Fabric ducts completely permeable are designed for cooling the rooms. While using them for heating purposes, the occurrence of the air temperature layer separation is possible. Such problem may occur, however, only in the facilities with large cubic capacity (particularly in places where the ducts would be erected at the height above 4,5 meters) and in such facilities it is recommended to use the ducts with nozzles or blowing gaps for heating purposes. Through nozzles and gaps we lead to intensification of the air outflow, additionally directing that stream e.g. downwards so that the air supply zone would include the lower levels of the hall as well.
