Aluduct AD-L flexible ducts are made from aluminium polyester foil
and reinforced with a helical coil of steel wire for better stiffness
and shape stability. This product is recommended for all ventilation
systems which require flexible connections between individual components.
It is most often used for connecting ductwork to plenum boxes and air valves.
It is also a popular option for building air exhaust lines which require
no thermal or sound insulation.
