Day 57 - Ceiling laths and roof insulation

Week 13 - Day 57
The work to put the ceiling laths in place continues.
Also today, an experiment in placing the roof insulation in place. This has to be put in place between the ceiling and the roof slates, but can't rest on top of the laths as the insulation will be laid before the plaster in spread through the laths to key it in place. So, the insulation needs to be laid over a mesh of string with clearance between it and the top of the laths!
With the laths in place some detail of the purlins becomes clearer to see from the top - but is hidden from view from below!
