Demountable partitions, have a characteristic lightness in weight. Removal and subsequent relocation of demountable partitions do not materially affect the adjoining spaces or structures. Demountable partitions can be moved around to suit the changing user needs. In buildings for Industrial, Commercial, Health and Educational purposes changes in work processes, plants and equipments, economic, social and political relevance occur very rapidly, and demountable partition systems of walls provide the required flexibility.
Essential characteristics of demountable partition walls are: light weightiness, manageable size (transport, carriage through a stair and elevators), seamed but mating edges, forming and siting geometry, interlocking mechanisms, other fixing devices, allowable core for removal and reinstatement of services (electrical, communication), changeable surfaces, repair-ability, dimensional adjust-ability. Demountability and remount-ability enforces modularity.
Demountability: Cost, performance and appearance of a partition system are affected by the option of demountability. The complexity of the demounting and remounting the partition installation and accompanying alterations in the surroundings require careful considerations. For example regular adaptation to be handled by the user require the ease of sliding or folding mechanisms. Once in a while changes must be carried out by maintenance staff, to allow the use of a more sophisticated systems. With very easy to demount partitions, the quality of sound and thermal insulation are significantly poor. Lighting and other services in demountable systems are basic (bare minimum) only, and involve higher costs but complex detailing and pre planning.
Demountability of a partition system is a permanent removal and re-installation at the same or some other location. It could also include the fold-ability or collapse-ability to shrink the spread or effectiveness. There are basic two directions of collapse horizontal and vertical. Camera lens shutters have multiple flanges moving in radial position. Beyond the fold-ability or collapse-ability options, partitions can shift to less used space sections. Mines and warehouses use such shifting partitions to achieve 100% gap opening. Bamboo curtains of woven mats, banat or chattai in India, are flexible sheet structures that allow pushing ajar a portion of it.
