Poly Arch - Model SQ - Commercial Greenhouses
The Poly Arch by Rough Brothers has been designed and field-tested to meet your demanding environmental needs. Whether utilized for production or retail, the energy efficient roof-vented Poly Arch will provide the environment you desire while providing you with the most economical gutter connected structure. Suitable for natural or fan ventilation, the Rough Brothers Poly Arch has a unique roof vent design which allows for maximum cooling: the bottom rail of the vent opens above the ridge, eliminating trapped hot air. An additional benefit of the raised bottom rail is the ability to easily vent regardless of outdoor conditions.

Designed to readily accept hanging baskets, lights, booms, echo systems, and other needed equipment, the Rough Brothers Poly Arch truss system can be designed to support each piece of supplementary equipment without additional structural members. This truss has also been designed for use with heat retention and shading systems, minimizing summer heat gain and winter heat loss.
With the exclusive Rough Brothers bowed sidewall, you will benefit from added growing space immediately, while having the necessary components to expand later. Since the optional bowed sidewall utilizes standard Poly Arch components, expansion is easy with the addition of posts and gutter.
The Rough Brothers Poly Arch is available in standard and custom widths to suit your needs. Standard sizes include 20'6', 36', and 41' wide.
