A neighbour has removed his chimney breast and hearth in the living room. The joists go parallel to the the hearth and he has found himself with no central support to the joists. His solution was to run 50 x 100m joists right across, which is a span of about 3.30m.
The centres are 400 but the table I looked at says the max span for joists of that size is 1.84m. Is this going to give him problems? He hasn't yet covered them with flooring.
