Depending on the requirements for a workpiece or component, the standard - or the building authority approval authority - specifies the value for the required fire protection. In Switzerland, this is primarily the VKF (Association of Cantonal Fire Insurance Companies). These represent the fire protection regulations valid throughout Switzerland and the legal basis for the implementation of fire protection in buildings.
This results in the choice of material, which can vary according to the type of design. For higher quality interior fittings, cement-bonded panels - or for weight reasons - silicate panels are mainly used. These have the advantage that they have a high fire protection value and are relatively easy to machine. In contrast to gypsum boards, they have a higher compression in the edge area.
In interior or store fitting, modified chipboard is still used in some cases. These flammable boards comply with the B1 value and have the advantage that they offer hardly any problems in terms of weight and processing.
Gypsum-based boards are mainly used for wooden element construction or dry construction. These are much easier to work with, but must be finished by the plasterer or painter during further processing. Fermacell and Knauf offer a wide range of base materials, accessories and installation aids for this purpose.
For ceilings there are also fire protection panels and mounting systems.
