For any style of window
Permanently fitted and accessible

A fixed secondary glazed window is an independent window that is permanently fitted on the inside of an existing door or window. It’s ideal for when space is limited, or when minimal access to the primary window is required. For this reason, our fixed units are incredibly popular in large-scale commercial projects.

Turn button releases are optional to enable removal for cleaning and maintenance if required. Available in several different styles as well as single or double-glazed aluminium profiles, there are a number of configurations to choose from.

Secondary Glazing Illustration
The Granada difference
Quiet
Secondary glazing offers the most effective sound insulation. Reduces noise by up to 80% and significantly outperforms double glazing.
Warm
Improves thermal insulation of existing single-glazed windows by around 65%, approximately 10% more than double glazing achieves.
Secure
An affordable, discreet, highly effective solution to enhancing security. No external access required, ideal for multi-storey buildings.

The Spec

Sporting the same slim and unobtrusive aluminium profile, these units are suitable for shaped applications like arches. Glazing options are from 4mm – 28mm glass with a choice of predrilled or face-fixed. It is also the most economical option to secondary glaze existing windows.

Economical yet high performance

Despite its low price, fixed secondary glazing still offers all the advantages synonymous with secondary glazing, namely 80% noise reduction, 65% extra thermal insulation and enhanced security. Once the insert panel is attached to the existing pane, it can be fixed permanently into position on a window or door then it is trimmed and sealed all around the edges.

Bespoke shapes and guarantee

Most of our secondary glazing styles are in two different product ranges -the Traditional which is the entry level system, and the Heritage which the flagship product. Note the product is unsuitable for fire escape locations as this would not comply with building regulations.
