Hi all,
I have a first floor room in the house that forms a "bridge" over a car port, between my house and the neighbour's house. The floor appears to be a normal suspended floor, with t&g floorboards and the underside (ie the car port ceiling) being boarded with some kind of asbestos board.
There is no underfloor ventilation, and the direction of the joists means no cross ventilation will occur even if I did fit ventilator grilles at each end.
Am I correct that if I lift the boards and lay insulation ontop of the car port ceiling that condensation between the top of the insulation and underside of the floorboards is not going to be a problem? My reason for this assumption is that the underside of the floorboards and the top of the insulation will both be warm. My only concern is that the joists will act as cold bridges and there may be pontential for condensation to form on them?
