An interview with Richard Arnold, Head of Technical Planning at Brand Metallbau AG and responsible for AURA. Together with his team, he works on continuously optimizing the frameless sliding window in terms of know-how, innovation and technical possibilities.
Richard Arnold: There are more complex considerations behind the frame than you would expect at first glance. AURA, the new product generation, is the result of over 20 years of expertise and innovation. We were able to draw on the combined knowledge and design details that we have gathered over the years together with industry innovator Marcel Ritzi.
Our active sealing system is a real highlight. It is absolutely impermeable to driving rain, storms and noise, while at the same time enabling filigree visible widths that were previously only possible with conventional sealing systems. Added to this is an improved sliding technology that opens and closes rooms effortlessly and almost silently - with enormous flexibility in the opening variants.
We have integrated many comfort options into the framework, such as ZIP screens for shading and temperature regulation, fully integrated insect screens or an electric drive. Everything is based on carefully selected materials and a strong manufacturing philosophy. We also test everything on our own test bench to ensure the highest level of precision craftsmanship - from design to assembly.
We rely on sustainable materials and production processes. The aluminum for AURA comes from regional sources with a strong focus on recycling and resource conservation. Our CO2-reduced production and in-house test bench guarantee not only the highest quality, but also durability. In this way, we make an active contribution to environmental protection and at the same time offer solutions that can withstand even extreme weather conditions in the long term.

With its active sealing system, AURA is 100% impermeable to wind, rain and noise and offers a straightforward design language with filigree face widths that were previously reserved for conventional sealing systems.
Operation is simple and convenient: air is introduced into the seals at the touch of a button to close the windows or doors. When open, the seals are fully rolled up, allowing the elements to be moved easily and effortlessly.
AURA has been certified by the Test Institute for Window Technology (ift Rosenheim) for the world's best tightness in all relevant categories. It combines a straightforward design language with world record performance.
AURA was awarded the world's best tightness in the following categories:
Driving rain tightness E 2100: Driving rain is a combination of rain and wind, where the wind creates pressure that drives the water into the seals.The window can withstand extreme rain conditions, even under high wind pressure.
Air permeability class 4: Absolute airtightness minimizes energy losses and guarantees comfort. The excellent airtightness of class 4 contributes significantly to the overall efficiency of the building envelope and supports compliance with strict energy standards.
Class 4 windows are particularly suitable for
Resistance to wind load E 2200:
Wind load resistance measures the ability of the window to withstand wind forces.
AURA withstands a test pressure of 2200 Pascal, which is well above the class value of the highest special class 5 of 2000 Pascal. This classification indicates an exceptionally high resistance to wind loads, which may be required for special applications or extreme environmental conditions, e.g. in high-rise buildings or coastal regions.
