Hi,
I have a damp problem in the living room of our home which I am trying to prevent. The house is a traditional build with 18" stone walls, no insulation, no cavity and no blockwork internally. To prevent damp forming on the walls I have injected the wall with a damp course and it also has an electric wire damp course. Therefore we presume the damp is condensation. Internally the build up inside of the original plaster wall is a layer of polythene, 3" x 2" timber studs fixed directly to the wall, infilled with 2" Kingspan and 1" Kingspan fixed directly over the top of the studding. None of the above is sealed/taped although the material joints all occur on a timber stud. The final element of the wall build up is a 1/2" plasterboard. The problem I am having is interstitial condensation is forming behind the insulation on the polythene layer. Why am I still having a problem and what would be the best way to overcome it?! Thanks in advance!
