We moved house last year and have a Victorian Cottage, which has windows in it that are more than 15 years old.
At this time of year especially, they get condensation on the inside, and feel drafty, Which I don’t mind in some rooms, but the lounge is especially cold as it’s North facing and gets no sunlight, so eager to find a solution until we can afford to replace them.
They are standard double Glazed UPVC by the way.
Thanks 🤞
