Abstract
To avoid or at least substantially reduce heat losses occurring with conventional registers ventilation, a register is disclosed which is assembled of two basic bodies supporting each a shutter and connected to each other through a thermally insulating layer. Preferably, the thermally insulating layer comprises insulating sectional strips and it is satisfactory to provide such strips only along the upper and lower longitudinal edges of the two basic bodies. The two shutters are coupled to each other so that they can be shifted conjointly from their closing to their open position and vice versa by means of a single drive mechanism.
