Open roof greenhouses provide a environment for plant growth when the outdoor weather would work and an artificial environment when it is too hot or cool. Starting the roof over the plant life increases light intensity which can help control the growth habit, flowering and crop timing. In addition, it reduces electricity costs as expensive fan cooling is not needed.
Several methods are used to open up the roof. Some producers make a roof that opens by rolling up the single or double layer of flexible plastic material glazing that operates the distance of the greenhouse bay. A small gear motor rotates a shaft that winds the plastic-type material on to it like a window shade. A light, second framework over the framework secures the plastic material from bellowing out during windy weather conditions. Starting and closing the roof could be either manual or automatic. Each aspect 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 shut during winter. Most designs use standard 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 approximately 85%. Most designs use rubber gasketing to seal the joints. Glazing can be glass, polycarbonate or film plastic-type material. Some manufacturers provide a movable gutter to gather rainwater when the roof is certainly partially open. Wind sensors should be set up 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 again out. The shade curtain ought to be of a porous design to allow heat to flee. In northern
climates a power 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. According to the cropping system, bracing of the structure could 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 rain and snow to an interior gutter system. Designs that may carry up to 35 lb/sq ft snow load and 100 mph wind loads are available. The roof opens in sections by moving the industry leading 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 due to the single layer plastic material and better infiltration through gaps and cracks in the seals.
