I have been investigating insulation options in my 1930's chalet house and have found that I can get pretty good access to the head of the external cavity wall at the top of the ground floor.
I can see right to the bottom and there is no insulation.
So this gives me a opportunity, do I fill with as thick a board of celotex I can, or do I use something else?
Any ventilation requirements in the cavity I need to consider?
