A window leaf - a design which is necessary in each greenhouse.
With it, you will create the conditions necessary for the growth of crops in protected ground.
Why do I need a vent
note the fact that the window must be in every greenhouse. Properly done ventilation will not only create the desired microclimate, but also prevent the appearance of pathogens, insects and bacteria on the landings.
It is very important to make a window correctly. in a greenhouse made of polycarbonate, because this material does not allow air. But the sun's rays pass unhindered, the air heats up. So that the plants do not “burn”, make at least two vents. If the greenhouse is large, then the vents may be more.
Ventilator required for hardening seedlings. With this design, you prevent air stagnation, reduce the level of humidity. This is very important for tomatoes and cucumbers, because these cultures most often affect fungal diseases.
Vents are of the following types:
- ordinary mechanical;
- automatic, equipped with an opening system.
You will easily make the valve on your own, special knowledge and expensive tools are not required.

Valve placement options and their installation
Where should be the vents in the greenhouse? If you wish to make holes in the greenhouse for ventilation, then choose places carefully.
Position the vents vertically, placing them in different parts of the greenhouse.
Make one valve at the bottom, and the other - under the ceiling. It is here, at the intersection of the beams is a rectangular area.
Carefully choose the location of the hole. No need to do it from the other sidewhere the wind blows, because it can cause a decrease in the normal level of humidity in the greenhouse. Having made the valve from the side protected from the wind, you will maintain natural circulation in the greenhouse.
How do I know that the holes in the greenhouse are not enough? Pay attention to condensate. If it is on the walls of the greenhouse, then the greenhouse needs to be modernized. Install additional windows, there you will ensure normal air circulation in the greenhouse.
To increase the air flow into the greenhouse, you can make several windows in the upper part, for example, on the roof. This will allow you to quickly complete the airing process. You can install two kinds of devices.:
- automatic;
- manual type.
Automatic will increase the efficiency of the process. They open themselves when the temperature inside the greenhouse reaches a certain value.
When it starts to drop, the valve slowly closes. But it is worth considering that automatic systems are more difficult to install. It is believed that the ventilation system will work highly efficiently if the windows occupy ¼ of the greenhouse area.
Here on the photo options for placement of vents.
What tools are needed?
What tools do you need to make a polycarbonate greenhouse window for your own hands? To make the window, you will need screwdriver and screws. Choose those that have a special O-ring. Buy screws with a wide hat. For processing the edge of the profile, use the file.
Purchase hacksaw, to create a structure useful U-profile. If you cannot buy it, replace the fasteners with perforated tape. To work you will need polycarbonate sheets and scotch.
The choice of attachment is also very important. For windows, use the following mounts:
- on hinges;
- on pivoting mechanisms.
Mounting type greenhouse ventilation is not affected. But when installing automatic systems, it is better to think about this point in advance, this will avoid further difficulties with ventilating the room. Selecting the method, install the vents.
The assembly consists of the following steps.:
- Cut out part of the wall. Work carefully, paying attention to the size of the window.
- Take a profile, use thinner sheets in your work than on the greenhouse itself. Cut a piece. To increase strength, add stiffeners or make a tie using a mounting tape for this purpose.
- Attach the frame to the place where you intend to install the valve. If the edges coincide with the hole, then take a file and process the edges with it.
- Buy a light-colored primer. Cover the structure, or paint it with ordinary paint. This will protect the material from the environment.
- When the frame is ready, screw the polycarbonate. Carefully trim those parts of the sheet that stand out of the outlines of the frame.
- Take a sealant or adhesive tape. Carefully cover all joints with them. Carefully protect the lower edge of the structure. If you wish, glue the edges of the vents rubber.
- Attach the hinges and put the turntable with the limiter, which will serve as a lock.
- Install the vent.
