I need to insulate the inside door for the cupboard where the CU is. It's an old window cavity in a 750mm thick stone wall and is fully ventilated from the under floor.
The door is just ply so it is just a case a cutting the Kingspan to fit and then 'gluing' on - Which glue please ? My thinking is one of the 'Sticks-Like-Shit' varieties.
Thanks Rob
