How To Build A Greenhouse Roof Vent

This step by step woodworking project is about 8 8 greenhouse roof door and vents plans.

How to build a greenhouse roof vent. Natural ventilation or curtain ventilation uses a series of roof and sidewall vents. Vents in the roof or wall of a greenhouse usually do a good job at passively allowing hot air to escape. This creates a vacuum that draws cooler air into the greenhouse through the sidewall vents located closer to the ground. Roof vents are also good as the hot air rises and the temperature in the greenhouse can be lowered in the summer simply by opening a vent.

When you pair that with opening the main door it creates a nice cross breeze that will draw fresh air through the greenhouse. You can fill in the gaps of the framework with wood except for the roof. The position of greenhouse vents is very important because your goal is to create as much air circulation as possible. The 3 windows are enough to ensure ventilation.

This is part 2 of the greenhouse where i show you how to build the doors and the vents for the greenhouse. Placing two vents on two opposite sides of a greenhouse ensures cross circulation. Use a fan that is encased a waterproof housing with an air. Ideally you want to have cross ventilation so two windows on two sides of the greenhouse work best.

Ventilation for greenhouse roof. And last here is a simple greenhouse design with a sloped roof that allows water to fall on the ground. You can also use fans to create additional air flow such as an exhaust fan. All of which work to some degree and continue to be used to this day but it is hardly is cost effective.

If vents in the roof are not possible make sure to at least have a window to two you can open. This greenhouse has two large doors for an easy access to the interior and four vents so you can cool down the air. Light must get in transparent plastic or cheap glass. As the temperature increases within the greenhouse hot air also rises and escapes through the roof vents.

Natural ventilation for a greenhouse or any translucent roof solar structure has always been the ventilation method of choice.
