paloseinämien

Paloseinämien is a Finnish term that translates to "fire walls" or "fire-rated walls." In building construction, paloseinämien refer to walls specifically designed and constructed to resist the spread of fire for a specified period. These walls are crucial components of passive fire protection systems, which aim to contain fires within a compartment or prevent them from spreading to adjacent areas.

The fire resistance of a paloseinämien is typically determined by standardized tests that measure the time it takes for the wall to fail under fire exposure. Failure can occur due to several factors, including the penetration of flames, excessive heat transmission to the unexposed side, or structural collapse. Building codes and regulations often mandate the use of paloseinämien in specific locations, such as between different occupancy types, around stairwells and elevator shafts, and in multi-story buildings.

Materials used in constructing paloseinämien can vary but often include materials with inherent fire-resistant properties like concrete, masonry, or gypsum board with specific fire ratings. The assembly of these materials, including the type of insulation, fasteners, and joint treatments, is critical to achieving the required fire resistance. Regular inspection and maintenance of paloseinämien are essential to ensure their continued effectiveness.
