The terms accordion shutter is frequently used to describe a interior shutter unit that uses panels that hinge together. An accordion interior shutter unit would attach two or more panels together so they open in the same direction. The outside panel would hinge to the window jamb or to a hang strip directly outside the window opening. When fully open, the shutters all stack (front to back) to create maximum visibility through the opening. A bi-fold shutter unit would only attach two shutter panels so they would fold in the same direction.
Accordion
shutters is not the best
phrases to use when describing a folding shutter unit. Instead,
refer to the number of shutter panels across and how many panels
hinge and open to the left side and how many open to the right.
An accordion bi-fold shutter unit with four panels across usually
open two panels to the left and two to the right. An accordion shutter unit with six panels across usually open three
panels to the left and three to the right. It is possible to
hinge all panels together and open them to one side.
Accordion doors or doors are often used to cover interior closets and pantrys. The accordion doors open to the side of the opening allowing entry to the contents.
Shutter Tip:
Some local shutter companies that measure and exterior shutters will tell you that they are "certified installers" to discourage you from attempting to measure for and install shutters yourself. Most likely they certified themselves or attended a one day training session with their supplier. With proper instruction, homeowners are fully capable of measuring and installing shutters themselves.
A different type of sliding exterior accordion shutter is used for hurricane and storm protection. This type of shutter is only used in inclement weather and security on outside windows.
