Hotel The Fontenay, Hamburg, DE
Glass and ceramics in the waves.
The Hotel The Fontenay impresses with a sophisticated design language and a radiant glass and ceramic façade. The GEWE-therm® sun sun protection glass from SCHOLLGLAS ensures a pleasant indoor climate.
The Hotel The Fontenay on the banks of Hamburg’s Outer Alster immediately catches the eye with its unusual geometric shape in floor plan and façade. The local architects Störmer, Murphy and Partners have made three interlocking circles the design theme and thus set an urban planning sign. Where the circles of the five-star hotel merge with each other, a glazed courtyard planted with trees forms the centre of the building.
The atrium gains its special atmosphere from the interplay of 198 satin-finished and scale-shaped glass panes that reach up to the roof. A semi-circular sofa with a length of 25 metres fits perfectly into the atrium. From here, the view sweeps up to the sixth floor, where the Fontenay Bar is located. The ground floor houses the reception, a restaurant and, last but not least, the elevators, which provide access to a total of 130 luxurious rooms and suites on the five upper levels, the spa area and a gourmet restaurant on the seventh floor. The hotel rooms usually describe trapezoidal floor plans with semicircular walls and floor-to-ceiling windows.

Sculptural, organic design
The outer shell of the hotel is defined by a façade that runs alternately concave or convex. Due to its sculptural, organic design, it placed special demands on façade builders and glass suppliers. Horizontal bands of glass and snow-white glazed ceramic plates in large format wrap around the building as if on an endless ribbon. The glass-ceramic façade was planned and implemented by Lindner Fassaden GmbH from Arnsdorf.
The construction of the curtain wall and rear-ventilated façade does not require massive supports. This is achieved by the static integration of the corridor walls and the radial wall bulkheads extending from them, which are load-bearing. The internal structure developed by the planners thus provides the necessary stability to realize dynamic curves and radii from 1.5 to 22 meters. The ceramic façade consists of 1,200 square metres of white glazed Longoton elements with panel heights of 40 mm and 614 mm. The substructure with brackets was pre-assembled accordingly to allow the façade panels to be hung in later without tools.
Multifunctional solar control glass
The glass surfaces, which were also installed from the outside, were mainly integrated into a mullion-transom system. Around 4,500 square metres of glass were produced and supplied for them by SCHOLLGLAS Technik GmbH Nossen. These are mainly triple insulating glass, type GEWE-therm® sun solar control glass from SCHOLLGLAS in various designs. A wafer-thin, metal coating reflects the solar radiation hitting the glass pane. This coating, which can consist of precious metals or metal oxides, is arranged on the outer pane towards the space between the panes.
In the Hotel Fontenay, the sun protection glass of the hotel rooms was made with the highly selective sun protection coating sunbelt A60 from Arcon. They achieve a Ug value of 0.6 W/m2K – with maximum light transmission. About half of the insulating glass panes are made of laminated safety glass (LSG) inside and out. In addition, toughened toughened safety glass (ESG-H) with edge enamelling was also used for the façade, which is due to the special requirements for the building. Thermal loads or exposed installation locations require individual solutions here. A special feature is the combination of edge screen printing with sun protection layer as part of a fixed-dimensional coating.
The highly effective solar control glass from SCHOLLGLAS meets the functional and design requirements desired by the client in the new Hamburg luxury hotel. In summer, they offer effective protection against overheating and pleasant temperatures in the interior. In winter, the glasses provide significant savings in energy costs.
