brannskillende

Brannskillende is a Norwegian term that translates to "fire partition" or "fire wall." It refers to a structural element within a building designed to prevent or slow the spread of fire and smoke from one compartment to another. These partitions are a critical component of passive fire protection systems.

The primary function of a brannskillende is to maintain its structural integrity for a specified period when exposed to fire. This is typically assessed through fire resistance testing, which dictates the rating of the partition, often expressed in minutes (e.g., EI 60, meaning it resists fire for 60 minutes in terms of integrity and insulation).

Brannskillende can be constructed from various materials, including masonry, concrete, gypsum board, or specialized fire-resistant panels. The design and construction must ensure continuity of fire resistance across the entire partition, including any openings for services such as pipes, cables, or ventilation ducts. These openings must be protected with appropriate firestopping materials to maintain the integrity of the barrier.

The implementation of brannskillende is governed by building regulations and codes, which specify requirements based on the building's use, size, and occupancy. Their presence is crucial in ensuring the safety of occupants by providing safe evacuation routes and limiting fire damage to the building. They also play a role in containing fire to its area of origin, allowing time for firefighting efforts.
