Secondary Glazing FAQ’s

Does Secondary Glazing actually work?

Secondary glazing is an excellent, cost effective way of reducing the amount of external noise entering your home through your current windows. This simple and cost-effective treatment can increase sound insulation. This means your home will be quieter and you will sleep more peacefully. In other words, yes, it does work! Secondary glazing is also extremely effective for thermal retention and draught exclusion.

Does Secondary Glazing add value to my house?

Secondary glazing can greatly increase your home's value. If your home is older and not performing well, it may be worth considering investing in new glazing options. This will increase its appeal to potential buyers as well as allow it to sell at a higher price. Selling a property that is quiet and warm adds to the appeal.

If my Secondary Glazing breaks, who can fix it?

The Glazier who installed your secondary glazing should have a well-documented warranty on their work. Meaning they should be able to fix it for you. We here at City Sound proud ourselves on our craftmanship as well as the quality of our products, if any problems arise, please do not hesitate to contact us.

Secondary Glazing for Listed Buildings Chelsea

A building listed under the law is protected and Listed Building Permission may need to be obtained before any modifications can be made. Not all repairs will require consent. Please get in touch with your local authority and make enquiries as to whether you need permission to install secondary glazing.

Sash Windows (Vertical sliding) Chelsea

Sash windows, also known as “Vertical sliding windows”, are the most popular window type. Secondary glazing sash windows are also very popular.

Our sash windows consist of two panels, one at the top and one at the bottom. They are counter balanced with pre-tensioned springs that hold the panels’ weight. The window can be opened in any direction and the panels can be operated easily.

Horizontal Sliding Windows Chelsea

Horizontal sliding windows, which can be made side to side, are the most versatile style. They can be manufactured with either 2, 3, or 4 sliding panels. This type of secondary glazing matches perfectly with Crittal windows. Individual sliding panels can slide effortlessly, providing unimpeded access to external windows.

All of our windows sections are made from aluminium and powder-coated white. You can customize frames to match your decor with a different colour or finish.

Fixed Lift Out Chelsea

Fixed lift out windows are an alternative to screw-fixed units. They have a removable glass panel that can be lifted from the master frame and accessed through the external windows.

This type of window is used for external windows that are rarely used, or in offices with air conditioning where cleaning between windows is necessary.

Casement (Hinged) Secondary Glazing Chelsea

Our hinged (casement) windows can be side- or top-hung. This design allows easy access to outer windows or doors.

This type of window is popular in hospitals, surgery rooms, and laboratories because it has minimal dust ledges, tight seals, and is easy to clean.

We had a great time exploring this historic house. It’s exactly like stepping back in time. The staff were also kind enough to let us wander at our own pace, as I find it’s a problem at other historic sites.

I was transported back in time. If you are interested in history, and like me are drawn to old houses this is a gem. Not to be missed. A lot of information around the house. The guides were super friendly. Amazing this house and all it’s furniture has survived to today.
