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.Get a free quote

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.
