This might be bad advice depending on the insulation of the outer walls. If you increase the insulation on these windows, the water might still condensate, but this time on your walls where you cannot see it or wipe it away. A rule of thumb is to insulate the outer walls better than the windows.
And that's how we got mould this year ๐ Hopefully the owner will isolate the walls next year...
