Jeldwen would be that high on the list?

Oberon always has a very nice way of delivering bad news.

Yes he does! thank you.
One of the windows needs to be a pass through - I don’t see Marvin giving me that option on the website.
Anderson has
That window can be a French style but will need to open flat against the wall.
Any suggestions with Marvin?

A push-out French casement would be my first thought, but not sure if they are able to open 180° or not. You need to find out from Marvin.

You might also look into Kolbe, they offer pretty much everything Marvin does so maybe they might meet your requirements.
