Electrical and data lines or similar installations can be installed very easily and discretely in gypsum blocks, both immediately after erecting the wall and also subsequently with later reconstrcution or conversion.
Routering for cables are made using a scoring tool or pipes or by machining out. A drill bit is used for electrical sockets. Under no circumstances chisel out slits and socket holes. With the placing of the installations only corrosion protected securing fixings are to be used. Subsequently the slits are so closed using gypsum mortar that there is a sufficient covering of the component, which should be at least 1 cm.
They do not prejudice the stability of the wall so far as they correspond with the geometric constraints.

Taking into consideration the constraints for the pipes can also be laid in partition walls made from gypsum blocks. In each case metal pipes must be protected against corrosion. In order to avoid condensed water and the formation of cracks as a result of heat expansion, the pipes should be suitably lagged.
Pipes within the cross-section weaken the acoustic insulation of the partition wall therefore laying using sound dampening fixtures on the wall is usually more favourable. It is then recommended to implement the partition wall as double-leaf installation wall made from gypsum blocks with or without a facing.
Even when partition walls made from gypsum blocks have to meet fire protection requirements, electrical sockets, switches and distribution boxes can be installed at any desired position, which may not, however, lie immediately opposite each other.
Individual electrical lines may be fed through the wall whereby the remaining cross-section is to be filled completely with gypsum mortar.
If several electrical lines are passed through the wall at one position or other penetrations are planned, these openings, as for door openings, must have closures which satisfy fire protection requirements. These can, for example, be fire protected doors, fire protection or access covers, fire retarding sealing of lines or fire protection glazing.
