Rationel UK - Market-Leading Double Glazing from Panoramic Windows and Doors on Vimeo.

Rationel's continuous programme of research and development ensures that the company always meets current statutory requirements as well as market requirements for design and functionality.


The AURA range is constructed from solid timber offering all the beauty of a natural wood finish.

AURAPLUS timber composite windows also have durable exterior aluminium cladding, which provides extra protection against the harshest of weather conditions and requires zero maintenance.

Both AURA and AURAPLUS ranges offer a wide variety of different styles, colours and additional glazing options to suit your project.

For outstanding architectural elegance and energy efficiency look no further than AURA and AURAPLUS triple-glazed windows and doors. Their sleek, minimalist design and superb optical clarity is ideal for creating extensive glazed areas that let in maximum natural daylight for a pleasant modern living environment.

With its high-performance triple-glazing, AURA and AURAPLUS can easily achieve the Passivhaus standard of energy efficiency, dramatically reducing your CO2 emissions and energy bills.


Forma & Forma Plus are the new concepts from Rationel that provide a traditional look for your new or renovation project. Today, period and classic houses can also be refurbished to enjoy the advantages of energy efficient windows.

Our FORMA range consists of all-timber windows with slim, non-continuous bars.

The FORMAPLUS range is similar to the FORMA range, produced with the same solid timber construction. The only difference is that FORMAPLUS is provided with external aluminium cladding attached with clips, ensuring minimum maintenance. This product range is also ideal for new build if a classic expression is desired.

FORMA and FORMAPLUS are available both with and without glazing bars. To fit in with your design, we have a variety of different glazing bars. Terrace and entrance doors with glazing and wooden infill panels are also part of the range. They are easy to join in multiples and therefore suitable for complex window solutions.
