These greenhouses models are named Tropical greenhouses because their use is widespread in this region, and also asymmetric, because, unlike the Gothic and chapel greenhouses, its geometry is asymmetric, with one side of the roof steeper than the other.
The slope of the roof is studied as a function of perpendicular incidence on this of sunlight during the winter, in order to maximize the incoming solar radiation
Novedades Agrícolas manufactures this greenhouse under its own brand APR, naming this model as APA25, APA40 y APA40H.
The greenhouse ventilation is usually fixed and is determined through the openings located in the center of each structural arches which run along the entire ceiling. The openings allow natural ventilation and heating vent.
Advantages:
-Make possible utilize the light in winter
-High thermal inertia due to their high unit volume
-Waterproof to rain and air.
-BGood ventilation due to its high altitude.
-Allows installation of roof ventilation downwind.
-Strong winds resistance.
-It is fast to assemble and needs no welding.
Standard Features:
The standard dimensions of this type of greenhouse are:
-Width: 9.60 m.
-Pillar height: 6,4 - 6,90 - 7,40 m.
-Height on canal: 4 - 4,50 - 5 m.
-Distance between pillars: 4 - 5 m. (inside). 2 – 2,50 m. (outside).
-Racks perimeter reinforcement.
When is your right choice?
It is designed for the development of all crops in tropical climate with warm temperatures and high humidity. Provides effective roof ventilation, usually fixed. The zenith windows are intended to protect the crop from strong winds typical of tropical regions.
