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 frosty. Opening the roof over the plant life increases light intensity which can help to control the growth habit, flowering and crop timing. It also reduces electricity costs as expensive fan cooling isn’t needed.
Several methods are used to open the roof. Some manufacturers make a roof that opens by rolling up the solitary or double coating of flexible plastic glazing that runs the distance of the greenhouse bay. A small gear electric motor rotates a shaft that winds the plastic on to it like a window color. A light, second framework over the framework secures the plastic-type material from bellowing out during windy weather. Opening and closing the roof can be either manual or automatic. Each 
aspect of the roof can be controlled independently for versatility in cooling.
Folding roof greenhouses work well in snowy climates as they can be tightly shut during winter. Most Gearbox For Greenhouse designs use regular vent hardware. Some possess 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 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 can be partially open up. 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 heat load by reflecting the suns rays back again out. The color curtain ought to be of a porous design to allow heat to escape. In northern climates a power blanket can also be installed to reduce heat loss through the winter.
These structures consist of a steel frame, flexible glazing and cable support. Woven UV stabilized polyethylene film produces a watertight glazing. Based on the cropping program, bracing of the structure could be external cables attached to deadmen, inner compression braces or trusses with cable X bracing. Flat roof styles are utilized where there is small rainfall or snow. A-roof designs shed the rainfall and snow to an internal gutter system. Designs 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 gear motor will handle up to 50,000 sq ft of roof Heating is more challenging than in a typical greenhouse due to the single layer plastic and better infiltration through gaps and cracks in the seals.
