Our windows are precision engineered, created in our technically advanced factory, where we have over £500k of fully automated, computer numerically controlled (CNC) machining equipment. Because of this and because of our attention to detail, our factory is widely regarded by professionals in the window trade as one of the best in the UK.  Each window is hand-finished and undergoes a full quality inspection before being wrapped, prior to being shipped on our own fleet of lorries.

There is a huge range of colour and finish options and we can easily supply your windows in a different colour inside and outside if you wish, which we call dual colour. Design your window to be top hung, side hung or simply specify a fixed window (non-opening) and as most people choose open-out windows, it means they don’t interfere with your curtains or blinds. In-glass blinds are now a popular choice too.

Schüco Aluminium Windows are fully compatible in design and specification with KAT Schüco ALuminium Bifolds and Patio doors, all supplied with the comfort of a 10 Year guarantee.

Blinds Within Glass


Integral venetian blinds are designed specifically to sit neatly inside a sealed glass unit, between the panes of glass. A totally maintenance free option, they allow you to discard dust attracting curtains or roller blinds. They are utterly contemporary, available in a choice of 10 colours; White, Yellow, Hay, Sage, Sky, Cream, Putty, Silver, Dark Silver and Dark Grey. 

Raising and lowering integral blinds is controlled using either Rotational Wands or Knobs, or a Cord system, also by Solar Powered units or by powering them via your mains supply. Our blinds carry a 5 year guarantee, are maintenance free, conform to BSEN 13120 Safety Standards and are suitable for 28mm double glazed window sashes, up to 1200mm wide.

Material Information


Aluminium is the world’s most abundant metal and is the third most common element, comprising 8% of the earth’s crust and has a strength to weight ratio superior to steel.  The excellent strength to weight ratio of aluminium has made it an important material for the construction of aircraft, ships, many cars and also commercial vehicles.

When the surface of aluminium metal is exposed to air, a protective oxide coating forms almost instantaneously which gives excellent corrosion resistance. This oxide layer can be further enhanced with surface treatments such as anodising. It is widely recognised that aluminium is the best material for making windows and doors from, when they are to be installed in marine environments.

The recyclability of aluminium is unparalleled. When recycled there is no degradation in properties when recycled aluminium is compared to virgin aluminium. Furthermore, recycling of aluminium only requires around 5 percent of the input energy required to produce virgin aluminium metal. Currently around 60% of aluminium metal is recycled at the end of its lifecycle but this percentage can still be vastly improved.




Furniture for our Schüco Aluminium Windows can be manufactured in austenitic steel which is a marine grade finish for coastal applications. Our standard ‘bespoke to KAT’ range is perfect for most domestic applications of course.

Check out the finishes on our handles because it is our attention to detail that helps make this unique product range so appealing.

Handles are available in:

  • Anodised Silver
  • Black
  • White
