Rationel AURA Timber Window Range

Our new ‘energy-contributing’ Rationel AURA windows offer the same excellent properties as Rationel AURA+, but these windows are made entirely from timber. You can therefore combine a beautiful natural look with a clean contemporary design for modern buildings and Passiv Haus. Rationel AURA ensures that high levels of daylight and solar heat gain are achieved.

Opening Types

Top Guided

Top Guided windows are a simple, elegant and user-friendly design. Opening is controlled by tracks and slides. When opening the window the top of the sash slides downwards as the bottom of the sash opens outwards. Adjustable friction ironmongery allows an almost infinite choice of open positions.

Side Hung

Side Hung windows are controlled with tracks and slides. On windows over 424 mm wide, the handle controlled friction brake allows the window to be fixed in any open position.

Side Guided

Side Guided windows are controlled by tracks and slides that allow the window to be fixed in any open position. However, when opened, the hinge side of the sash moves toward the middle to create an opening that allows the glass to be cleaned from the inside.

Top Swing

In everyday operation the fully reversible window functions as a Top Guided window. However it is possible to turn the sash through 170 degrees to clean the glass from the inside.

Fixed Light

Fixed Light windows are ideal wherever maximum internal light and solar heat gain is required.

Colours

When choosing windows and doors from Rationel, it is possible to enhance the appearance and character of your house through your choice of colour. Our standard colours suit the majority of architectural styles and traditions in the United Kingdom. We also offer a special range of colours, which you can use to highlight particular features of your home.

Standard RAL Colours

Rationel AURA and Rationel AURA+ windows and doors are available in one standard colour on both the inside and outside of the frame. It is possible to have a split colour solution on Rationel AURA+, where you are able to have a different colour on the outside to what you choose for the inside.
