Description

Commercial Greenhouse

Growing success begins with a Poly Arch greenhouse. Suitable for natural or fan ventilation, the Poly Arch has a unique roof vent design that allows for maximum airflow and cooling.

The Poly Arch has been designed and field-tested to meet demanding environmental needs. Whether used for production or retail, the energy-efficient roof-vented Poly Arch will provide the environment you need and the most economical gutter-connected structure.

Suitable for natural or fan ventilation, the bottom rail of the air vent opens above the ridge, eliminating trapped hot air. The raised bottom rail provides an additional benefit in its ability to easily vent regardless of outdoor conditions.
