This video by Technology Connections talks about how window awnings can greatly help cool your home.
Another thing I want to add is that window awnings can protect windows. We get pretty big hail here, and (wood or aluminum) awnings can save your window glass. I have also heard of “Clamshell Awnings” which are on hinges, so you can remove the poles and lower the awning to cover and protect windows in extreme weather.
Lastly, here are some old window awning ads for your entertainment (from Wikimedia commons)
is that to have someone install it for you as well, or just the awning itself? I’ve been thinking about welding up some aluminum slat awnings because the materials should be affordable for making it myself, but I have yet to research if any particular calculations are needed for the sunlight angle or anything else. Based on other home alterations I assume getting someone else to do it would be expensive.
