As a verb, the term ‘to shutter’ is associated with pouring concrete into a form or mould so it stays in place until it hardens. This is sometimes referred to as shuttering. Shuttering is perhaps the most common type of formwork and is normally constructed on site using timber and plywood. For more information see: Formwork.
As a noun, a shutter - in the most general terms - is an object that secures an opening and restricts light from coming into a space. Typically this is a manually operated panel, cover or other type of screen that blocks a window or door. A shutter can also be a mechanical device (particularly in photography).
 Types of shutters
There are several types of shutters.
Window shutters are generally pairs of hinged panels fixed inside or outside a window that can be closed for security, or privacy. Window shutters are also designed to keep out the light and to prevent the passage of heat. Window shutters can be solid panels made from almost any material that can be fitted within a frame. They can be horizontally or vertically louvred and fashioned so they are fixed or operable.
Roller shutters are another type of window shutter that can also be used on doors or windows. These can be referred to as security shutters, coiling doors, roller doors or sectional overhead doors. These devices are made up of numerous horizontal strips that are connected with hinges. Roller shutters can be motorised or operated by hand.
See exterior shutters.
In terms of life safety, a fire shutter can be part of a fire protection system. A fire shutter is a type of roller shutter designed to restrict the spread of smoke and fire. These shutters can close automatically if a fire is detected.
