As stated elsewhere on this forum, we've at last managed to buy a property with cavity walls, after decades of living in draughty, condensation-affected Victorian properties with solid brickwork.
We've just had our first genuinely cold evening since the Spring, and I was rather disappointed to find extensive condensation on the inside of the double glazing units. These units are UPVC, have probably been fitted within the last 20 years and are beaded on the outside, although security-wise a local fitter has reassured me that the units are secured with clips. Point is, why would I have ANY condensation with cavity walls? Is it because the inside walls are warmer, and therefore the only place for any water vapour to go is on the cold inside pane of the glazing units? In our last house we had little if any condensation on the windows, but a dreadful problem with condensation on the walls which I could only address by having a dehumidifier running for several hours a day.
