Abstract (en)
[origin: WO2015167338A1] A roof structure for a greenhouse or warehouse comprising mutually parallel gutters (1) extending in a longitudinal direction and a raised cover (2) extending between the gutters. The cover comprises a support structure (3, 5) supported on the gutters, an outermost translucent cover layer (15) as well as an innermost translucent cover layer (7) which together delimit a cavity (8) and which are supported by the load-bearing structure (3, 5). The roof structure is provided with a ventilation duct (12) that extends along the cavity (8) and that is connected by at least one opening (11) to the interior of the cavity, wherein the ventilation duct is adapted for exchanging a gas as ventilation medium between the ventilation duct and the cavity through at least one opening, for ventilating the internal space of the cavity. At least one of the gutters (1) comprises a tubular shape which defines the ventilation duct (12).
