The heat-insulating valve of the ventilation device can be made of foam coated with an insulator and can have a rectangular profile, which provides convenient insertion of the specified valve into the device body and its movement along the width of the body. In addition, the use of foam and isolon as the materials of which the valve is made allows the full use of the unique properties of these materials, namely the low thermal conductivity of the foam and isolon ensure reliable temperature storage in a ventilated room, as a result of which there is no increase in energy consumption, required for heating and / or cooling ventilated rooms. In addition, isolon and polystyrene are environmentally friendly materials that do not emit substances toxic to humans or the environment, do not irritate mucous membranes and do not cause allergies, which ensures installation and use of a heat-insulating valve of a ventilation device that is safe for humans and the environment. Isolon and polystyrene are also good waterproofing materials that provide effective protection over their entire volume from moisture and water vapor, which can penetrate along with the air flow into the cavity of the housing of the ventilation device, which makes it possible to maintain air humidity maintained in a ventilated room. Isolon and polystyrene are also effective soundproofing materials, which reduces the level of external noise penetrating from the street through the housing of the ventilation device into the ventilated room. The implementation of the heat-insulating valve made of foam allows the fire to be prevented from spreading inside the ventilation device case and its subsequent penetration into the ventilated room when the device ignites from the street side, due to the fact that the foam does not support combustion and has a low combustion temperature, while releasing a small amount energy. Moreover, the foam has a high resistance under uniform mechanical stresses, both in tension and compression, and has a low density, so that the installation of this valve in the housing of the ventilation device increases its strength and does not significantly affect the total weight of the specified device, which simplifies its transportation and installation. In addition, the isolon covering the foam from which the heat-insulating valve is made is a light and flexible material that is lightweight and has a long service life without losing its properties, which ensures the simplicity and high speed of installation of this material. Since the isolon is produced on the basis of polymer raw materials, it has an increased microbiological resistance and, therefore, is resistant to decay, which ensures that when moisture is deposited on a heat-insulating valve, it is possible to prevent the appearance of an unpleasant odor from a ventilation device in a ventilated room. In addition, the use of isolon as the top layer of a heat-insulating insert provides the possibility of partial cleaning of the air flow penetrating into the device from dust and other fine particles that will settle on the surface of this material.

The case of the ventilation device can be formed by the bottom, ceiling, two side walls, the front wall facing the side of the ventilated room, and the back wall facing the street. The side walls of the ventilation device can be made hollow and removable, which makes it possible to reduce the total weight of the device, the possibility of placing additional structural elements of the device in the cavity of the indicated side walls, the ability to clean and replace the side walls and the possibility of access from the respective sides to the structural elements placed in the cavity device housings, for possible cleaning and replacement.

In a preferred embodiment, the profile of the back wall of the ventilation device has a trapezoidal protrusion, and the side of the profile facing the surface of the earth contains at least one air inlet. Such an arrangement of said at least one air intake opening 5 provides the possibility of preventing the penetration of precipitation, leaves and other pollutants through it into the device body.
