Secondary Glazing for Listed Buildings Chinatown
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) Chinatown
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 Chinatown
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 Chinatown
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 Chinatown
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.

Trafalgar Square is a public square in central London. The site is a significant landmark. The Square's name commemorates the Battle of Trafalgar. The Nelson's Column, Lion Sculptures and Fountains are the most popular attractions at the square. The square is a place for community gatherings and political demonstrations. It’s a place of relaxed atmosphere in the late afternoon.

Ah, the iconic landmark; the pigeons and statues; the somewhat notorious fifth plinth. This is a place which truly illustrates the heart of London and England. With the modern street performers meeting the historic monuments, it's a sign of the times and a glimpse into a microcosm of modernity.

Beautiful square. It was pretty busy when we went due to construction and several protests, but we were able to still see the fountains and get a small bit of appreciation of it all. It’s quite a lovely part of the city, so you could spend a while here people watching.

Some of the store and restaurant employees/employers in London Chinatown need a lesson in friendliness and kindness. They need to learn some manners. Such rudeness and not just from one person!

Very well maintained. A marvellous collection. Grand and majestic works of art. Excellently organized according to time periods, nations and art movements. There are benches and sofas for you to sit and rest awhile in every hall and room. I went on a Saturday and it was packed with people. I guess weekdays will be a better time to visit.

One of London's most famous museums and one you cannot (and should not) miss, the National Gallery is beautiful inside and out and will serve you with a perfect dose of art and culture during your trip. Its artworks span centuries so there will be something here for everyone, no matter your taste. I recommend paying a visit to this iconic museum at least once.

Fantastic visit. It is so much quieter so you are able to absorb far more. The guides are fantastic too and have time to explain far more and interact more. Alan was brilliant. Do go and enjoy this beautiful space and the national treasures. Its a good 3 hour visit with a fantastic cafe too.

A great experience visiting the M&M shop in London. So much on offer. Walls of M&M's! It is a bit pricey! Keep an eye on the weights you add to the bag... it soon adds to a small fortune! Had it not been so expensive it would have been 5 stars! The kids enjoyed it and that why we went

Brilliant I love it here. You can smell the chocolate as you walk in. Also have a few items on sale so you can grab a bargain. Kids love it here. Just a word of warning.. don't let your kids fill the sweet bags themselves. I put a few of different sweets in a bag and it still came to £5. I saw kids with bags full must be well over £30.

Absolutely fantastic place to visit with the family. There's so much to see. There's chocolates of various flavours and colours. You can have your own face printed on M&M's. There's accessories and t-shirts and clothing and cushion and mugs. All kinds of weirdness from the wacky world of M&M's. Definitely worth visiting!

Cute, well curated boutique of all things from the Harry Potter universe made by MinaLima. The ground floor is home to books, stationery, t-shirts, posters, enamel pins & more. Both floors are impeccably themed and styled. There are many genuine props from the HP films dotted around in cabinets too! The lower ground is home to the print gallery, where you can purchase limited edition prints of artwork created by MinaLima for the Harry Potter films. A must visit shop for Harry Potter fans.

A must-visit for Harry Potter lovers in or visiting London, loads of interesting museum for the lower level! With real HP movie props, and even some illustrated versions of the books! (Only 1 is out currently but can't wait to see the rest!)

No gallery like it 👌 visit this almost twice a week when I'm living in London, and it never ceases to surprise, comfort, and interest me. The energy of the building is humble, warm, and respectful of the works around it. It's always well managed, with attendants scattered around the building accordingly, offering some comfort that you'll not find yourself amongst hoards of loud teens etc The selection of portraits has remained extensive and broad, offering a wide variety for all tastes! Highly recommended this if and when you're in London!

A world class gallery. Totally worth seeing even just for the curation. One of the best galleries in London.
