Rationel windows

Fixed light windows

Bring the outdoors in with our elegant fixed light window designs. For maximised daylight and to enjoy the best views of the surrounding scenery, there can be no better choice for homeowners.

Because of the window style, this window creates the largest possible glass area. The result is maximised levels of daylight, as well as increased views of the beautiful scenery outdoors.

The glass of our fixed light window is inserted directly into the frame, meaning their function is not to open, but to let more natural light and warmth into your room. With a larger area of glazing and slimmer window frame, this makes them perfect for those countryside lodgings.
Every single one of our windows is made bespoke from sustainably-sourced materials. The aim is for them to last for generations. With over 200 colours to choose from and a range of glazing options (including toughened and acoustic glass), your windows can truly become your own.

Simple style that allows for optimal views. Ideal when you need maximum internal light and solar heat. Can be fitted with trickle-vents for ventilation.

More about Rationel windows

Windows done the right way

The ideal glass for every location:
 
Frosted or patterned glass

Designed to reduce transparency, Rationel OBSCURE glass is the ideal choice for any room where both privacy and natural light are essential, such as a bathroom.

Acoustic control
If you live in a big city, near a busy road, or close to any source of noise, Rationel SOUND glass offers great acoustic control, helping absorb sound and improve the comfort of your home.


Solar control
Designed to minimise solar gain – free heat from the sun – Rationel SOLAR glass is the ideal choice for south or west facing windows or facades, to help ensure a comfortable temperature in every room.


Security glass
Difficult to break, Rationel SECURE glass features laminated panes designed to deter even the most persistent burglar. Rationel SECURE glass has been tested in accordance with several national and European safety standards, including those that give certification under Secured by Design. For maximum performance, specify alongside the full range of Rationel security features.

Coloured glass
Choose from a wide range of Rationel FACADE standard colours (plus additional shades on request) to add visual impact and special effects, or to create coloured glass panels across floor slabs, for example.

Safety glass
Toughened or laminated – or a combination of the two – extra-strong Rationel SAFETY glass is designed to break safely in order to minimise risk of injury, and has been tested and marked according to several national and European standards.

The ideal colour choice for your windows depends on many different factors – here are five things to consider:

  • Building style – modern or traditional?
  • What colours are used nearby?
  • Do you want a granite finish or RAL colour?
  • What colour is most practical for your project?
  • Do you want different colours inside and out?


RAL Colours for windows and doors

RAL paints use an industrial colour matching system developed in Germany in the 1920s and which is now globally recognised. The RAL Classic scale comprises 210 four digit colour codes which ensure precision when choosing a specific shade. Rationel windows and doors can be specified in any RAL Classic colour, and for both timber and aluminium frame elements. A wide range of RAL Classic colours are available as standard – non-standard colours may be subject to additional costs and lead times.

Granite colours

For a different finish on external aluminium frames, choose from six beautiful granite colours. A granite frame has a natural and more ‘rustic’ appearance, and is also highly practical thanks to its dirt-repellent surface.
