‘Secondary glazing’ means inserting a second pane of glass in or on to an existing window frame. This approach can help reduce heat loss and noise. It’s an alternative to retrofitting new double-glazed windows, especially for old wooden houses. We have a comprehensive range of styles for every application, these include Lift Outs, Vertical Sliders, Hinged Units and Horizontal Sliders, Balanced Vertical Sliders and Tilt-in Balanced Vertical Sliders. Our Secondary Glazing System has excellent thermal insulation. Harmful effects of ultra violet radiation can also be reduced whilst letting in solar heat.
The Horizontal Slider is undoubtedly the most frequently used type of secondary glazing. Its uses are therefore widespread, being applied to high rise or low-level commercial properties, historic buildings as well as all kinds of domestic dwellings.
The Balanced Vertical Slider is the most complex type of secondary glazing system. It is applied generally to older properties. It is particularly suited to the refurbishment and upgrade of the nation’s architectural heritage. This is the most common form of secondary glazing used in sash windows.
Lift Out secondary glazing’s most common application is where limited access to the primary window is required, for example a window which has been installed with the sole object of providing light to a room.
The Hinged Unit provides the most appropriate solution, when it comes to providing an unobtrusive secondary glazing system, since there are no transoms or mullions to spoil the view. The reduction in noise, and improvement in thermal insulation, greatly enhances both the living and working environments, though this applies equally to all of our styles of secondary glazing.
Secondary glazing is another window fitted on the inside of you existing window, our system is aluminium with a hardwood sub-frame, it is some times called secondary windows.
In order to obtain a quotation we will need widths x heights x style (two panel vertical slider, three panel horizontal slider, hinged unit etc) You would be well advised to give us a call and we can advise the best course of action for your individual requirements
Yes, but we recommend that you draught proof the existing window as well
Yes, considerably, for extra sound proofing consider a different thickness of glass to the existing glass, different thicknesses cut out different wave lengths giving improved noise reduction. Also consider laminated glass for improved sound reduction, apart from ordinary laminated glass there is now a new generation of acoustic laminated glasses. For additional reduction of noise pollution leave a 4″ (104mm) cavity, line the reveals with acoustic tiles leaving a 3mm gap between the tiles and the prime window. Once again draught proofing the existing window is vitally important, you would be amazed that people/firms do not carry out this basic requirement
Yes, the cavity formed between the prime and secondary windows is an effective thermal insulator, if the cavity is more than 4″ (104mm) then you can get thermal currents within it that will decrease the insulation value.
The advantages are: Reduced noise pollution, Lower heating costs, Added Security, Increased Comfort
