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 house hold bills. Our Secondary Glazing is made from strong light weight aluminium so that the frames can be made very slim. This makes the additional window more discreet and much less obtrusive. Making them perfect for use in listed buildings and conservation areas. Duration Windows have the broadest range of bespoke secondary glazing in Europe, with many products unique to Duration.
