In addition, it reduces electricity costs as expensive lover cooling is not needed.
Several methods are accustomed to open the roof. Some manufacturers make a roof that opens by rolling up the one or double layer of flexible plastic material glazing that runs the length of the greenhouse bay. A little gear electric motor rotates a shaft that winds the plastic material on to it just like a window color. 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 side of the roof can be controlled independently for versatility 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 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 about 85%. Most designs make use of rubber gasketing to seal the joints. Glazing could be cup, polycarbonate or film plastic. Some manufacturers give a movable gutter to collect rainwater when the roof can be partially open. Wind sensors should be set up to close the roof in stormy climate. Movable shade is generally installed with the open roof design. It reduces the heat load by reflecting the suns rays back out. The shade curtain should be of a porous style to allow heat to escape. In northern climates a power blanket may also be installed to lessen heat loss during the winter.
These structures consist of 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 framework can be external cables attached to deadmen, internal compression braces or trusses with cable X bracing. Flat roof styles are used where there is little rain or snow. A-roof styles shed the rain and snow to an internal gutter system. Designs which will carry up to 35 lb/sq ft snow load and 100 mph wind loads are available. The roof opens in sections by shifting the leading edge of the curtain. One gear motor will deal with up to 50,000 sq ft of roof Heating is more difficult than in a conventional greenhouse because of the single layer plastic material and greater infiltration through gaps and cracks in the seals.
