Tulenseinät

Tulenseinät, which translates to "fire walls" in English, refers to fire-resistant barriers used in buildings to prevent or slow the spread of fire. These structures are crucial components of passive fire protection systems. Their primary purpose is to compartmentalize a building, dividing it into smaller, manageable sections. By containing a fire within a specific area, tulenseinät give occupants more time to evacuate safely and allow firefighters to work more effectively.

The construction of tulenseinät involves using fire-resistant materials such as concrete, brick, plasterboard, or specialized fire-rated panels. These materials are chosen for their ability to withstand high temperatures for a specified period, often designated by a fire-resistance rating (e.g., EI 60, meaning it provides insulation and integrity for 60 minutes). Any openings in a tulenseinä, such as for pipes, cables, or doors, must also be protected with appropriate firestopping measures to maintain the wall's integrity. This includes using fire-rated doors, dampers, and sealant materials.

Tulenseinät are a fundamental requirement in building codes and regulations in many countries. They are typically found in various types of buildings, including residential, commercial, industrial, and public spaces. Their strategic placement in stairwells, corridors, and between different occupancies helps to limit the damage and risk associated with fire incidents, ultimately contributing to the overall safety of the building and its occupants.
