When it comes to letting the outdoors in, casement windows can be a great option. When a casement is open, 100% of the window area is open instead of 50% as with double-hung windows. It's a terrific window to use in the kitchen for those who want to be able to really open things up this time of year.
The window pictured up top is from Cote de Texas' own kitchen renovation, where a casement window replaced the existing metal-framed window.
Cote de Texas' window doesn't appear to have a screen, which makes it beautiful and so very open. But if you do determine that a screen is necessary, that adds another layer of consideration. Window screens are located on the interior of casement windows, so that can effect their use in the kitchen. Be sure the window is in a spot where you would be able to keep the screen clean and not in a spot where the screen would catch a lot of cooking particles.

I love this idea! With a casement window like this, perhaps I could entice with seed the little finches, sparrows and robins that frequent the tree directly outside my kitchen window, and I could enjoy their colors up close!
I think casement windows demand retractable screens--makes way more sense.
The fact that my 50s era house had all new windows was a real selling point--the fact that they are casement is a nice bonus! I love cranking them out.
That area in the photo is gorgeous. That sink is like a little bathtub!
I am drooling over the sink and countertop! Lovely.
My childhood home had casements at all the windows. But ours opened in which meant that screens/storm windows were perfectly normal ones.
I loved those windows.
what would be even better if there were no divider down the window in the photo above... But I supposed I'm spoiled living in Germany where all the windows in my apartment are casement windows without any frame in the middle. Glorious to open both sides at the same time and let the outside flow in.
Am I missing something? That just looks like an ordinary window to me, so I'm not sure what it's being contrasted with. The only other kind I'm familiar with are sash windows, but you really only see them on houses from a certain era that haven't been re-done...
@zeropixelcount "but you really only see them on houses from a certain era that haven't been re-done..." That's an awful lot of America! Almost every window that opens in NYC for instance....
We have a casement window in the new kitchen. Love it! The only problem is: I can't reach the latch for the lock due to the added distance of reaching over the counters. I've used various cooking utensils to remedy my reach.
@ARobin: Really? Wow. Over here, I've noticed them (sash windows, that is) on poorly-maintained Victorian/Edwardian rental properties, and that's about it. Usually they don't open at all because some idiot's painted over the edges - they're invariably wooden-framed and single-glazed as well.
But hey, I've learnt a new fact, so all's good. ("Casement" previously meant 'that guy who was executed' and 'old-fashioned synonym for window')
