Easy DIY install of a secondary glazing unit. Great product, looks good, good price, excellent communication and advice.

The website is very easy to use, I ordered acoustic glass because of a noisy neighbour. Very satisfied with the build quality and the fit was perfect. More importantly, it works, very good at blocking noise.

Easy to order website, good communication and efficient delivery. The Slider fitted perfectly. Vicky was great with the follow-up making sure the whole process had gone smoothly.
Different openings need different solutions. Start your quote with the system that best matches the way your window needs to work.
Perfect for wide multi-pane windows that have vertical bars, such as casement windows. Panels slide to give easy access to the existing window for ventilation and can be removed for cleaning.
Ideal for windows with horizontal bars, such as vertical sliding sash windows. Available with balances and with a tilt back easy clean facility.
Ideal for bays, providing fire escape and specialist applications. Can provide a large clear opening for greater ventilation and full access to the existing window.
Suitable for windows with a large clear glass area, windows in hard to treat areas or tight spaces. Ideal for bay windows and where other secondary styles are not possible.
Inexpensive, ultra slim-line and very simple to fit. Our Fixed secondary glazing is a system in its own right and is suitable where access to the existing window is not required.
Secondary glazing is a smart way to improve comfort, reduce outside noise, and help retain the character of an existing window. It is especially useful for traditional homes, listed properties and buildings where full replacement is not desirable.
Suitable specifications can help reduce external noise and improve comfort.
Add another barrier between inside and outside to support thermal comfort.
Purpose-designed systems can remain discreet and sympathetic to the opening.
A range of styles, colours and glass types to suit the project.
