A studwall was erected this week to cover the damp proof membrane that has been installed on the end gable. This will ensure that the plasterboard can be easily fixed to the stud (rather than trying to attach it to the waterproof membrane).
Fortunately, we seem to have over ordered the 50mm insulation boards so it is a simple case of cutting the boards to fit tightly into the panels in the stud wall.
It only took 1/2 day to complete this. I seem to have got the hang of this! You can see the time lapse here.
50mm insulation board has been cut tightly and jammed in place. It took half a day to insulate this end wall.
