Description

The Zephyr works well for both production and retail settings. It is the ideal choice for natural ventilation and dehumidification. The Zephyr’s curved roof shape and peak vent allow heat to escape from the top of the house, eliminating the need for exhaust fans and vents, even with the gutters full of snow.

Sidewall heights leave ample room for equipment such as booms, shade systems, and hanging baskets. The curved truss design gives you the flexibility to start with a poly-film covering and retrofit to a hard covering later.

 

Highlights

  • Top-mounted vertical roof vents and drop curtains allow hot air to escape from the highest point of the greenhouse, not at the lower gutter area as in other designs.
  • Ability to hold outside ambient temperature in the greenhouse without the use of mechanical cooling.
  • Poly covering offers a high degree of insulation in colder climates.
  • Vertical vent protects crops from heavy rains and minimizes the risk of losing vents to high winds. Insect screens install in a snap.
  • Winter dehumidification improved by letting only the hottest air at the peak escape while maintaining warm temperatures at the crop level.
  • The strength of the welded truss design gives you the flexibility to hang baskets, vegetable crops, or equipment.
  • Designed to meet local snow and wind load specifications.
