Commercial Greenhouses: The Zail Greenhouse

The Zail™

Commercial Greenhouse

Superior Cooling and Dehumidification:

Hot air escapes at the highest point in the greenhouse, not at the lower gutter area, as in a gutter vented design.
Top ridge vents allow for dehumidification even when snow is in the gutters.
The combination of the Zail vertical ridge vent and side/endwall vents eliminates the need for exhaust fans and reduces dependence on high-cost electricity.

Peak Profits:

Grower experience in this house indicates the ability to hold outside ambient temperature in the greenhouse without use of mechanical cooling.
Zail trusses are factory welded using galvanized steel to offer consistency in dimension and ease of site construction.
With one-piece trusses, we ship fewer parts and your greenhouse goes together much faster. Therefore, you get big savings during construction.
The strength of the Prospiant pioneered, welded truss design gives you flexibility to hang baskets, vegetable crops and equipment increasing the amount of crop that can be grown in the same square footage.
The Zail vent design allows for easier installation of bug screening at the vent.

Designed to Meet Local Wind and Snow Load Requirements:

The Zail can be designed to meet your regional snow and wind load rating by our licensed professional engineers.

Covering & Vent Options:

The straight roof truss design allows for a variety of roof coverings: Lapped glass, twin wall or corrugated sheets.
Vent options include: drop down curtains, glass, multiwalled panels or corrugated covered rack and pinion vents.

TOP VENTING – PEAK PROFITS

A Zail is a gentle breeze. The Zail™ is the most cost-effective solution for natural ventilation because it is designed and constructed to meet your specific requirements (i.e., regional snow load rating) and it offers the grower a gentle breeze to help optimize growing conditions.

FASTER PROFITS

The Zail’s one-piece, preassembled trusses easily attach to the square columns and predrilled color-coded square purlins for more uniform and faster site construction. The strength of the pioneered, welded truss design gives you flexibility to hang baskets, vegetable crops and equipment.

VERTICAL VENTING — FAR SUPERIOR

The Zail offers an improved cooling solution to an old problem by use of efficient vertical ridge vents at the peak. In the Zail, hot air escapes at the highest point in the greenhouse, not at the lower gutter area as in a wing design. Top ridge vents allow for dehumidification and ventilation even when snow is in the gutters. The Zail’s vertical vent design protects your crops from heavy rains and minimizes the risk of losing vents in the roof from high winds. Also, insect screens install in a snap.

FLEXIBILITY BY DESIGN

Vent options include drop down curtains, polycarbonate (twin wall or corrugated), or fiberglass covered rack and pinion vents. Greenhouse options are: double-poly or rigid covering when ordering, with the option of adapting double-poly to a hard cover later.
