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