Rack & Pinion Side Roof Vents

Greenhouse Cooling & Ventilation

Traditional rack and pinion vents allow for natural ventilation as an inexpensive means of cooling. With the use of atrium roof vents, the clear opening to the sky quickly allows the hot air to escape into the surroundings. 

In conjunction with side inlet vents and shade curtains, greenhouse temperatures can be less than the outside ambient temperature.

The inlet vents may be guillotine vents with clear openings or the old-style rack and pinion. The quiet environment of natural ventilation is a great shopping experience in a retail garden center as compared to noisy fans.

Affordable cloth curtains will give you an economical natural ventilation option in the roof or the walls.
