An apparatus for regulating the radiation of light and/or heat by the use of slats which are suitable for placing under a roof constructions, such as a greenhouse roof, in which the slats 140 are supported at or adjacent each end by a pair of laterally spaced apart connecting cords 136,137. These cords form the sole suspension for the slats and are mounted, at their upper ends, on a combined tilting and carrier means 102,107,108,115. Drive 128 is provided for the combined carrier and tilting means so that the latter impart a movement from which the tilting movement of the suspended slats is directly derived. It is also possible for the slats to be drawn back by movement of runners 134,135 on the combined carrier and tilting means.

Apparatus for regulating the radiation of light and/or heat with the aid of slats, suitable for placing under a roof construction, for example, under a translucent roof as is used in greenhouses, said apparatus comprising, in combination: (a) a plurality of elongate, substantially parallel, slats spaced transversely from one another; (b) at least two carrier means mounted above said slats and extending transversely with respect thereto; (c) at least one of said carrier means being in the form of a combined carrier and tilting means; (d) a plurality of pairs of connecting members at the location of said carrier means, whereby each slat is solely connected to the associated carrier means and individually suspended therefrom by means of pairs of connecting members and, at the location of said combined carrier and tilting means, the connecting members of each pair are attached to the slats at two points spaced apart transversely to the length of the slats; and (e) drive means for said at least one combined carrier and tilting means effective to impart a movement thereto from which a slat tilting movement of said slats is directly derived.
