Open roof greenhouses provide a environment for plant growth when the outdoor weather conditions would work and an artificial environment when it is too hot or chilly. Opening the roof over the plants increases light intensity which can help to control the growth habit, flowering and crop timing. It also reduces electrical power costs as expensive fan cooling is not needed.
Several methods are used to open the roof. Some manufacturers make a roof that opens by rolling up the single or double coating of flexible plastic glazing that operates the distance of the greenhouse bay. A small gear motor rotates a shaft that winds the plastic-type on to it just like a window shade. A light, second framework over the Gear Motor For Greenhouse structure secures the plastic-type from bellowing out during windy climate. Opening and closing the roof can be either manual or automatic. Each side of the roof could be managed independently for flexibility in cooling.
Folding roof greenhouses work very 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 upward. Opening is almost 100%. Others have 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 could be cup, polycarbonate or film plastic-type material. Some manufacturers give a movable gutter to gather rainwater when the roof is partially open. Wind sensors should be set up to close the roof in stormy climate. Movable shade is frequently installed with the open roof design. It reduces 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 can also be installed to lessen heat loss through the winter.
These structures contain a steel frame, versatile glazing and cable support. Woven UV stabilized polyethylene film creates a watertight glazing. Depending 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 styles are utilized where there is little rainfall or snow. A-roof styles shed the rain and snow to an interior gutter system. Styles 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 shifting the industry leading of the curtain. One equipment motor will deal with up to 50,000 sq ft of roof Heating system is more challenging than in a conventional greenhouse due to the single layer plastic-type and greater infiltration through gaps and cracks in the seals.
