Continuing yesterday’s work I have inserted more horizontal supports to frame the structure especially at the top under the existing beam. This has allowed me to Putin the vertical sheet behind the exposed stone blocks. Not ray to work at height, trimming out the PU foam that has expanded well past the joints and stops the plywood going in cleanly. So progress was slow but eventually I got it in.

The window fitters return Monday to install the final windows and shutters and to commission all the motors.
