Customer has contracted there own foundation crew and we are to build off of there finished block basement. The block crew is going to put in the headers above two 9x8 garage door openings. These are on the hip side of the roof with one floor above. My question is instead of nailing the two 16" LVL'S together they are making a box header with insulation in between LVL'S. The LVL'S are approximatly 5" apart. Do you think this will be ok being only one of the LVL'S will be under the rim board for the floor and also be supporting the wall/hip roof frameing above?
