1. A roof panel for a greenhouse roof, the panel comprising:
- plural pairs of transparent roof subpanels (12, 13), said roof subpanels of each of said pairs meeting along a respective apex (16) that runs at a first non-zero angle (θ
) from horizontal when installed in a greenhouse roof, said roof subpanels sloping away from said apex at a second non-zero angle (γ
) that remains constant along a length of said apex, said apexes being parallel to each other, each of said pairs of roof subpanels meeting an adjacent one of said pairs along a respective nadir (18) that runs at the first non-zero angle from horizontal, said nadirs being parallel to said apexes, each of said roof subpanels comprising a roof sheet (71) and a base sheet (73) that are separated from each other by a first non-zero distance (h4), said roof sheet and said base sheet being parallel to each other and connected to each other with partitions (75, 76).

Abstract
Greenhouse (1) provided with a roof element (2) having a multiplicity of transverse ribs (12, 13, 14, 15) or pyramids uniformly distributed over the roof element. The roof element can be constructed double-walled as a hollow-core sheet from transparent plastic and can comprise a base sheet with the rib-shaped or pyramid-shaped roof surfaces fixed thereon. The light yield in a horticultural greenhouse can be increased by the roof elements.

10. A greenhouse roof with a longitudinal direction (L) and a transverse direction (D) perpendicular thereto, the roof comprising:
-
plural pairs of transparent roof surfaces (5, 6, 7, 8) in succession in the transverse direction, the roof surfaces of each pair of the plural pairs of roof surfaces meeting adjacent to a respective first apex (9, 10), each of the roof surfaces extending from adjacent to a respective base edge (11) at a first non-zero angle (θ
) from a horizontal extending in the transverse direction, each said first apex and each said base edge extending in the longitudinal direction; and
each of the roof surfaces comprising plural pairs of roof subpanels (12, 13) in succession in the longitudinal direction, the roof subpanels of each pair of the plural pairs of roof subpanels meeting along a respective second apex (16) that runs at the first angle from the horizontal and extends from adjacent to a respective said base edge to a respective said first apex, each of the roof subpanels lying at a second non-zero angle (γ
) relative to a horizontal extending in the longitudinal direction, wherein said roof subpanels of one said roof surface meet said roof subpanels of an adjoining said roof surface adjacent to said first apex along two edges that slope away from said first apex at the second angle (γ
) relative to the horizontal wherein said roof surfaces are double-walled. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25)
