Open roof greenhouses provide a environment for plant growth when the outdoor weather conditions would work and an artificial environment when it’s too hot or cold. Opening the roof over the vegetation increases light intensity which can 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 coating of flexible plastic glazing that runs the space of the greenhouse bay. A small gear engine rotates a shaft that winds the plastic-type material on to it such as a window shade. A light, second framework over the structure secures the plastic-type from bellowing out during windy weather. Starting and closing the roof can be either manual or automatic. Each part of the roof can be controlled independently for versatility in cooling.
Folding roof greenhouses work very well in snowy climates because they can be tightly closed during cold weather. Most designs use standard vent hardware. Some have panels that hinge at the gutter and open upward. Opening is nearly 100%. Others possess 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. Some manufacturers provide a movable gutter to collect rainwater when the roof is certainly partially open. Wind sensors should be set up to close the roof in stormy weather. Movable shade is frequently installed with the open up roof design. It reduces the heat load by reflecting the suns rays back out. The shade curtain should 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 Gear Motor For Greenhouse structures contain a steel frame, flexible glazing and cable support. Woven UV stabilized polyethylene film produces a watertight glazing. Depending on the cropping program, bracing of the framework can be external cables attached to deadmen, internal compression braces or trusses with cable X bracing. Flat roof designs are used where there is little rainfall or snow. A-roof designs shed the rainfall and snow to an interior gutter system. Styles 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 industry leading of the curtain. One equipment motor will deal with up to 50,000 sq ft of roof Heating is more challenging than in a typical greenhouse because of the single layer plastic and higher infiltration through gaps and cracks in the seals.
