A protective structure with a homogeneous, translucent shell was erected over the remains of the crematorium of the Sachsenhausen concentration camp near Oranienburg. The roof is a vacuum-stabilised membrane construction for which Werner Sobek was responsible for the facade engineering. Its supporting structure, which is not visible from the outside, consists of steel trusses and has an overall height of approx. 1.30 m in the roof area and approx. 1.15 m in the wall area.
Memorial with a Special Shell
On the outside and inside, the supporting structure is clad with a skin of grating and perforated sheeting. A translucent membrane made of a glass-fibre PTFE fabric was stretched over this construction and sealed airtight. To ensure reliable fixation of the membrane skin to the substructure, negative pressure is created between the two membrane levels.
