Detailed Product Description

Normally, natural ventilation system is installed to keep appropriate temperature inside the greenhouse in spring and fall. Natural ventilation system can help decrease the cost of operation, and meanwhile, by adopting the designated plastic sealing parts, the problem of wind-leak in winter can be resolved effectively. Since that the greenhouse is a semi-closed system, so it can lead to the high density of harmful gases, high temperature and humidity inside the greenhouse, which is perilous to crops.  In order to maintain the normal environment for crops, air exchange is very necessary.
The skylights used in greenhouse include consecutive skylight, alternate skylight and torque-distributive skylight etc..

In some top-grade greenhouses, electrically driven windows for heat preservation are installed behind the wet curtain to keep the freezing cold out, and in spring and fall, those windows can be of the function of ventilation and air exchange.
