The barn doors were built around 2" thick 4' x 8' insulation board cores.

Insulation cores were sandwiched with bead board panels.

The panels were framed in, compressed with 3/4" pine rails and through-bolted with carriage bolts.

Finally, the panels were trimmed-in with beveled stock around the frame perimeters. Surface mounted strap hinges were then installed.
