After
The finished ceiling featuring 3/8 by 3 1/8 poplar beadboard. NOTE: There are no splices in the ceiling. We special ordered 20 foot poplar trim boards to case the ridge beam. There are no miters in the trim to detract from the ceiling.
Before
This photo shows ridge beam in ceiling. We installed 1/2 inch CDX plywood over drywall so we could install the beadboard vertically.
