Accessible installation shafts

Business Campus in Garching

Accessible installation shafts needed to be separated with a fire-resistant partition at the Business Campus in Garching near Munich. To meet this need, 60 PRIODOOR ETX inspection flaps were installed in the stairwell. The unique feature of the project were the lowering floor seals and doors with three-sided frame. The Business Campus chose a real wood veneer surface in American cherry.
