Secondary Glazing

Many home owners can only insulate their property with secondary glazing because they live in a listed building or a conservation area.

Adding secondary glazing systems is a simple and stylish solution involving adding an extra slim-line internal window within your window reveal or to your existing window frame. This means the external appearance of your property is not affected. Hazlemere supply and fit a range of bespoke secondary glazed windows, each custom built to your needs. Like double glazing, it is designed to insulate your home and reduce external noise. Secondary glazed windows are available single glazed or double glazed in any RAL colour and are lightweight, durable and require very little maintenance.

Secondary Glazing - for a warmer, quieter life.

Secondary glazing involves adding an extra slim-line window in addition to your existing windows. Secondary glazing is designed to keep the heat in and the noise out. You could also save around 10% on your household bills by fitting our secondary glazing. Duration Windows have the broadest range of bespoke Secondary Glazing in Europe and have been manufacturing since 1985. Secondary Glazing is particularly suitable for use in listed buildings & conservation areas.

Secondary glazing is perfect for both residential or social housing on main roads - even where double glazed windows are already fitted. Any building where altering or replacing the prime window is not possible or not cost effective, such as listed buildings and rented accommodation, will benefit from the installation of secondary glazing. Our aluminium secondary glazing is of the highest quality, light weight, highly effective, with a range of specialist glass for maximum noise reduction and thermal performance. Built to last, it is virtually maintenance free and will give you many years of trouble free service.
