Shutter
[edit] Introduction
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.
Shuttering (as a verb) can also mean to close permanently or go out of business (as in the expression, ‘to shutter a business’).
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).
[edit] 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.
For more information, see Fire doors in buildings.
NB Short Guide, Scottish traditional shopfronts, published, on 18 April 2017 by Historic Environment Scotland, defines shutters as: ‘A security feature for the protection of goods and of valuable glass. Wooden boards were available from the mid-18th century. They were lifted in and out of the shop and placed into special grooves or slots in the windows and fixed with an iron shutter bar. Roller shutters were introduced in the early 19th century but wooden lifting shutters remained popular into the early 20th century. Metal roller shutters are now popular with shopkeepers as these may be perceived as offering a higher degree of security but can be visually intrusive, particularly for traditional shopfronts.’
