Open roof greenhouses give a natural environment for plant growth when the outdoor weather would work and an artificial environment when it’s too hot or cold. Opening the roof over the plants increases light intensity that may help control the development habit, flowering and crop timing. In addition, it reduces electrical power costs as expensive lover cooling isn’t needed.
Several methods are accustomed to open the roof. Some producers make a roof that opens by rolling up the solitary or double level of flexible plastic-type glazing that operates the space of the greenhouse bay. A small gear engine rotates a shaft that winds the plastic on to it like a window color. A light, second framework over the framework secures the plastic from bellowing out during windy weather conditions. Starting and closing the roof could be either manual or automatic. Each side of the roof could be managed independently for versatility in cooling.
Folding roof greenhouses work very well in snowy climates as they can be tightly closed during cold weather. Most designs use standard vent hardware. Some have 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 about 85%. Most designs make use of rubber Gearbox For Greenhouse gasketing to seal the joints. Glazing could be cup, polycarbonate or film plastic-type material. Some manufacturers give a movable gutter to collect 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 the heat load by reflecting the suns rays back out. The color curtain ought to be of a porous design to allow heat to escape. In northern climates an energy blanket may also be installed to lessen heat loss through the winter.
These structures contain a steel frame, flexible glazing and cable support. Woven UV stabilized polyethylene film creates a watertight glazing. Depending on the cropping system, bracing of the structure could be external cables mounted on deadmen, inner compression braces or trusses with cable X bracing. Flat roof designs are utilized where there is small rainfall or snow. A-roof designs shed the rain and snow to an interior gutter system. Designs which will 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 leading edge of the curtain. One equipment motor will handle up to 50,000 sq ft of roof Heating is more challenging than in a conventional greenhouse due to the single layer plastic and greater infiltration through gaps and cracks in the seals.
