Secondary Glazing

Secondary Glazing solutions offered by Knowles Stained Glassworks

Knowles Stained Glassworks have installed many Secondary Glazing systems around London, Surrey and Sussex in both domestic and commercial properties and we understand that due to the current economic climate, many people can no longer afford to replace their existing windows. Secondary Glazing helps as it significantly improves acoustic installation, thermal efficiency and reduces condensation whilst still being cost efficient.


What is Secondary Glazing?


Secondary Glazing is a fully independent window system, which is installed to the room side of the existing window. The original window remains in position and in their primary unaltered form. Secondary Glazing allows variation and can be adaptable as it is available as open-able, removable or as a fixed unit. The open-able panels allow access to the external window for cleaning and ventilation purposes. The fixed form of Secondary Glazing is designed to be removed during the warmer months when thermal requirements are not necessary.
