Westbrook Greenhouse Systems' Apex line has a new venting system for double-poly covered greenhouses. The Peak Vent allows for maximum venting and first-stage cooling, even when there is snow in the gutters.
The new MXIII greenhouse from Van Wingerden Greenhouse Co. provides a unique style of naturally ventilated greenhouse using inflated double poly, providing an economical alternative to other mechanical systems. With an increase in insulation value of the double poly and the use of natural ventilation, the MXIII provides assistance with energy concerns. Opening the middle peak on a 36-foot bay provides adequate ventilation and reduces up-front costs.
