Vent Duct OverSleeve

Tenmat’s Vent Duct Oversleeve is a firestop penetration seal designed to fit around Semi Rigid PE Ducting that passes through fire rated partitions.

PASSIVE FIRE PROTECTION

Firestop Penetration Seals

Semi rigid ventilation ducts are particularly susceptible to fire
attack and require a firestop that exhibits exceptionally quick
reaction to seal the duct before fire can pass through.

The Vent Duct OverSleeve is fire tested to EN 1366-3 in plasterboard partition walls and provides up to EI120 minutes fire resistance. The testing was carried out with Uncapped/Uncapped pipe end configuration as required for ventilated systems.

Black insulated pipe passes through a wall, sealed with a red firestop collar at the entry point.
A fire burns near a wall opening sealed with black material, with a red fireproof barrier visible above.
