50MM PIR insulation board (1 and a bit sheets) (Muirhouse EH4)

Manufacturer is Recticel, but its equivalent to Celotex/Kingspan/etc.

1 full sheet (2.4m x 1.2m) 50mm PIR insulation board.
1 partial sheet of the same.
Various offcuts (useful for filling in small bits, but you don't have to take them if you don't want to :D)

I can cut it down to fit into transport if required.
