The task

When standing on the Elphi-Plaza overlooking the Elbe or listening to brilliantly presented sounds of music in the concert hall, you will surely not think of how many passageways you have passed on your way there.

In a building such as the Elbe Philharmonic Hall first-class products are not only installed where they are visible and aesthetics matter, but everywhere. You will be forgiven for not considering the mundane, like safety and security. In a concert hall with an auditorium capacity of up to 2,100 spectators the escape routes for instance require time-consuming planning.

In such a superlative building interior design in every detail counts. Thus, the doors are chosen for their functionality and for their aesthetic criteria: Fire protection and smoke protection have to be harmonised with the creative objective of a flush finish.


The solution

Special block frames with rim widths up to 625 millimetres for two-leaf doors that have the exact same depth as the wall. This also made individual approvals necessary in most cases. It's time-consuming, however in the end it worked out smoothly as our doors in their standard versions are proven fire protection doors.

Although the doors may show uniform visual appearance: their functions are very different. Depending on their position they are one-leaf or two leaf versions, as T30 or T90, some with and some without smoke protection. Where special sound insulation was required, special fastening material had to be used. Approximately one sixth of the doors are opening automatically and around 40 percent of the doors are connected to the access control system, to the burglar alarm system or the central smoke extraction system. To keep escape routes for people with special needs clear, some fire protection doors are mandatory to open automatically. These solutions are the reason our products are named "door solutions“. In total there are 15 different frame versions with identical visual appearance!
