The Agra Tech Sawtooth Greehouse is a low profile single slope truss. Heated air travels up the roof slope away from the plants.
The two biggest advantages of the Sawtooth design are that it is easy to install exhaust fans mid-house in the vertical wall above the gutter and that it is designed with columns that can continue through the roof to attach an energy truss outfitted with an exterior curtain.
With a vent or opening wall on the windward sidewall and vent on leeward roof, excellent natural ventilation is achieved for happier plants and reduced cooling costs.
It hasn't been easy along the way for the Caribe Greenhouse Project. The buildings went through two hurricanes (Maria and Irma) during the construction and according to the company's licensed inspectors and engineers, there was little to no damage to the greenhouses. "The structures were half-built when the storms came, but they held up fairly well, which was impressive," Cabiya said. "They are made with sturdy and reliable components, so they only experienced only a few minor issues."
