Query: Astra Hammond window louvers

These are the two-piece louvers but match up nicely and the seam is barely visible. They do vibrate against the window some. I may have them stretched across the window more than intended. I think with a little silicone, adhesive or edging it would be easy enough to fix. I just haven't taken the time to do it.
