Not sure where best to put this, but I am thinking of re-decorating our front room. As part of this work I'd like to insulate the floor by taking up the floorboards, fitting pieces of kingspan between the joists, supported on screws screwed into the joists so that they stick out a little bit to support the bits of kingspan, then either put back the original floorboards or lay a chipboard floor or lay new floorboards.
However this room has an open fire and I have been told that air needs to be able to enter the room from the gaps in the floorboards for the fire to work correctly, is that true. If I was to replace the fireplace with a living flame gas fire would the same problem still exist? Would putting slot vents in the window frame help?
