I have standard window shades installed on a few windows. The shades are pulled all the way down. So any air that escapes from behind the shades would have to leave either on the sides or the bottom of the shades.
The temperate outside has been around 30-40 degrees F cooler than inside. If you touch the window glass, it feels noticeably cold. If you put your face directly in front of the bottom of these shades, you can feel an almost constant slight breeze of cool air. Now if you move away from the window, say 1 foot away, you can barely feel the air flow anymore if at all.
Is it possible for a natural draft (the colder air near the window, dropping down below the warmer air) to create this constant air flow?
I can't quite figure out if there is a subtle air leak or it is just a natural draft. The rooms with these windows do feel cooler than others inside.
Thanks.
