Hello, I am interested in the question about secondary glazing of double glazed classic windows. What are the benefits and where can I find professionals to do such a job?

Secondary glazing sash windows is great if you want to keep a classic style while providing good insulation. I did this in my home by contacting this company Sash Window Refurbish. They provide quality secondary glazing services for casement windows. Now my house is warm and comfortable even in winter.

Thanks for the advice, that sounds like exactly what I need. I will definitely look into secondary glazing and contact this company. Your experience and recommendation is very valuable to me.
