About Secondary Glazing
Secondary glazing involves adding an extra slim-line window in addition to your existing windows. Our secondary is made from slim-line, durable aluminium and we have been supplying this trusted and proven product since 1985. It is virtually maintenance free and will give many years of trouble free service. Secondary glazing comes in many styles and colours to match your existing windows to blend in with your property. Curtains and blinds remain unaffected most of the time. Perfect for listed buildings and rented accommodation where altering or replacing the prime window is not possible.
Our Secondary Glazing comes in either White, Silver or Brown finish and has 4mm Float Glass as standard.

What Does It Look Like?
Usually they are white, although optionally we can paint them any one of 200 colours. They are made from durable aluminium so they will not rot and require very little maintenance. As aluminium is a strong material the frames can be made slim so that it is less obtrusive. They come with covering trims so you don't see any of your fixing screws and the units are often pre-drilled for easier installation. Also, our secondary glazing can be curved to form arched secondary glazing windows.
