Open roof greenhouses provide a natural environment for plant growth when the outdoor climate is suitable and an artificial environment when it’s too hot or cold. Starting the roof over the vegetation increases light intensity which can help control the development habit, flowering and crop timing. It also reduces electrical power costs as expensive lover cooling isn’t needed.
Several methods are used to open up the roof. Some producers make a roof that opens by rolling up the solitary or double layer of flexible plastic-type glazing that operates the distance of the greenhouse bay. A little gear motor rotates a shaft that winds the plastic material 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. Opening and closing the roof could be either manual or automatic. Each side of the roof can be controlled independently for flexibility in cooling.
Folding roof greenhouses work well in snowy climates as they can be tightly shut during cold weather. Most designs use regular vent hardware. Some possess panels that hinge at the Gearbox For Greenhouse gutter and open 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 use rubber gasketing to seal the joints. Glazing could be cup, polycarbonate or film plastic. Some manufacturers provide a movable gutter to gather rainwater when the roof is certainly partially open up. Wind sensors ought to be set up to close the roof in stormy weather. Movable shade is generally installed with the open roof design. It decreases the heat load by reflecting the suns rays back again out. The shade curtain should be of a porous design to allow heat to flee. In northern climates an energy blanket can also be installed to reduce heat loss through the winter.
These structures contain a steel frame, versatile glazing and cable support. Woven UV stabilized polyethylene film produces a watertight glazing. Based on the cropping program, bracing of the framework could be external cables mounted on deadmen, internal compression braces or trusses with cable X bracing. Flat roof designs are utilized where there is small rainfall or snow. A-roof styles shed the rain and snow to an internal gutter system. Styles 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 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 typical greenhouse due to the single layer plastic material and higher infiltration through gaps and cracks in the seals.
