Inside window shutter, on the other side of the glass

 The inside window shutter has several advantages over the exterior shutter. The first and most noticeable is that it requires far less maintenance. Being well protected from the harsh outdoor environment, away from the freezing cold and pouring rain, it’s sure to last far longer than it would on the outside with far less maintenance requirements.

It also means that you can adjust the internal shutter without opening your windows, which might be a big advantage for people with mobility problems. On the other side, this type of shutter is not as effective as keeping your house cool as the exterior shutters. When on the outside, the shutter effectively blocks the sun, preventing excess heat from entering your home – when placed on the inside most of the heat gets in before blocked. That explains why you’re most likely to find inside window shutters in colder climates and exterior shutters in warmer ones.
