Remodel Aholic shares a picture filled tutorial of how to build interior shutters for your home, garage or garden shed.
Shutters may be employed for a variety of reasons, including controlling the amount of sunlight that enters a room, to provide privacy, security, to protect against weather or unwanted intrusion or damage and to enhance the aesthetics of a building as quoted on wikipedia.
In parts of the country there are powerful ind storms that come up suddenly, interior shutters can create a barrier in case an object such as a tree branch breaks through a window glass pane.
By painting the side of the shutter that is exposed to the sun black, it will absorb heat while acting as a second layer of protection from cold winter weather.
