Installation shaft EI 90 / fire protection wall

The FireDuct installation shaft consists of self-supporting, mutually rebated elements made of glass fiber reinforced lightweight concrete - fire protection panels.

Thanks to this construction, a homogeneous, extremely slim and stable wall construction with a wall thickness of only 50mm is achieved, which therefore requires no further additional substructures.

After the usual pre-treatment, the installation shaft walls can be painted, plastered or covered with ceramic tiles.

FireDuct fire protection wall

The FireDuct partition wall construction for shaft walls can be manufactured with a fire resistance of 30 to 120 minutes. Aestuver fire protection panels are used for the FireDuct fire protection walls, which can also be used in highly humid and climatically stressed areas. With the use of FireDuct fire protection walls, the highest fire protection requirements can be combined with visually appealing design. The FireDuct fire protection walls are mainly used in fire protection-performing dry construction systems in interior areas, where high sound insulation requirements must be met at the same time.
