I have a totally stupid question. How do real working shutters work, particularly when combined with modern windows? This has been something that I've always wondered but never chosen to figure out. Particularly when I have a similar reaction to yours. "Those shutters don't do anything, what's the point." But then I realize I don't know how actual working shutters function. And then I forget about it.
In terms of their purpose? When used properly, you open the window and close the shutters (no bug screens). This allows a breeze to pass through and blocks out direct sunlight. They're still used this way in Mediterranean countries and similar climates. You typically only turn on the A/C in the hottest hours of the afternoon, usually one of those Mitsubishi mini-split systems. The other biggest advantage is that shutters block heat and sunlight from the outside. Blinds do very little to prevent heat from entering a building. Once sunlight has passed through a window, it's in the building for good.
