The flexible Aluduct AD-L duct is made of aluminum-polyester foil, reinforced with spirally wound steel wire, which stiffens the duct and gives it the appropriate shape. It is recommended for ventilation installations where flexible connection of elements is required. Most commonly connected to plenum boxes or ventilation valves. It is primarily used in exhaust ventilation systems where thermal or acoustic insulation is not necessary.
