Thanks Jeffrey. I mean, my installer filled the full foam between window frame and wall (see picture below) but my friend's installer only fills 4 corners of window frame to wall with a lot space left. Let me see if I can get a photo.

You need to fill it with foam but what do you meant by 填满？it is for insulation purpose. This is basic.
