What is Retrofit Double Glazing?

​“Quite simply, it's the process of replacing your single-pane glass with insulated double-glazed units, expertly installed into your existing frames. It’s genuine double glazing designed to enhance your home’s comfort, energy efficiency, and noise reduction—without the need for entirely new window frames.”
