Looking for advice on using different types of windows as we renovate our house.

We currently have a mix of fixed (picture or inoperable), single hung and awning windows, as well as sliding glass doors. I don't dislike the current look overall, but in some rooms the windows aren't as functional as we would like.

Our next reno project involves a large rec room type space where there are 2 sets of sliding glass doors and a number of fixed windows. We are looking to replace 2 fixed windows which are ~30" wide with operable ones. The windows are not side by side, nor can we make the openings wider as both are between side walls and patio doors. Moving the patio doors is not in the plan - there are not enough advantages to justify the costs. The ceilings in this room are just under 8' (it's a basement of sorts) so the windows can not be very tall. We will have a 36" counter below one of them so after adding in space above the 36" counter for window sill and apron, the window can only be ~36" tall. (We want to keep the existing window headers so raising the top of the window is not an option.)

I was originally thinking of double hung windows to stay with the horizontal lines of the single hung and awning windows we have elsewhere, however dividing a 30"W x 36"H space horizontally is going to result in a fairly squat looking window in a room with low'ish ceilings. Sort of like a not very tall person (me) wearing horizontal stripes - just don't! ;) This has lead me to consider using horizontal sliders in this room. This would get away from the 'squat' looking horizontally divided shape, take your eye upward in a room with low'ish ceilings, and stay with the vertically divided look that the 2 sliding glass doors bring into this room. Also, the outside of this area is beneath a deck of the upper floor, so we can see the upper deck posts from these windows - more vertical lines. In this area of the house, both from inside and out, you do not see any other windows.

So, what are peoples' thoughts on this idea? Am I crazy to mix sliders (vertically divided) on this elevation with single hung and awing (horizontally divided) windows elsewhere even though you can't see them at the same time? If this is an idea I'll regret, I'd appreciate your suggestions on what to do!

Note: I did consider casements so the whole 30" x 36" shape is undivided, but these windows both open onto a deck and casements will be in the way outside when open. Also, we live in an area where screens are a must and I dislike the screens being on the interior as I then have to remove the screens to vacuum the debris from the screens' exterior more often than I would like. When the screens are on the outside I can simply brush the screens off with a broom when I sweep the deck.

Thanks for your input!
