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 Pentonville

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) Pentonville

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 Pentonville

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 Pentonville

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 Pentonville

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.

I had a nice time at the London Canal Museum, it was very interesting, and I had a nice intro to the Ice Trade (who knew!) given by Tony, thank you. I would definitely recommend this museum for anyone interested in the Industrial Revolution and how transport was 2-300 years ago. its amazing to think how quickly it has developed really. Thank you and keep up the good work!

This is my sort of museum, as I am not an expert at art, so this the kind of museum I visit. I've been here a while ago, but still want to give my feedback on this place, such an interesting museum where I could learn a bit of history of London canal. The place is not huge, but one can learn a great deal of history of British canals. I really had a good time.

Such an interesting building - part of the rich history that the museum itself describes, with really informative exhibits. Loved seeing the canal tractor and the ribbon and lace plates collected by barge people.

Had a great time at clueQuest last week. As a group of four we took on Plan52, which provided plenty for each of us to do with some nice ‘discovery’ moments. There were a few set pieces which weren’t operating correctly, so we had to ignore a section until it was the right time to explore. But forgiving that, it was still a lot of fun and I would definitely go back to try the other games they have on offer.

Easily the best escape room I have ever done. We went with my family and it was the perfect birthday present for my dad. Not only are the puzzles so unique and fun, the staff there are absolutely fantastic. I cannot wait to go back and complete all the other rooms!

Brilliant place with several different escape rooms. Staff were friendly and our group with 5 young boys aged 10/11 had a brilliant time. Room was challenging for them but with some help they managed to complete it and felt very excited and proud of themselves. Recommended

Hired this lovely outdoor space for our children’s birthday party. Toilet, kitchen and tea hut. I can imagine it would be very tranquil without the kids! Be careful with smaller kids as there’s a pond that’s easy to fall in if they running about!

Lovely community garden, well looked after by all who take care of it. Such beautiful things to see and such friendly people. If you are going in the summer holidays then they won't be able to access the garden until 3pm which we weren't made aware of until we got there but other than that, lovely experience!
