Description

You get the best of both worlds with a Dual Atrium — a protected greenhouse environment with convenient outdoor access for crop conditioning and steering.

The Dual Atrium works well as a passive-cooled house with double the roof ventilation of the Vail Atrium. Unique roof vents open upward and outward for air removal and to prevent heat build-up for optimal air mixing without crop stress.

Crack the vents during storms without fear of rain getting in the house. With ample light for crops, the Dual Atrium is a great choice for multi-tier production.

When you build a Dual Atrium greenhouse, you get:

  • Indoor protection with outdoor benefits
  • Strength for peak performance
  • Adaptability at its Core

 

Highlights

  • Maximize Light: The 42′ wide-span two-peak truss design allows for superior light transmission and ventilation.
  • Manage Plant Growth: Create a near-outdoor environment for crop conditioning. Easily adjust climate and temperature for crop steering to reduce PGR use.
  • Vent in Inclement Weather: Partially open roof for de-humidification with a rain guard and peak gutter that catch precipitation. Rapid roof closure in less than three minutes.
  • Handles the Weather: Meets regional wind and snow load requirements.
  • Provides Stability in Wind: High-quality, heavier extrusions hold up to strong winds while the vents are open. Added strength at crucial stress points in windy conditions with double-tooth steel rack arm.
  • Operates in Winter Conditions: Roof vents hinge halfway up roof slope for ventilation even with snow or ice build-up in the valleys.
  • Lasts for Generations: Triple-galvanized U.S. square steel for strength and longevity. Aluminum extrusions and flashing for a long-lasting clean finish.
  • Integrate Overhead Equipment: Exposed truss bottom cord, even with a flat shade system installed, allows for multiple types of overhead equipment (e.g., heaters, fin-tube, basket systems, irrigation, supplemental lighting, etc.)
  • Boost Curb Appeal: Great option for year-round passive retail ranges in more temperate climates. The Dual Atrium’s impressive dominating profile from a distance demands attention from street traffic.
