To do this, you need to unscrew two screws and then pull the ebb up and to the side.
You can see that there are many empty spaces under the window, which allows cold air to enter the room.
If there is no insulation between the outer and inner walls, then the cold will penetrate through this gap.
If there is a strip of foam on the ebb, cut it off, then process it with sandpaper, rub with a stiff brush, and finally you can wash it off under the shower.
Use a broom or vacuum cleaner to remove cement chips from the surface of the brick wall and purchase winter mounting foam.
First, fill all the cracks under the profile with foam, then the void between the walls, and also go over the outside with foam.
After such work, the ebb will be in place, and in three days the window sill will be warmer than at the beginning.
Drafts will disappear, and the air temperature near the window and in the room will become almost the same.
