Naturally Ventilated Greenhouse

Naturally Ventilated Greenhouse are framed structures covered with transparent or translucent material large enough to grow crops under partial or fully controlled environmental conditions to get optimum growth and productivity. There are several types of Greenhouses i.e. Naturally Ventilated Greenhouse, Saw Tooth Standard Greenhouse, Multi Span Umbrella vent Greenhouse, Commercial Naturally Ventilated Green House.

We, Ethics Infinity Pvt. Ltd. are engaged in fabrication and construction of Naturally Ventilated Greenhouse. The Naturally ventilated Greenhouse is designed to meet the growing needs of farmers around the world to produce higher quality crops thus enhance the return. This Naturally Ventilated Greenhouse is designed to solve the problem of ventilation and humidity and is especially suited for hot and humid weather conditions.

Our Naturally Ventilated Greenhouse having vents at Top and Sides. It transfers air arising as the density difference between hot and cold air through air vents. Air exchange rates are very low and much dependent on the temperature difference between internal and ambient air. These greenhouses mainly rely on the wind pressure generated from one side and released from another side. In Naturally Ventilated Greenhouse, The Open Top Roof vents allows continues air flow to rescue the inside temperature to maintain the optimum level. The Open roof has wide anti-rain overlap, Protecting Crop from inflow of Rain. The Open Roof can also be made fully insect proof by fixing an additional screen of insect Netting.

We provide fully hot Dip galvanized structure covered with 200 micron polyethylene film. All our components are prefabricated and there is no welding at site. We provide Hot Dip galvanized Industrial Press Gutter and Hot Dip galvanized plate clamps which ensures long life of Structure. Structure design is designed technically such that it can withstand against the wind load of 150 Km/hour.

Different Types Of Design

Major Design Considerations

Roof vent opening should be 10-15% of floor area and open leeward to wind

Windward side vent opening should equal one fourth all the roof vent openings

Side vent should be prevented from going directly out the first top vent

The windward side should be highly aerodynamic

A 50% shading system is very important for summer growing

Internal profiles should curve smoothly upward and out the vents (no traps)

Computer control is highly desirable for climate control and vent protection
