I'm looking into laying floorboards in my lower ground floor flat where room height is a bit of an issue. At the moment it's a concrete floor. I was thinking of adding 12mm of celotex followed by 18mm tongue and groove chipboard and then 18mm wooden floorboards on top of that. My question is whether it's worth adding the 12mm of celotex. Will it make any difference to taking the chill off the floor? And will it prevent heat loss through the floor?
I've just ordered 3 radiators so don't want to go the underfloor heating route.
Thanks
