Open Roof Greenhouse

Space-efficient Mass Production House

The Open-Roof greenhouse provides a protected environment with easy outdoor access for crop conditioning and steering. It has excellent ventilation and can accommodate multiple glazing types. Its unique roof design features full vertical vents that pivot at the gutter sides for 86° natural ventilation with the roof fully open, or partial roof opening during bad weather. The peak gutter keeps unwanted moisture off the crops.

Optimal Growing Conditions

  • Amplifies natural light: The tempered-glass exterior minimizes light loss, while allowing for higher light transmission.
  • Delivers optimal ventilation and airflow: Higher ceilings and shallow peak heights offer greater floor-to-vent room for increased air volume, improved airflow, and a healthier growing environment. Houses can be actively or passively ventilated.
  • Minimizes moisture: Condensation channeling to the gutters negates drip damage to crops.
  • Provides heat protection: High sidewalls provide a natural heat buffer for the crop and increase production space. Shade curtains retain heat in winter and protect crops from the summer sun.

Stands the Test of Time

  • Durable weather protection: Stands up to heavy snow, wind, and crop loads.
  • Reduces maintenance: Tempered glass minimizes reglazing and upkeep.
  • Lasts for generations: Hot-dipped galvanized North American square steel for strength and longevity.
