Open roof greenhouses give a environment for plant growth when the outdoor climate is suitable and an artificial environment when it is too hot or chilly. Starting the roof over the vegetation increases light intensity that may help to control the development habit, flowering and crop timing. In addition, it reduces electrical power costs as expensive fan 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 layer of flexible plastic glazing that operates the space of the greenhouse bay. A little gear engine rotates a shaft that winds the plastic-type on to it like a window color. A light, second framework over the framework secures the plastic-type from bellowing out during windy weather. Starting and closing the roof can be either manual or automatic. Each aspect of the roof can be controlled independently for flexibility in cooling.
Folding roof greenhouses work well in snowy climates because they can be tightly shut during cold weather. Most designs use standard vent hardware. Some have panels that hinge at the gutter and open up upward. Opening is nearly 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 make use of rubber gasketing to seal the joints. Glazing can be glass, polycarbonate or film plastic material. Some manufacturers provide a movable gutter to gather rainwater when the roof is partially open. Wind sensors should be installed to close the roof in stormy climate. Movable shade is generally installed with the open up roof design. It reduces heat load by reflecting the suns rays back again out. The color curtain should be of a porous design to allow heat to flee. In northern climates an Gearbox For Greenhouse energy blanket can 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. With respect to the cropping system, bracing of the structure can be external cables mounted on deadmen, internal compression braces or trusses with cable X bracing. Flat roof styles are utilized where there is little rain or snow. A-roof styles shed the rain and snow to an internal gutter system. Designs that may carry up to 35 lb/sq ft snow load and 100 mph wind loads can be found. The roof opens in sections by moving the industry leading of the curtain. One gear motor will deal with up to 50,000 sq ft of roof Heating is more difficult than in a conventional greenhouse due to the single layer plastic material and higher infiltration through gaps and cracks in the seals.
