Open roof greenhouses provide a natural environment for plant growth when the outdoor weather conditions is suitable and an artificial environment when it’s too hot or frosty. Starting the roof over the plant life increases light intensity which can help to control the development 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 solitary or double level of flexible plastic glazing that operates the space of the greenhouse bay. A small gear engine 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 from bellowing out during windy weather conditions. Opening and closing the roof can be either manual or automatic. Each part of the roof can be controlled independently for flexibility in cooling.
Folding roof greenhouses work very well in snowy climates as they can be tightly shut during winter. Most designs use regular vent hardware. Some have 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 make use of rubber gasketing to seal the joints. Glazing can be glass, polycarbonate or film plastic. Some manufacturers give a movable gutter to collect rainwater when the roof is certainly partially open. Wind sensors should be installed to close the roof in stormy weather. Movable shade is frequently installed with the open roof design. It decreases the heat load by reflecting the suns rays back out. The shade curtain ought to be of a porous style to allow heat to escape. In northern climates an energy blanket can also be installed to reduce heat loss through the winter.
These structures consist of a steel frame, flexible glazing and cable support. Woven UV stabilized polyethylene film produces a watertight glazing. With respect to the cropping system, bracing of the structure can be external cables attached to deadmen, inner compression braces or trusses with cable X bracing. Flat roof designs are utilized where there is small rain 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 shifting the industry leading of the curtain. One gear motor will manage up to 50,000 sq ft of roof Heating is more difficult than in a conventional greenhouse because of the single layer plastic-type and better infiltration through gaps and cracks in the seals.
