Hello everyone tonight:

I just thought that I would add a little to this thread

I once examined a very early school in the Maxville area we opened up one of the walls to observe how it had been constructed--the timber frame had been raised and the exterior had been covered with vertical boarding and batts. Then on the inside the cavity had been filled with clay bricks and bedded with a clay mortar, to the front face of the timberframe.

The window and door frames were placed in the walls ahead of the placement of the clay infil. Horizontal wood strips were placed in the rows of clay brick infil at about 24" intervals to attach the interior wall covering which in this case was very wide handplaned 1" beaded pine boarding, which was painted a lovely red colour

Above this interior horizontal boarding the clay filled wall had been plastered with a LIME plaster it must have been a beautiful wall in its day
