Superior strength and slimmer sightlines

We offer a choice of aluminium window systems, including ALUK, Evoke Flush Aluminium, Sapa Crown, Smarts Heritage and Origin. Despite the higher price point than uPVC, aluminium is an increasingly popular choice - it works particularly well in both traditional and modern contemporary applications. With slimmer profiles than uPVC and virtually maintenance free, our aluminium windows are available in a wide choice of colours, including dual colours. The system is fully weather stripped to achieve the highest levels of weather performance and all profiles incorporate polyamide thermal barriers to meet the latest Building Regulation requirements in terms of U values and window energy ratings.

Let the light shine into your home

With quality and innovation at its heart, our aluminium window and door systems improve the way we live our lives. Combining high performance design with elegant and innovative features, our aluminium glazing systems offer optimum comfort with maximum security.

For many years both Crown and ALUK have been developing windows and doors specifically for the UK market, answering the needs of homeowners and offering them reliable and low maintenance solutions that improve their living environment and add value to their home. With stylish and attractive products to suit any property, our comprehensive range brings together innovative design, a wide range of finishes and the highest standards in security and performance to make your home comfortable, safe and secure.

Over 400 colour options

Our aluminium windows use ‘True Dual-Colour‘ technology affording a palette of over 400 colours for the inside and outside of your windows, to blend or contrast with your home as you wish. The finish is a high performance, non-fading, hard and durable coating that is baked onto the frames. Being low maintenance, it needs only an occasional wipe down to stay looking as good as new.


Modern and traditional styles

Sustainable aluminium offers a complete range of window styles to complement your home, from traditional to ultra modern, allowing you the choice of a reliable and attractive finish. For contemporary installations, aluminium is always the preferred choice - wide expanses of glazing can be achieved to create a relaxed and comfortable living environment for you and your family to enjoy. And, with minimal maintenance and full guarantees, you can rest assured that you are installing the most reliable windows available.

Your windows can be finished with an inspiring array of Georgian, leaded, patterned or stained glass highlighting distinct aspects of your home to add character, style and privacy.

Perfect for both the traditional and contemporary home

The Alitherm Heritage ranges were designed specifically to meet the requirements of refurbishment and renewal projects, particularly in sensitive planning areas. Featuring slim, thermally-broken profiles, Alitherm Heritage windows and doors are available in a number of formats, including fixed-pane, sash, top-hung and side-hung casement, pivot and tilt and turn. These different options may be installed in a combination of horizontal modules, which are stacked using coupling options to form a multi-part window which can be installed both as an internal and external window and door system.
