Tip before getting these windows installed be sure to measure the amount of outside clearance the window will have.
Build your own window awning.
Purchase 1 inch wide by 6 inches long 2 54 cm wide by 15 24 cm long boards to create the awning frame.
Create a 2 dimensional square frame and attach an equally sized square frame to it so they share a middle spine.
I wanted to be able to still see out of the window so if you do too test the angle with someone inside.
Make 2 identical 2 dimensional right triangle frames attached to the ends of your square frame.
I picked the about 45 degrees.
Choose a length of pvc and elbow so that the awning hangs at a desired angle.
