Shaft wall panelling

"Flame retardant" ≠ "Incombustible"

Important planning information for our customers!

In the building regulations of the German federal states, buildings are divided into different building classes ( 1 - 5 ). Most lifts are installed in buildings of building class 5 (height >13m and/or usage units with more than 400m²).
According to the building regulations of the federal states (which are very similar or almost identical in all federal states) lift shaft walls are considered as space-enclosing components and must be fire-resistant and made of non-combustible building materials. This corresponds to fire protection class A1 according to DIN 4102.

The W+W shaft wall panelling made of hot-dip galvanized sheet steel (building material class A1) meets these requirements, fire protection class A1, non-combustible and can be installed without any restrictions.
The use of rigid foam mats consisting of polyurethane (building material class B1) or similar materials is rather problematic. They belong to fire protection class B1 (flame retardant) according to DIN 4102 and must not be used in the lift shaft.

Please consider these specifications when planning a shaft wall panelling.

Mounting

Description

Width of the steel sheets: 1000 or 1500mm
Height of the steel sheets: 100 or 120mm

The horizontal distance between the inner shaft wall and the door sill or the door frame of the car or the closing edge of a sliding car door must not exceed 0.15m over the entire shaft height.
The distance indicated above may be scaled up to 0.20 , if the height does not exceed 0.50 m. Between two successive landing doors there must not be more than one recess.
If these dimensions are exceeded, a shaft wall panelling is necessary. The shaft wall panelling consists of 1.5mm hot-dip galvanised sheet steel and it is available in two sizes. The metal sheets can be stacked into each other and therefore can be transported easily. With the extension sheets a continuous surface between two doors can be realised. With the flat tapping screws (Art.no. 50781) a safe connection of the individual sheet metal parts is possible without problems.
