Hi
I'm about to start on a selfbuild. Would like to use a suspended timber floor, in order to reduce the thermal mass of the house.
I would be grateful if anyone has any advice on how to insulate the floor inorder to minimise thermal bridging. I will be insulating between the joists, but am worried about heat transfer through them.
Also, how would you make such a floor airtight, should I lay the airtight membrane underneath the floorcovering and on top of the joists? or is it enough to tape the joints of the ply-floor covering?
Thanks in advance
All help appreciated!
