From their humble, practical origins, exterior shutters have become the most popular option for outdoor window treatments. These multipurpose panels beautify, secure and increase the value of every home.

There was a time in the history of architecture when window glass was a rare and costly article. People needed to protect themselves and their homes from weather extremes, enhance their privacy and keep out unwanted intruders both animal and human. Because windows were often without glass, shuttering the windows was a logical solution to these problems.

At first people experimented with all sorts of materials for covering their windows. Among the ancient Greeks the affluent used louvered marble while the poorer folk used reeds. As time progressed wood became the favored construction material for shuttering windows. Wood has the advantage of being a renewable resource that is easy to work and versatile as well. The attributes of wood have ensured its popularity to the present day.

Modern exterior shutters encompass both the practical utilitarian units and the solely decorative nonfunctional sort. In addition to traditional wooden panels, manmade materials have entered the scene and composite woods, fiberglass, PVC and metals are featured materials in modern manufacturing.

Although only some types of wood such as teak, cedar and cypress are naturally water-repellent, modern chemistry has produced finishes that protect wood from water, weather and insect damage. This has helped wood maintain its popularity as the material of choice for shuttering windows.

Traditionally, the form of window coverings reflected the area in which they were used. Sturdy board and batten types were more often seen in areas of heavy storms and cold weather such as the New England coastline. Plantation types of the subtropical Deep South were louvered to facilitate the ventilation and control of light into the rooms that used them. Bermuda types are hung with hinges at the top. They are propped open to let in air and light while at the same time shading the window below. They can be easily and quickly be shut tight in case of a hurricane.

Typically, shuttered windows have a pair of panels that are hung on either side of the window and held open with special hardware. When they are closed they meet flush in the center and have appropriate hardware for securing them in the closed position.

Many homeowners want their home to fit a particular historical architectural style. In some cases they are required to conform to certain standards because the home is in a historic district. Because of this need, manufacturers have recreated exact replicas of authentic styles and hardware from different periods. These replicas are even available in manmade materials and as purely decorative, nonfunctional units. Some of these decorative units have all of the correct hardware, are mounted in an open position and look as though they could be closed at any moment.

The proper use of exterior shutters can accent a home the way the right picture frame can augment and reinforce the beauty of a particular work of art. If the units are to be painted there is no limit to the palette. If natural wood is used, in addition to paint a vast array of stains and finishes are available to give a natural look to the project. These units are permanent additions to the home and increase its value. The style of the panels can range from a rustic board pattern to an elegant louvered design. These can be obtained in pre-made or custom-made panels.
