An undesired event during the lifetime of a building is fire. Unfortunately, this situation can occur. Therefore, it is advisable to take all necessary measures to prevent fires and to stop their spread.
Current construction standards (SR EN 1996 1-2) provide the criteria that masonry walls must meet in case of a fire and are measured in minutes.
These refer to resistance that a wall must have until it fails, the airtightness it must ensure (the property of not allowing smoke to pass through the walls), and insulation (not transmitting heat between rooms, as certain materials can self-ignite at high temperatures).
The criteria are provided for the safety of residents (to allow sufficient time for evacuation of the building), to minimize damage, and to prevent noxious fumes that could lead to poisoning during fires.
Brikston brick falls into the highest class regarding fire reaction: Euroclass A1. It is practically incombustible, preventing the spread of fire and maintaining its load-bearing capacity at high temperatures.
