Much of the UK's housing stock includes sash windows and timber casement windows which by their very nature are prone to draughts, heat loss and excessive traffic and aircraft noise. To overcome these issues we recommend installing a secondary window behind your sash windows or casement windows. As well as enjoying greatly reduced energy costs you will make the room draught-free allowing you to use the whole room in comfort. If noise is a particular problem then fitting a secondary window with specialist acoustic glass will make sleepless nights a thing of the past.

Generally noise will enter your building through the windows and doors. This is evidenced by the difference in noise that you experience when the windows are open and when they are shut. Our Black Knight range of secondary double glazing windows gives good noise reduction and our upgraded Black Knight Heritage range using specialist acoustic glass will give you the highest level of noise insulation possible. For each particular application it is important to pay attention to the material that the primary window is made from together with the type and thickness of the existing glazing, the cavity distance that can be achieved between the existing primary windows and the new secondary windows and the type of glass that needs to be used in the secondary glazing.

We cover the major cities of London, Birmingham, Bristol, Manchester, Leeds and Liverpool together with many other areas.

Your staff arrived on time, completed the job quickly & efficiently, tidying up afterwards so you would not know they had even been there. The black ones look so much better against the black beams & the whole room has been vastly improved. Adam & Joe did a fantastic job, particularly bearing in mind fitting the units inside irregular beams can't have been easy. I would like to say that we are extremly happy about the final result, excellent work! We will definitely order again in the future for the remaining windows, probably around January or February next year.
