I live in a 1920s semi. I am currently doing up the knock-through lounge/dining room, and it seemed like a decent time to think about putting in some underfloor insulation. (I am a southerner but live in the north, so am in need of some extra layers to protect my soft self from the harsh Arctic winds of Sheffield)...
My house is on a hill (where isn't, in Sheffield?) so the dining room has quite a large space underneath, while the lounge towards the front has less space. Was thinking of doing Kingspan board (or a cheaper equivalent) between the joists without any kind of membrane. Is this right?
However, when I moved into the house, the survey said that there was a bit of damp (minor, nothing serious) under the floor in the hallway. A company came in and said this was due to poor ventilation, so they put in a load of airbricks. I now have 6 (two on each side).
Will this be enough ventilation to insulate under the floor, or will I end up with a dripping, cold damp space and rot everywhere?
Advice v much appreciated!
