What is firesealing – and thy is it important?

Firesealing is about preventing fire and smoke from spreading in a building before it has been evacuated. Firesealing reduces the risk of major collapses and serious damage – to materials and to people. Firesealing is therefore of the utmost importance.

When you fireseal, you secure spaces for a specified time. This means that you make sure that an enclosed space can withstand a fire for a specific time. How long is already determined at the design stage. By covering cavities and penetrations made for pipes and cables, for example, a so-called fire cell can withstand smoke, gas and flames for the time needed to evacuate the space.
