Plank Frame Window

Plank Frame windows date from the early 18thc to early 19thc. Their thick side jambs were mortise and tenoned to the head jamb and a heavy sill. The jamb stock was generally beaded, because it was seen from the exterior of the house, and the sash rode up and down in a rabbet to the interior of the house. The window that we reproduced was built when window construction was transitioning to lighter frames, that had exterior casing, so we built a “transition” window frame. At 8′ x 4′, the window required the heavy jambs and joinery of plank frame construction, but it is adorned with a wide exterior casing the represents the styles of the times.
