Holding more than 60 years experience, Rationel employs 1,050 people in Denmark, England, Ireland and Poland; manufacturing premium quality, durable and stylish windows and doors.

Designed for a low-energy building style, the Scandinavian Rationel AURA window has a solid timber construction and the ability to attain high levels of solar gain. Featuring a sleek and minimalist construction, AURA is perfect for modern building with a contemporary design.

In terms of timber construction, the Rationel AURAPLUS window is identical to AURA. The only difference between them is the addition of external aluminium cladding included on the AURAPLUS window. This inclusion ensures both minimum and easy maintenance characteristics.

Both products have a wide variety of opening designs, glazing options and configurations. Along with the typical styles, this Scandinavian window can be manufactured in bespoke shapes to correspond to an assortment of openings. Featuring fully adjustable and secure ironmongery (Secure by Design part Q compliant hardware), two gaskets and the option of trickle vents; AURA and AURAPLUS are carefully engineered with the customer in mind. Furthermore, all Rationel products prioritise energy efficiency. The slim design naturally takes advantage of the solar heat from daylight, and the exceptional insulating qualities reduce CO2 emissions significantly.

Due to their energy efficient characteristics, both Rationel AURA and AURAPLUS are suitable for Passiv Haus buildings.

Thanks to constantly enhancing efficiency and optimising the products, Rationel windows are designed to withstand all weather types, attempted break-ins, and finally the constant wear and tear of repeatedly opening and closing windows year after year.

“We basically offer a complete service. For over 60 years our company has been based on excellent craftsmanship. This is still the case. At Rationel we take a pride in delivering high quality,” Rationel CEO Thomas Tvedergaard Larsen.
