The purpose of fire compartmentation is to to prevent the spread of fire to or from another part of the same building or an adjoining building. The compartment wall seperate the fire risk areas in a building (low, medium and high risk). The higher the fire risk in the area, the more fire resistant the compartment (30 minutes, 60 minutes, 90 minutes or 120 minutes). It also depends on the type of building and its height. Fire compartments are achieved by means of: Fire doors, curtains, shutters Fireproof partitions Fireproof ceilings Fire-stop closures Consult our professionals Do not hesitate to contact us, we can draw up an estimate together to find the best solution for your security.

Intufit® strips prevent cold-hot smoke from spreading when they reach a specified temperature during the fire. As Intufit® strips expand 20 times larger than their initial shape during a fire, they provide fire retardant properties. As a result of the self-adhesive applied on steel fire-resistant doors.
