FAQs

Secondary glazing is an additional pane of glass fitted to the inside of your existing window.

It creates an insulating gap between the original window and the secondary panel, helping to reduce noise, improve thermal efficiency and minimise condensation without replacing your existing windows.

It’s particularly popular in listed buildings, conservation areas and period properties where retaining the original windows is important.

If your existing frames are still in good condition, secondary glazing can deliver similar benefits to new windows at a fraction of the cost, without the mess and disruption of full replacement, and those that already have double glazed window frames, adding secondary glazing really does amplify the results.

Secondary glazing is specifically designed to upgrade your existing windows without replacing them.

Whether your current windows are single or double glazed, we can install a tailored secondary glazing system to improve thermal efficiency, reduce noise, and minimise condensation, this all sits within the reveal of your existing window or door frames.

There are three main reasons why misty glass and condensation happens. This could be because of window drainage issues; the install was carried out incorrectly or the seal has broken meaning that water and moisture can get between the two panes of glass. We will always carry out some drainage slots before installing the new double glazed sealed unit, if we discover any blockages.

The level of noise reduction depends on your existing windows and the secondary glazing system selected.

In many cases, professionally installed secondary glazing can reduce external noise by up to 80%, helping create a quieter and more comfortable living or working environment.

Secondary glazing helps to reduce condensation by improving the thermal performance of your windows and limiting the temperature difference between inside and outside.

This can greatly reduce the build-up of moisture on your existing glass. In homes with humidity problems, sometimes the condensation can be worse, at Misty Glaze we advise our customers to invest in a de-humidifier, this helps with this common problem within properties in the UK, as most condensation is caused by moisture within the property caused by lack of ventilation and cooking plus the drying of clothes.
