ININSA - Model P-9’60 - Gothic Roof Multi-Span
The P-9’60 greenhouse model, which is called “Gothic model”, differs from P-8 model (Curved roof multi-span) in the way that the first one has wider bays (9’60m); its roof is slightly pointed in the highest point; its ridge pole height is greater; and it is possible to fit it out simple or double zenithal ventilation. - See more at: http://www.fabricanteinvernaderos.com/english/products/greenhouses/gothic-roof-multi-span/#sthash.82KNwLqI.dpuf
At the same time, the Gothic model has more volume of air inside than the curved roof model, because of the height difference from drain gutter to ridge.
The P-9’60 Gothic model measures 2’70m and the P-9 curved roof model measures 1’80m. We offer two types of zenithal ventilation for the Gothic model: “Super-zenith” and “Super-zenith Plus”. Both types are able to be installed simple or double even the possibility of alternating both in the same greenhouse.
