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.
We started working with Bob Scavetta until he retired from Agra Tech (after working there for 16 years). Then, we began a relationship with Jim Bergantz. We missed Bob, because he was so knowledgeable, but both gentlemen know the commercial greenhouse industry very well and the information they gave us was exceptional. Jim walked us through the options and helped us to make a series of smart decisions. Jim Bergantz is definitely passionate about what he’s doing and you can sense it immediately. If we ever need a part, Jim knows the solution and will go out of his way to make it happen. They’ve recommended other products and systems for our greenhouses, even though they don’t sell them directly. So, that’s how we know they care, because they’re not all about selling us things. They really want us to succeed, and that’s why we’re happy to be working with them. The customer service at Agra Tech is amazing!
