Sash Windows (Vertical sliding) Millbank
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 Millbank
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 Millbank
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 Millbank
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.

After up 8 floors in lift... Sorry, closed for private function all day! A sign on the ground floor would have been considerate? Serendipity... found Sea Containers close by... pleasant drinks, food and position excellent 😊

It's a gallery with as you would expect lots of paintings that are well presented in a clean and orderly manner. We went during the school holidays and it was a lot quieter than expected although it's not really a place to bring younger children. The tea and chocolate brownie from the restaurant were delicious by the way

It's a lovely museum which usually is on the quiet side on week days. Their collection of paintings and sculptures, along with their curation, is very good. I'm always less impressed by their twist on modern and contemporary art which is borderline British kitsch in taste and barely relevant or interesting. Lovely otherwise. Shop also good with lots and lots of books.
