Why isn't this common?
Looking at the picture in previous item, I was struck by a random neuron firing.
Why aren't more houses equipped with
short and solid awnings like this?
It wouldn't be needed on this particular bungalow with a nice wide roof overhang, but it would be helpful on Cods or newer ranchy types.
The usual aluminum awning does a good job of sunshielding, but it also collapses under snowload and blows off in a windstorm.
This mini-awning would be a compromise. It would protect the window from
most rain, and would block the worst of noontime sun without blocking low winter sun. It wouldn't hold snow or catch wind. If it's built as a solid or hollow piece of fiberglass, it wouldn't encourage wasps.
Later: Tried a web search. Figured the item itself was commonly available but not commonly used. Nope, it's not common at all.
This small copper visor is about as close as I can find. It's the right size but it's not solid and 'streamlined'. Wind could grab it, wasps would love it.
