Hello, I have a problem with a plastic double-leaf window with a movable mullion, the right sash is tilt and the left one can only be opened, the problem is that during a strong wind in the upper left corner of the sash hinge you can hear a slight whistle of the wind and feel the wind blowing. It looks like a small pressure on the upper left corner because the window can be slightly tilted when it is closed. I also have the same problem with a tilt and turn window, it blows in the upper left corner, when the window is closed, you can also slightly tilt the upper left corner of the window. Nothing is blowing in the other windows and there is a strong pressure on the entire window. Can you tell me how to increase the pressure of this place and is it possible? The window is 7 months old, I will try to take and send photos soon.
Here I present photos, unfortunately I could not achieve better quality.
The left sash of the swing window, in this corner you can pull the window a little, at this point at the hinge it blows and there is a whistle of the wind

here I present two pictures of the same window only open

Here I present a photo of the second tilt and turn window in which also slightly blows at the hinge and there is a small pressure on the upper left corner.
