Paloseinämiä

Paloseinämiä, often translated as fire walls or fire partitions, are essential structural elements designed to compartmentalize buildings and prevent the spread of fire. Their primary function is to slow down or stop the passage of flames and smoke from one area to another, thereby giving occupants more time to escape and firefighters more time to intervene. These walls are constructed from materials that are inherently resistant to fire for a specified period, commonly measured in minutes or hours.

The effectiveness of a paloseinämiä is determined by its fire resistance rating, which indicates how long it can withstand exposure to fire without failing. This rating is established through rigorous testing by accredited laboratories. The construction of these walls typically involves layers of non-combustible materials such as concrete, masonry, gypsum board, or specialized fire-resistant insulation. They must be continuous from floor to ceiling and extend through any adjacent structural elements to maintain their integrity.

Proper installation and sealing are critical for the performance of paloseinämiä. Any openings, such as those for pipes, ventilation ducts, or electrical conduits, must be protected with fire-stopping materials that maintain the wall's fire resistance rating. Doors and windows installed within fire walls must also be specifically designed and rated for fire resistance. Building codes and regulations in most jurisdictions mandate the use of paloseinämiä in specific locations, such as between dwelling units in apartment buildings, in commercial structures, and in industrial facilities, to enhance overall life safety.
