We have a chill in our house on the second floor, I think it's because of the old casement windows. I am now wondering what to do with them and how I can deal with this problem. Who has had experience with this, please advise me.

I understand your concerns. I too had casement windows, but I solved the problem by ordering secondary glazing sash windows from the professionals. We went to Sash Window Refurbish and they did an excellent job. Especially in winter, it made a big difference to the insulation of the house. I recommend contacting them!

Thanks for the tip, I will definitely look into this service. Your experience and recommendation is very valuable to me. Hopefully the secondary glazing will help make the house warmer and cozier in the winter.

We will be friends together on the same forum. Let's join hands on this same coin. Play bubble shooter with me now！
