thanks. These are attic trusses rated for 40 psf LL. the attic space will be conditioned. Do i need to sister the 2x6 the entire length of the truss (from wall to wall) or can i add it just where i need it in the center section of the truss?
