Storm shutters were not meant for decoration only. They were invented for a reason, and that reason was to protect expensive glass windows in storms. Back in the 1800's and even earlier, glass was a precious commodity that was very costly to ship due to its fragility. You had to have a lot of money to buy glass window panes, and you definitely did not want anything to destroy them. If they arrived to the site where you were building your new home in one piece, you counted yourself very lucky.
