Benefits of Secondary Glazing
-
Noise reduction.
By providing an additional layer of sound insulation between your home and the outside world, this will help to see a reduction in noise pollution – whether it be troublesome neighbours, street noise or early morning wildlife.
-
Low maintenance.
Secondary glazing is a much less disruptive solution than replacing your windows, and our slim frames need little upkeep, requiring only minimal lubrication and the occasional clean.
-
Security.
Secondary glazing provides an additional protective barrier against intruders. Helping to keep your home safe all year round.
-
Cost savings.
With a faster installation process and fewer materials involved, opting for secondary glazing is considerably more affordable than replacing all the windows in your house completely with double glazing.
-
Keeps heat in.
Secondary glazing is an excellent way to increase the heat retention of your home, by reducing incoming draughts and preventing warm air from escaping through your existing window.
Most Popular Secondary Glazing Products
Horizontal Sliding Secondary Glazing
Designed to match your existing windows, horizontal frames slide smoothly open and closed on aluminium runners, helping keep heat in, and draughts out.
Hinged Secondary Glazing
This option is ideal for traditional casement windows, as the secondary glazing swings open on a small hinge, in line with the mechanism of the window behind it.
Vertical Sliding Secondary Glazing
Perfect for box sash windows, the panels in these vertical sliding frames move easily up, down and can tilt inwards to provide easy cleaning access to the original window.

Secondary Glazing FAQs
What's the difference between double glazing and secondary glazing?
Secondary glazing is a pane of glass fitted in a separate frame on the inside of your existing windows. Double glazing is two panes of glass with the space in between filled with argon gas and vacuum-sealed inside your actual window frame.
Do you need planning permission for secondary glazing?
It’s not usually necessary to obtain planning permission for secondary glazing, even on listed buildings, as it’s invisible from the exterior of the building, and doesn’t change the primary material of the building either. If for any reason you do require planning permission, Anglian will carry out the application process for you.
Does secondary glazing add value?
Secondary glazing can add value to your home, especially if you live in a listed or period home. It can keep you warmer by reducing draughts and preserving the appearance and condition of your existing windows.
Does secondary glazing reduce condensation?
Having Anglian secondary glazing installed in your property can help reduce the condensation that gathers in your existing windows.
How do you clean between secondary glazing?
Whether you choose Anglian horizontal, vertical or hinged secondary glazing, every design is either easily tilted or removed completely to enable easy cleaning, as well as access to the original window behind it.
How long does secondary glazing last?
When properly cared for, secondary glazing can remain effective for several decades. Anglian secondary glazing is covered by our 10-year guarantee, so if you do encounter any problems with yours, you can be sure we'll be on hand to help.
