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 Clerkenwell

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) Clerkenwell

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 Clerkenwell

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 Clerkenwell

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 Clerkenwell

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.

This is a true hidden gem. Everything one reads in novels and sees in films comes to life among the moving and dignified curation. The war, the children's evacuation, the blitz, the suffragettes, calling the midwives ... so much reality and so many dreams. Highly recommended. Free entry too!

Just a short walk from the museum, this Rail Train ride is a must (it is included in the ticket price, so foolish not to give it a go). The carriages are quite small so breath in and don't look if you are claustrophobic. If you can get in and open your eyes, you're in for a treat. Cleverly designed around the original track this 15 minute tour includes stops at 2 platforms for very informative video walls of the systems history. Highly recommended.

I have just done the Mail Rail Tunnel Walk at The Postal Museum. I had a great time exploring this fascinating piece of London Post Office history. The guide was very knowledgeable and perfectly answered all questions. I was able to take tons of unique photos during the hour plus tour. I highly recommend this if you are up to a leisurely stroll for about a mile whilst taking in the most unusual views underneath central London! Not really for children, they would be better served doing the same tour but actually riding on the train itself through the tunnels.

Great fun for adults and kids alike. Whether you are interested in trains or history, its well worth the 2 hours. The Mail Rail tunnel tour lasts around 10-15 minutes and is done really well, with audio commentary and videos played on the old platforms to take you through the history of the tunnels. Make sure you head across the road to the Postal Museum too. They have some great interactive exhibitions for kids and some fantastic memorabilia.

It's a great park. I have a 2 year old that loves it.. I must say the playground is mostly for bigger kids but it has a couple of spots for little children as well. The other area is good for picnics and the young ones running around

LMA is Covid-secure with lots of ventilation and space. Whilst it is only operating an appointment system to view documents at the current time you can also now book an appointment via email to use the Information Area. This includes use of the reference library, computers, microfilm reader, browsing the paper catalogues and use of the facsimile maps. There are no copying facilities but you can pay for a one day camera pass to take your own photographs. Close by to the lovely Exmouth Market there are lots of great places to have lunch!

Visited for the interesting Past London exhibition. There were lots of informative images and displays. Didn't avail the services of the archive itself but many people were.

The archives are an excellent resource for finding out about the history of London so it's a pity that it feels so difficult to get to. It's poorly signposted and approaching from Bowling Green Lane, there was one sign that pointed in the wrong direction and no further signs. The entrance to the archive isn't obvious, either. To use the archive, you need to register and go there personally to get your pass (their History Card) before you can order resources, which effectively prevents new users from requesting research materials online. When I went to get my History Card, I had to wait 20 minutes to be seen in spite of there being 2 registrars available - one seemed to be doing nothing. Getting resources takes a minimum of 25 minutes from the order being placed. Free lockers. Clean toilets. Space to eat sandwiches. There's free access to worldwide Ancestry. There was an interesting exhibition about Londoners when i was there, on till 5th July 2017.

Definitely one of the coolest/most unique museums in London. The highlight of the experience would have to be the Mail Rail, there's also a pretty sweet activity room called sorted, which is good fun for little kids, they get to scan letters and parcels, and act like their in a sorting office. Can't really fault the place, but yeah if the activity room had a bit more in it, would be great, and if the Mail Rail was a little longer, then the whole experience would off been even more amazing. I'd highly recommend the whole experience for anyone, it's a good little family day out, equally it's also a good little museum date.

Absolutely loved it! There's a very informative mail rail to ride and experience, followed by an interactive museum. We then went around the galleries and loved learning and trying things out. A fantastic day out for people of all ages and especially great for families with children 😘 10/10 recommend

Not to be confused with the Mail Rail ride, that is in another building across the road, this is the museum, stuffed with memorabilia from the beginning to the present day of the Postal service. Brilliantly laid out and clearly informative, there are many interactive things for the little cherubs to play with. Even as an adult, I was enthralled. The café and gift shop add a small respite from the absorption of all that information. Nice to sit outside too on a dry day whilst waiting for the train time slot to approach. Yes the ticket for this part of the museum is valid for a full 12 months. So plan it for 2 birthday treats!!!!!!
