Secondary Glazing for Listed Buildings Chelsea

Sash Windows (Vertical sliding) Chelsea
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 Chelsea
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 Chelsea
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 Chelsea
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.

We had a great time exploring this historic house. It’s exactly like stepping back in time. The staff were also kind enough to let us wander at our own pace, as I find it’s a problem at other historic sites.

I was transported back in time. If you are interested in history, and like me are drawn to old houses this is a gem. Not to be missed. A lot of information around the house. The guides were super friendly. Amazing this house and all it’s furniture has survived to today.

Beautiful house with interesting interior - a great place to visit, even if you have no idea who Carlyle is. The staff is more than willing to give you tons of information.
