Open roof greenhouses give a natural environment for plant growth when the outdoor climate is suitable and an artificial environment when it’s too hot or cold. Opening the roof over the plants increases light intensity that may help to control the growth habit, flowering and crop timing. It also reduces electricity costs as expensive lover cooling is not needed.
Several methods are accustomed to open the roof. Some producers make a roof that opens by rolling up the solitary or double Gear Motor For Greenhouse coating of flexible plastic material glazing that operates the space of the greenhouse bay. A small gear engine rotates a shaft that winds the plastic-type material on to it just like a window shade. A light, second framework over the structure secures the plastic-type material from bellowing out during windy climate. Starting and closing the roof can be either manual or automatic. Each part 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 possess panels that hinge at the gutter and open up upward. Opening is almost 100%. Others possess panels that are hinged at the ridge and one gutter and slide sideways on teflon bearings. Opening is approximately 85%. Most designs use rubber gasketing to seal the joints. Glazing can 
be glass, polycarbonate or film plastic material. Some manufacturers give 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 frequently installed with the open up roof design. It decreases the heat load by reflecting the suns rays back out. The color curtain ought to be of a porous style to allow heat to flee. In northern climates a power blanket can also be installed to lessen heat loss during the winter.
These structures contain a steel frame, flexible glazing and cable support. Woven UV stabilized polyethylene film creates a watertight glazing. Based on the cropping program, bracing of the framework could be external cables mounted on deadmen, internal compression braces or trusses with cable X bracing. Flat roof designs are used where there is small rainfall or snow. A-roof styles shed the rain and snow to an interior gutter system. Styles which 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 system is more difficult than in a conventional greenhouse because of the single layer plastic material and better infiltration through gaps and cracks in the seals.
