martin55 Posted November 5, 2023 Share Posted November 5, 2023 Hi, 4 of my double glazed windows in my bungalow suffer from severe condensation in the winters. The windows in question are north/south facing. Can anyone make suggestions to reduce. Ideally from an expert or someone who has a good understanding of physics, thermal, etc. Thanks.

RobLe Posted November 5, 2023 Share Posted November 5, 2023 I shall assume that the condensation is on the inside, in which case I suggest that you get a decent temperature and humidity meter, and ideally CO2 (not CO) as well - £50 will get this. What’s the window frame construction, photo? Most likely (jumping the gun on your answers) is that the RH is high and window is old school U=2.7 so two pronged attack would fix: replace glass and drop RH. If RH high but CO2 low (unlikely) then dehumidify; usually CO2 is also high, so you really should ventilate more - MVHR is the gold standard soln for this, other solutions are available🙂.

JohnMo Posted November 5, 2023 Share Posted November 5, 2023 Let's just go back to basics How are you heating and ventilating the property. The rooms in question what temp do you keep them at? Link to comment Share on other sites More sharing options...
