Why Are Shutters Still So Beneficial to Homeowners?

Before the invention of glazing, people had to put up with holes in their homes to let light in. In Roman times, for example, the only way to stop heat escaping out of such a portal was to fit exterior shutters but this would also mean blocking out sunlight during the day. Now, homeowners can use strong windows and window treatments to protect their home from the elements.  Today, there are plenty of internal window treatments to choose from including Venetian blinds, polarising glazing, curtains and Roman blinds, to name but a few.
