Whatever your project, whether it’s new build or refurbishment, a single house or a major urban regeneration scheme, Rationel is the natural choice.

Rationel have been designing and manufacturing quality windows and doors for over 50 years and have successfully completed thousands of projects.

In that time we have developed a complete range of classical and modern styles, in timber and composite timber clad aluminium, both of which are available with double or triple glazed Low-E glass. We can also offer you a wide variety of opening solutions, from side hung to tilt & turn to top hung with fully reversible hinges. Our entire range is available in over 250 colours in addition to four traditional wood stain finishes and to make sure we can always give our customers what they want – we offer a made-to- measure service.

The constant evolution of a simple product has become an irreversible tradition at Rationel and central to the identity of the entire company. Our role is simple – to make the best products we can so as to enable you to create a healthy environment and bring daylight and fresh air into people’s everyday lives. We invite you to visit our stand where many of our products will be on display.
