Nope, they look like casement windows on their side with the hinge on top....
we stacked one set as we got a really good deal from Honsador - they had a return on a custom order of 2 windows that were as wide as we needed, but just under 1/2 the height...and we decided to stack the two... that is by far the best window arrangement of all...luckily this is in the kitchen area, so having the best window arrangement there is doubly best...They were Coastal & here is the link that inspired the stacking:

The smaller jalousie windows are fine enough, but they do not seal well at all and they do not have as clear a view...not a really big deal for all to most all of the time in Keaau town - but those 2 days of wildfires in the area would have smoked up our house (2 out of 2850 - not soo bad!)
Casement & slider windows have one HUGE drawback, even with a good overhang, there are those times that the winds might carry rain into your house.... to keep rain out, you will need wrap around lanais....which has even more positives, as most of the time, that is THE place to be!
ADDED SOLAR - a lot of people here know about solar - & there have been many previous posts - you may just want to click on the search button & search on solar - there is enough reading there to keep one out of trouble.....
It is not that we lack the knowledge for our system... I just want something that is here, but no one seems to know how it got here & how I can get the same system installer here....
My dream solar & lanai (all of which is engineered & qualifies for tax credits...and now uses a newer holographic panel):
