ROLLER SHUTTER Meaning and
Definition
-
Roller shutter is a type of window or door covering that is designed to provide security, privacy, and insulation. It consists of a series of horizontally arranged slats or bars made of metal or other durable materials, which are connected by hinges or links. These slats are mounted onto a track or guide, allowing them to roll up or down when operated.
When the roller shutter is in the closed position, the slats interlock tightly together, forming a solid barrier that prevents unauthorized access and protects against break-ins or vandalism. This makes roller shutters commonly used in commercial and industrial buildings, shops, warehouses, and garages. They are also popular for residential properties, offering added security and protection against weather elements.
Roller shutters can be manually operated using a crank handle or pull strap, or they can be motorized for convenient remote control operation. The motorized versions often feature sensors or timers for automatic opening and closing, adding convenience and ensuring the shutters are not accidentally left open.
Aside from security, roller shutters provide insulation by reducing heat loss in the winter and blocking out excessive sunlight and heat in the summer. This contributes to energy efficiency and cost savings. Additionally, roller shutters offer privacy by blocking the view from the outside while still allowing light to filter through the slats when desired.
In summary, a roller shutter is a versatile and practical window or door covering that provides security, insulation, and privacy.
Etymology of ROLLER SHUTTER
The word "roller shutter" derives from the combination of two separate words: "roller" and "shutter".
The term "roller" is derived from the Middle English word "rollere", which comes from the Old French word "roleur". This Old French word is a derivative of the verb "rouler", meaning "to roll". In this context, the term "roller" refers to a cylindrical device that rotates or moves by rolling.
On the other hand, the term "shutter" comes from the Middle English word "shuteren", which is derived from the Old English word "scyttan" or "sceotan", meaning "to shut". "Shutter" refers to a movable cover or a barrier that can be opened or closed.
Hence, when combined, "roller shutter" refers to a type of barrier or door that involves a roll-up mechanism using cylindrical rollers.
