Cold Bridging

cantwbr1

I am getting a lot of condensation on the frames of some of my windows and patio doors. I think that it is due to cold bridging on the frames as I'm not getting much condensation on the glass. Is there any way that I can check this and what are my options to fix the problem.
Thanks

What material are the windows. What rooms is this happening in. And what is the orientation of the windows/ room, i.e. is it facing north, south????

North and south facing. Kitchen (patio doors) and bedrooms

replace frames and achieve insulation continuity in new detailing

or open the windows for more ventilation..

Are the frames Aluminium- metal condensates easier than glass.

The condensation resistance factor (CRF) of a window is based on 2 factors (mainly). The glass and the frame- hence my mention of frame material as that is what is condensating in the OP's case. This problem could simply be the result of the frames but to be sure we need more information- i.e. age of windows, double glazing/ single glazing, frame material, etc. I have seen aluminium frames where a green scum forms due to the amount of condensation involved. In these cases the metal forms condensation before the glass. The reasons why that happens are to do with the CRF which varies for different parts of a window. There are ways of calculating both the CRF of the glass and the frame individually.

The windows are uPVC and 15 years old
