Open roof greenhouses provide a environment for plant growth when the outdoor climate would work and an artificial environment when it’s too hot or frosty. Starting the roof over the plants increases light intensity that may help to control the growth 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 level of flexible plastic-type glazing that operates the length of the greenhouse bay. A small gear engine rotates a shaft that winds the plastic 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 weather. Starting and closing the roof could 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 as they can be tightly closed during cold weather. Most designs use regular vent hardware. Some possess panels that hinge at the gutter and open up upward. Opening is almost 100%. Others have panels that are Gearbox For Greenhouse hinged at the ridge and one gutter and slide sideways on teflon bearings. Opening is approximately 85%. Most designs make use of rubber gasketing to seal the joints. Glazing could be glass, polycarbonate or film plastic material. Some manufacturers provide a movable gutter to collect rainwater when the roof is definitely partially open up. Wind sensors ought to be installed to close the roof in stormy weather. Movable shade is frequently installed with the open roof design. It reduces heat load by reflecting the suns rays back again out. The color curtain should be of a porous style to allow heat to flee. In northern climates a power blanket may also be installed to reduce heat loss through the winter.
These structures consist of a steel frame, versatile glazing and cable support. Woven UV stabilized polyethylene film produces a watertight glazing. Based on the cropping system, bracing of the framework can be external cables attached to deadmen, inner compression braces or trusses with cable X bracing. Flat roof designs are used where there is little rain or snow. A-roof styles shed the rainfall and snow to an internal 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 leading edge of the curtain. One equipment motor will deal with up to 50,000 sq ft of roof Heating is more difficult than in a conventional greenhouse because of the single layer plastic material and greater infiltration through gaps and cracks in the seals.
