I always wondered about the practicality of outdoor window shutters, which were a staple on old houses, even back in the Midwest.
Now that I’m living along a coast that for months has had small-craft or gale warnings in our forecasts seemingly daily, the appendages make a lot more sense. They’re not just decorative. Objects blow about like projectiles, for sure, but more than that, a layer that breaks the icy wind before it slams up against the glass panes and worms through the sash into the house definitely adds some relief.
Of course, our Cape has only one remaining shutter, and it’s too small for the window beside it. Purely decorative, it’s nailed securely to the siding. Hopefully, it provides some extra insulation there.
