<p>Warm air is conducted in a device mounted above heating bodies, esp. radiators, in a room. It is made up from a separately prefabricated form body, which is an air-ducting bracket assembly, incorporating one or more surfaces functioning as air- ducting surface; there is pref. only one of these (1). It can be in the form of a screen-type unit with supports or other fixture connections at right angles to it, enclosing it at approx. right angles (3). It can be adjoined by a rear connecting surface (2). Such provision is more convenient and more easily mounted than ducting surfaces made individually by plastering.</p> |
