oliveau Posted December 14, 2009 Share Posted December 14, 2009 We live in a modernish [mid - seventies] house built with a half buried sous-sol. Construction is concrete block and render. I rather think it's hollow concrete block. However the outside walls let a lot of cold through in the winter, and heat in the summer.Does anyone know if there is an effective cavity wall insulation available in France?

Théière Posted December 14, 2009 Share Posted December 14, 2009 And the bad news....unless your walls are built from two rows of seperate blocks rather than the large ones with holes in the cavity wall insulation would be of no use as the cold will simply use the bridge area and you could suffer condensation.Either attach insulation to the outside or the inside of your walls.http://www.homebuilding.co.uk/feature/how-insulate-old-houses Link to comment Share on other sites More sharing options...
Patf Posted December 14, 2009 Share Posted December 14, 2009 Our first house here was built like that, and the inside walls were covered with lambris (which I hate) behind which was a thick layer of fibreglass insulation. It was quite a warm house. Link to comment Share on other sites More sharing options...
