Marvin Casement exterior ?
When we are looking at the Marvin windows on display I noticed that when the casement window was open the whole perimeter of the window has an opening like a tunnel where IMO dirt, gunk and grime will collect. My Anderson's only have an open are where the locking clips go in when the window is closed. Just curious to know if anyone else has issues with this? Also don't care for the black weather stripping on a white window.
