double or single hung window for ventilating interior room with 16" OC studs

I'm looking for a double or single hung window to fit between 2x4 16" OC interior studs. Or some other idea to enable ventilation between two rooms and still allow for privacy. I don't want to mess with the studs as they are bearing. I don't recall seeing this before and the standard window sizes tend to begin at about 18" minimum width; I'd be looking at more like 14 1/2" wide, I believe. I don't want just a door panel or fixed louver kind of thing; I need to be able to close it tightly and not protrude when open, and also have some nice appearance.

All ideas greatly appreciated.

 

There are basically no "standard" window sizes. Box stores and suppliers will have a stock of commonly used window sizes for convenience only. If you go to a window store (Jeld Wen, Pella, Andersen, etc.) You can give them the specifications you need for a window and they can have it made within 2 weeks normally. No window is ever made until an order for a size is requested, so don't think it is a "special order". I do this every time I have a window installation project.

As far as double or single hung, I have seen little use in double hung windows, since you can't open but half of the window at a time. Depending on your situation, a casement window will give considerably more ventilation over a double/single hung window.

Now that I have read your post again, is this for an interior wall???

 

As Larry says there are no standards per say. All are made to size. You might check an RV supplier. I also assume its an interior room. When you say it needs to be closed tight, just how tight? Any window will not provide sound from coming through. Double pain is not reasonable for an interior situation. I think what you want is an office type window that can slide open to allow words or papers to be exchanged between occupants but normally closed to provide privacy.
Because of the size limitations perhaps you will consider a swinging door made of plexiglass that would be hinged to the wall. Similar to a cloths shoot.

 

If your goal is only to move air, I don't know why you wouldn't just install a bath vent fan on one side of one wall (the room you need to vent). There must be more to this story.

 

Thanks for this useful input.
