Tenmat Vent Duct OverSleeve
Tenmat’s Vent Duct OverSleeve is a firestop penetration seal designed to fit around Semi Rigid PE Ducting that pass through fire rated partitions.
The OverSleeve is fire tested to EN 1366-3 in plasterboard partition walls and classified to EI120 according to EN 13501-2. The testing was carried out with Uncapped/Uncapped pipe end configuration as required for ventilated systems.
The low profile (4mm thick) OverSleeve is supplied flat and can be wrapped around the ducting and resealed with the reinforced foil backing tape. It’s design allows the product to be retrofitted to existing ductwork if needed.
In a fire situation, the OverSleeve rapidly expands to crush and seal off the duct to limit fire and smoke spread.
