<p>The gutter (5) comprises a third profile (13) located above a second profile (10) used for guiding rainwater. A second set of partition walls (14) extend between the second and third profiles in order to form a second bend-resistant tube (15) between these profiles. The second partition walls include rainwater discharge holes (18), which ensure that rainwater falling on the roof panes drains away onto the second profile via these holes. The greenhouse roof has at least two crests with a gutter in between. Window rods (6) mounted between each crest and the gutter are used to support the edges of window panes. The gutter comprises a first profile, a second profile located above the first profile, a first set of partition walls (11) extending between the first and second profiles to form a first bend-resistant tube, (12) a support means (16) for the undersides (17) of the window panes and a second profile for guiding rainwater.</p> |
