Rationel
Aura & AuraPlus

Rationel Aura is designed for clean lines, flat frames and a flush finish. This Scandinavian-style window has a solid timber construction and the ability to attain high levels of solar gain. Featuring a sleek and minimalist frame, AURA is perfect for a modern building with a contemporary design.
 
In terms of the timber construction, the Rationel AURAPLUS window is identical to AURA. The only difference between them is the addition of an external aluminium screen which is included on the AURAPLUS window. As it is constructed from two materials (timber and aluminium), the AURAPLUS is a composite window. This construction ensures that minimal maintenance is required and the aluminium-clad product has an impressive life expectancy of 83 years. In addition, the product has also been tested for use in marine environments.

  • At Enlightened Windows, we have worked with Rationel for more than 15 years in the UK and we are a Rationel-approved distributor nationwide. Rationel has more than 60 years’ experience of window manufacture and employs 1,050 people across Denmark, England, Ireland and Poland, crafting premium quality, durable and stylish windows and doors. Crucially, Rationel also has a very good UK support network and infrastructure. This means means that the product is reliable, spares are readily available in case of damage and the manufacturer guarantee is fully UK-supported and certificated. The importance of this should not be underestimated.

    Rationel Aura and AuraPlus Options

    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 with 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 significantly reduce CO2 emissions.
     
    Due to their energy efficient characteristics, both Rationel AURA and AURAPLUS are suitable for Passiv Haus buildings.

    Marine Suitability

    All aluminium profiles are coated with a minimum of 60 microns thick and are pre-anodized to achieve a marine-grade. The windows and doors will require regular maintenance, as per the Rationel Operations and Maintenance Manual, which is also included in the downloads tab of this page. Failure to maintain windows when in marine environments will result in failure of the product which is not warranted.
     
    Product development is primarily based on the Danish market and climate (i.e. predominantly coastal and similar to northern Scotland) so the products are ideal for coastal locations. We treat the aluminium for filiform corrosion prior to powder coating and the products are salt-spray tested at R&D stage. Furthermore, salt-spray batch testing is completed on all metal components from cladding to hinges.

    Efficiency, Solidity, Dependability

    Thanks to constant product optimisation and energy-efficiency enhancement by the company, Rationel windows are designed to withstand all weather types, attempted break-ins, as well as the wear and tear from opening and closing windows year after year. Rationel’s designs are not only tested on paper but are also physically tested and subsequently certified.

    “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 pride in delivering high quality,” Rationel CEO, Thomas Tvedergaard Larsen.
