Insulating Basement


Postby sjh1977 » Tue Oct 11, 2011 9:56 pm

Hello,

Im about to start renovating my basement at a ski chalet in France. All walls/floor are concrete and perfectly dry. My question is, should I use rigid foam board and fasten them straight onto the concrete walls, tape all joints and seal all gaps. Or, do I need to have an air gap between the wall and the insulation? I have looked into this subject in great detail but I seem to get various ideas/opinions on condensation/moisture build up etc. After the insulation is in I will batten then clad the walls with ship lap style softwood timber..Any tips or advice much appreciated, thanks in advance :)

paint the entire area with a buitumin paint first,then fix your 50x50mm battens fit your insulation boards inbetween then nail your t&g cladding to the battens.
The buitumin paint will prevent moisture,but you will need to install an airbrick for ventilation or leave a window open to prevent condensation
