FIELD: construction.
SUBSTANCE: ventilation panel made of multilayer material comprises a layer having the first hole and adjacent layer having the second hole. Besides the first and second holes do not match with each other and are not substantially overlapping, forming ventilation channel. At the same time this channel mutually joins the first and second holes, thus providing for passage of fluid medium both from hole to hole and through ventilation panel outside. Device also comprises insulating channel connected to one of holes, thus providing for insulation as a result of fluid medium passage along and inside of insulating channel. Invention also relates to ventilation system, method of ventilation panel manufacturing, and also to method of box manufacturing and to insulating panel made of multilayer material. Besides application of this panel is also possible in other areas of equipment, where it may be useful.
EFFECT: creation of ventilation panel, which preserves heat of hot products and prevents formation of undesirable moisture inside package.
