Open roof greenhouses provide a environment for plant growth when the outdoor weather conditions is suitable and an artificial environment when it is too hot or cool. Starting the roof over the plant life increases light intensity which can help control the growth habit, flowering and crop timing. It also reduces electrical power costs as expensive lover cooling isn’t needed.
Several methods are accustomed to open up the roof. Some manufacturers make a roof that opens by rolling up the one or double level of flexible plastic-type material glazing that runs the length of the greenhouse bay. A little gear electric motor rotates a shaft that winds the plastic material on to it like a window shade. A light, second framework over the structure secures the plastic-type from bellowing out during windy weather. Opening and closing the roof can be either manual or automatic. Each part of the roof could be managed independently for flexibility in cooling.
Folding roof greenhouses work well in snowy climates because they can be tightly closed during cold weather. Most designs use regular vent hardware. Some have panels that hinge at the gutter and open upward. Opening is almost 100%. Others have panels that are hinged at the ridge and one gutter and slide sideways on teflon bearings. Opening is about 85%. Most designs use rubber gasketing to seal the joints. Glazing could be cup, polycarbonate or film plastic-type material. Some manufacturers give a movable gutter to gather rainwater when the roof is certainly partially open. Wind sensors should be installed to close the roof in stormy weather. Movable shade is generally installed with the open up roof design. It decreases the heat load by reflecting the suns rays back out. The shade curtain should be of a porous design to allow heat to escape. In northern climates an energy blanket may also be installed to lessen heat loss during the winter.
These structures contain a steel frame, versatile glazing and cable support. Woven UV stabilized polyethylene film creates a watertight glazing. Based on the cropping program, Gear Motor For Greenhouse bracing of the structure could be external cables attached to deadmen, inner compression braces or trusses with cable X bracing. Flat roof designs are utilized where there is little rain or snow. A-roof designs shed the rain and snow to an internal gutter system. Styles that will carry up to 35 lb/sq ft snow load and 100 mph wind loads are available. The roof opens in sections by shifting the industry leading of the curtain. One equipment motor will handle up to 50,000 sq ft of roof Heating is more difficult than in a typical greenhouse because of the single layer plastic and greater infiltration through gaps and cracks in the seals.
