FIELD: construction.
SUBSTANCE: windowsill is proposed, containing a windowsill plate consisting of a base and a heat-insulating layer with a surface layer. Moreover, the base of the windowsill plate contains at least one air infiltration channel, which has an input part from the side of an outer medium and an output part from the side of an inner medium. A through hole is made in the windowsill plate, in which at least one ventilation grate is placed. At the same time, at least one fan is fixed to the base under the through hole of the windowsill plate, and a removable filter, on which and partially on the windowsill plate a heat window profile with an outer slope is installed, is placed from the side of the input part of air infiltration channels from the outer medium.
EFFECT: increase in the quality of microclimate by means of creation of a possibility of room ventilation and direct mixing of fresh air with convection flows from a heating device.
