Looking at a loft conversion in a 50/60s bungalow - the joists which would make up the floor are only 4" thick. Is this sufficient (doesn't feel right) and can we jsut screw a 2" piece onto each to strengthen?
Then at least we would have space to put insulation - we are thinking of replacing the 75mm fibreglass with 50mm celotex; are we right in thinking it would have the same thermal property?
