Open roof greenhouses give a natural environment for plant growth when the outdoor weather conditions would work and an artificial environment when it’s too hot or frosty. Opening the roof over the plants increases light intensity that may help control the development habit, flowering and crop timing. It also reduces electricity costs as expensive lover cooling isn’t needed.
Several methods are accustomed to open up the roof. Some manufacturers make a roof that opens by rolling up the single or double level of flexible plastic-type glazing that runs the space of the greenhouse bay. A small gear engine rotates a shaft that winds the plastic 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. Opening and closing the roof can be either manual or automatic. Each part of the roof can be managed independently for flexibility in cooling.
Folding roof greenhouses work very well in snowy climates because they can be tightly shut during cold weather. Most designs use regular vent hardware. Some possess 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 make use of rubber gasketing to seal the joints. Glazing can be glass, polycarbonate or film plastic-type. Some manufacturers give a movable gutter to collect rainwater when the roof is definitely partially open. Wind sensors should be installed to close the roof in stormy weather. Movable shade is generally installed with the open up roof design. It decreases the heat load by reflecting the suns rays back again out. The color curtain should be of a porous style to allow heat to escape. In northern climates an energy blanket may also be installed to reduce heat loss during the winter.
These structures contain a steel frame, flexible glazing and cable support. Woven UV stabilized polyethylene film creates a watertight glazing. Based on 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 styles are used where there is little rain or snow. A-roof styles 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 Gearbox For Greenhouse moving the industry leading of the curtain. One gear motor will manage up to 50,000 sq ft of roof Heating is more challenging than in a typical greenhouse because of the single layer plastic-type and greater infiltration through gaps and cracks in the seals.
