heroal Systems in 'the niu Tab' Hotel | heroal

In the hotel the niu Tab, completed in 2021, Japanese culture meets the undeniable 'joie de vivre' of the Rhineland. The colour-coordinated lifting-sliding door systems heroal S 77 SL, window systems heroal W 72 and door systems heroal D 72 set the perfect scene for urban life, emphasising the international mindset of the city on the river Rhine with their timeless design, great flexibility, perfect functionality and visual appearance. The versatile aluminium system solutions from heroal fit perfectly into the concept of a high-quality, yet restrained building architecture of the Hamburg-based architects SKAI, Siemer Kramer Architekten Ingenieure Partnerschaft mbB.

Thanks to its functional architecture, the hotel building with 438 rooms on 13 floors blends into the urban surroundings, not far from Düsseldorf’s central railway station. The u-shaped hotel complex with a gross floor area of 22,000 square metres rises almost 40 metres into the sky in the highest part of the building, flanked by two flatter building wings with six and seven floors respectively.

Large glass surfaces create an entrance area flooded with light and provide for a view of the green spaces beyond. From the terrace, guests have a nice view of the public park, while the rooms on higher floors offer a view of the city.

Due to the central location on a main road, special sound insulation requirements had to be addressed during the planning of the hotel, so that the hotel guests would not be disturbed by loud external noise. For this purpose, the required weighted sound reduction indexes were determined, accounting for potential component fluctuations. The company Wigger Fenster + Fassaden GmbH relied on the window system heroal W 72, which provides for an identical look for windows with different soundproofing classes from 1 to 5. On the side facing away from the street, towards the inner courtyard and public park, heroal soundproof windows with an Rw,R index of 30 dB were installed. The building parts exposed to more noise were fitted with heroal soundproof windows with Rw,R indexes of 40, 43 or 44 dB, as required.
