Compartmentalisation can be compromised by ventilation and smoke extraction ducts. It is therefore necessary that they have the same fire resistance as the compartmentalising elements.

Fire-resistant ducts are the best way to ensure fire safety, as they provide fire resistance and prevent the spread of fire.

Fire resistance in ducts is a mandatory requirement when they pass through walls or floors that function as fire compartments.

The fire resistance tests of the ducts are carried out under standard EN 1366-1 for ventilation ducts and under EN 1366-8 for smoke extraction ducts. The ducts are tested on the basis of the following criteria:

Type (rectangular or circular).

Alignment (horizontal or vertical).

In the case of ventilation ducts, type of fire (exterior or interior).

Perlita y Vermiculita, S.L.U. offers solutions against fire for the protection of ducts, both for ventilation and smoke extraction.
