Moved into a house a few months ago (have asked quite a few questions about it already!) and have had condensation issues which have been discussed elsewhere on this forum. Water vapour sources have been reduced as much as possible by the installation of extractor fan in the bathroom (door always closed), extractor in the kitchen and no washing dried in the house.
Humidity is mid 50%.
My question is whether or not I have cold bridging on my windows and door frames. Ever single one at ground level has a stip of beading condensation even if the glass and no other surface does. The issue is that all of the frames are wood and it has badly affected the wood over time. Photo below as example. The black line you see on both is where the water builds - not running down onto it, that is where it is formed. The windows and doors aren't leaking and there is no detectable draught at these points.
So as I can't realistically reduce the amount of water vapour we create and the house is heated to roughly 19 degrees all the time is there anything that can be done? I'm guessing it is a design/build flaw with these windows and doors as they all suffer the same thing and all were installed at the same time (about 12 years ago).
Short of removing them all or installing a PIV should I just sand and varnish them and accept it or can it be helped?
Cheers.

I didnt mean frames - I meant the sills. All the sills are wood but all the doors and windows are plastic.
