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 Islington

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) Islington

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 Islington

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 Islington

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 Islington

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.

It's not somewhere you go on and sit, but still, it's nicer to have some green than just a busy roundabout it used to be.

Attractive new public space that used to be a main road.




2 years ago

At the moment the space is mainly only being used on the outer edge where there is a low wall which is popular for people to sit on to have something to eat, chat and watch the bustling Highbury Corner area with it's busy station and plenty to do. Unfortunately there are some people who are using the grassed area as somewhere to throw their rubbish. It's a real shame as we have waited a very long time for all the works around the old roundabout to be finally completed so it would be sad for it to be spoilt by people littering. Though I did not understand the need to spend a fortune changing the traffic system to two ways instead of a roundabout, at least there is now a green space that can be enjoyed by all.

The permanent collection changes regularly, which by itself makes it worth visiting at least once a year. Exhibitions are usually small (a couple for large rooms), but well curated. Bonus: the food at the café is lovely, as is the seating area in the garden.

Friendly, well organised modest gallery on a few floors in Islington. Based on an Italian collection it has a strong Futurist feature. Staff are friendly and helpful and there is a pleasing shop. Handy for bus and tube.
