Cravo Retractable Roof Greenhouses/Shadehouses
Over the last 29 years, Cravo has developed a wide range of A Frame and Flat
retractable roof houses and coverings to suit your crop, climate and budget.
Cravo retractable roof houses are in operation in cold climates with heavy
snowloads, in the hot, dry arid conditions of the desert, and the hot, humid and
windy conditions of the tropics. In fact, Cravo houses have been hit by 7
hurricanes, without loss of any structure or roof covering. You can be assured of
a long trouble free operation since drive systems are mostly made of stainless
steel and aluminum, and the retractable white and clear roof coverings have
proven useful lives of 8 to 12 years depending on climate, use and crops being
grown. Cravo roofs also require minimal electricity since one 2hp motor can
power approximately 1 hectare of flat roof and .5 hectare of A frame roofs.

Choosing the sidewalls
Opening of the walls on a greenhouse with a roof that retracts has proven to be beneficial to create the best possible
growing conditions. Not installing roll up curtains on the sidewalls was one of the frequent mistakes made by the early
users of retractable roof greenhouses. While motorized roll up curtains are initially more expensive compared to
stationary or seasonally removable poly, they allow the growers to maximize their return on investment since they are
able to almost instantly create the full range of environments possible. The sidewall design is not normally influenced by
whether the roof is an A frame or flat roof.
Closing the sidewalls allows:
Plants to be quickly protected from damage due to high winds or a cold front blowing in
Crops to be uniformly irrigated if using overhead irrigation
Better penetration and reduced drift of chemicals since the wind will be blocked
Opening up the sidewalls allows:
The greenhouse to be ventilated through the sidewall when it is raining and the roof must be closed
The greenhouse to be cooler in the summer regardless of whether the roof is closed partway for shading or totally
retracted
Re-entry times after spraying to possibly be reduced by being able to create an outdoor environment
To determine the right sidewall design for your application, the following questions need to be answered:

Should all 4 walls be able to be opened or just two opposing walls? If only two walls are to open, they should face the
prevailing wind.
Should the roll up curtain close to the grade or to a knee wall?
Roll up curtain extending down to the ground
Allows for easy access by people or machine through the sidewall.
Roll up curtains work well with retractable roofs since the roof is the primary ventilation. Growers tend not to have
problems with the opening being on the bottom since the walls are normally not open until after the roof.
