Secondary Glazing

Secondary glazing can provide the benefits of modern glazing solutions, including increased energy efficiency and draught prevention, while retaining existing external windows

Our secondary glazing systems that are made from Accoya™, our preferred wood, come with a 20 year joinery guarantee in addition to the 50 year guarantee against rot.

Bespoke Secondary Glazing for your Windows

Our timber secondary glazing solutions are unique depending on the configuration of the existing casement or sash windows that are to be retained and on the individual design choice. Some of the period designs we can replicate include: Georgian windowsEdwardian windows; and Victorian windows. All our secondary glazing is manufactured from our workshops in Berkshire and fitted by our expert installers.

Manufactured and Fitted

We have been manufacturing and installing secondary glazing into grade II listed buildings and period homes across London and the South for over 25 years.

Like our replacement timber windows, secondary glazing can be manufactured with a variety of different paint, ironmongery and glass options to suit your needs.

Secondary Glazing Benefits

There are numerous benefits of installing secondary glazing in your home. Not to be confused with double glazed windows, our secondary glazing service involves fitting an additional window behind the existing external sash or casement window. This can be of particular benefit if you own a listed building, are restricted by planning constraints, or would like to retain the integrity of your period building.

Having an additional window installed can increase the security of your home, providing an additional obstacle to stop unwanted intruders.

Like double glazing, installing secondary glazing can help improve thermal insulation, offering energy cost savings. It can also help reduce noise by creating an extra barrier for external noise coming into your home.
