Secondary Glazing by Crown Conservatories Hampshire

Secondary Glazing


Secondary glazing involves installing supplementary glazing on the inside of an existing single-glazed window.  This is a money-saving option for those who need extra insulation, but don’t perhaps have the budget available to completely replace single glazed units with double-glazing. 

One of the main reasons why you may choose to replace your existing windows or install secondary glazing is to increase the energy efficiency of your home, helping to reduce your energy bills. Double glazing windows achieve this more effectively, however there is still a saving to be made with secondary glazing.  It also may be an attractive option if you live in a listed building, as you can make your home more energy efficient without the need for planning permission.

Secondary glazing will also help to reduce noise pollution, and because there is a greater cavity between the two pieces of glass in a secondary glazed unit, it has a better dampening effect to cutting out noise than a double glazed unit.

Horizontal Sliding Secondary Glazed Windows

Our horizontal sliding secondary glazed windows blend unobtrusively with most types of existing windows.  Highly efficient in sealing qualities, these windows are combined with easy opening action.  Fitted with nylon skids or ball raced stainless steel rollers, horizontal and vertical slide units are all double-sealed with twin Polypropylene Weatherpile.  Hinged units are retained closed by a semi-automatic catch.

Secondary glazed frames are available in many styles, including circular, square, arched, vertical slider, horizontal slider, lift-out, lift-out over lift-out, hinged or shaped.

If you would like to view secondary window options, please pop in to one of our showrooms, located in Fleet and Arborfield.  No appointment is necessary, but if you would like a chat before you visit, please call 01252 617385 or take advantage of the Crown ‘Request a Call Back’ option.
