Modern or Traditional? Choosing Your New Rationel Windows

Whether you are looking for a contemporary or classic feel, Rationel windows help to bring light, beauty and warmth to your home. The Scandinavian designs come with various customisable features, such as colour, glazing, and opening and closing functions.

There are two signature styles: Rationel AURA/AURAPLUS and Rationel FORMA/FORMAPLUS. Rationel AURA/FORMA styles have timber frames with a 60 year life expectancy, whereas PLUS styles have an aluminium clad timber frame, helping to increase durability and the window's life expectancy by 20+ years.

Maximise daylight with Rationel AURA/AURAPLUS windows; these sleek and modern designs are minimalistic, utilising clean lines. If you're looking for a more traditional aesthetic, you may prefer the unique detailing on Rationel FORMA/FORMAPLUS windows.

The stunning Rationel doors are created with durable, high quality materials that are thermally efficient. The doors also have excellent acoustic properties, making them suitable for a wide range of projects.
