The home remodel project encountered an existing composite header along the
north edge of the main cabin over an opening of approximately 11wide in an interior
wall (attached covered area adjacent to the wall in question). The existing header is
comprised of 2-2xI2 sawn lumber with a timber beam below the header. The timber is
planned to bc removed and the existing header size was verified to be inadequate for
current design loads with removal ofthe timber.
The header should be upgraded to (2) 13/4"x 11 7/8" LVLs with (2) 2x4 jack studs
each end. Lumber shall be Hem Fir 42 or better and LVL material shall be 2,0E or better,
If there are any questions, please do not hesitate to call me at 970-586-9388.
