Honestly, I had the same issue not long ago. While searching, I came across https://www.tintfit.com/shop/energy-saving-insulation and read through their info. It helped me understand how insulation films can reduce heat loss through windows. The explanation is simple and not overloaded with technical details. I haven’t tried it yet, but it gave me a clearer picture. Might be useful for you too. Also, it seems like a cheaper option compared to replacing windows. I liked that you don’t need to do anything complicated to try it. It feels like a practical starting point.
