Most partition walls contain interruptions, such as pipe and cable penetrations that fully penetrate the wall, but also interruptions on one side of the wall, such as electricity sockets. Such interruptions are weak spots when it comes to fire resistance. Promat walls are tested along with solutions for sockets and other common interruptions, and we offer a wide range of penetration seals for cable and pipe penetrations.
All the partitions are tested in standard configurations, but there are always differences between the tested specimen and the application on site. Some of these differences are covered by direct field applications or by engineering judgments, but it is often necessary to do specific tests. For example, the corners of the walls, the connections between wall and slab, sprinkler supports or shelves hung on the walls must be fire tested.
All these "details" play a key role in fire safety, and must not be underestimated. For years we have been at the forefront in testing complex and real-world configurations, and can provide several solutions for each specific case.
In practice one critical element of a non-load-bearing partition wall is the connection of the partition wall to the ceiling or floor above. This connection needs to provide for some movement due to possible deformations of the partition wall as well as the floor above during a fire, but at the same time remain closed against fire. We thus developed specific wall header solutions to make sure that this movement is accommodated and that the fire does not propagate.
