A picture REALLY does speak a thousand words.
The same window, before and after our customer DIY secondary glazed it.
Here’s what he had to say:
“I fitted the units on Sunday and was very pleased with the immediate results. The units are simple and well made, and (in my case) easy to fit. The condensation has stopped. The room is warm and quieter. The central section benefits from the glass being easy to clean, both inside and out, as the glass sections can be lifted out. The central vertical edging does not look out of place, as the window has central dividers anyway. I have attached a photo to show how it looks now, and a photo during the December cold spell”.
Thanks for your help
A happy customer
