Benefits of Roller Shutters
An increasing number of home and business owners are discovering the numerous benefits offered by roller shutters. Though frequently used as hurricane shutters, roller shutters also offer privacy, security, reduced noise pollution and increased energy savings to those who live outside of hurricane regions.
How Roller Shutters Work
A window roller shutter is made up of three parts: a housing unit (also known as a head box), a retractable curtain/screen, and rolling guides or tracks. Roller shutters are installed over a window or door, sometimes within the wall for reduced visibility, and the tracks are mounted on the sides of the window.
Roller shutters can be opened or closed from inside your home or business either manually or automatically. Crank handles or pull straps are used for easy manual operation, or roller shutters may be controlled electronically via a wall switch or remote control.
Roller shutters are made from aluminum or PVC for the strongest protection you can find for your windows. Increased heat and noise insulation can also be achieved by using foam filled roll-up window shutters.
