Interior shades aren’t nearly as effective as exterior. Once that sun gets through the window, it’s already giving that next interior surface quite a bit of heat.

There are many styles of awning or other shading elements. You can have metal slats or what looks like a wood box that comes out horizontally over the window. I’m sure something could fit your house’s aesthetic. And perhaps ask your wife what value she’d put on thermal comfort.

Looking for shading elements or shading strategies might get broader results than simply sheet metal or fabric awnings.
