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

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.
