Temperature Controlled Automatic Greenhouse Window Opener Adjustable 15 to 25 °C for Ventilation Windows up to 7 kg Made of Aluminium and Stainless
You already have the maximum available quantity in your cart.
The automatic greenhouse window opener is a clever assistant that takes care of ventilating the greenhouse even when you are not at home. It operates entirely without electricity or batteries, as it uses a temperature-sensitive piston that reacts to solar heat. Once the temperature in the greenhouse rises, the piston expands, and the window gradually opens, and when the temperature drops, the window closes again. This helps maintain the internal environment within the chosen temperature range and protects plants from overheating and chilling. The opener is made from aluminium and stainless steel, making it resistant to moisture and weather conditions, and it will last outdoors for many seasons. This way, you can care for your plants without having to constantly monitor the thermometer in the greenhouse.
The temperature at which the window begins to open is adjustable between 15 and 25 °C, allowing you to customise ventilation according to the types of plants being grown. Maximum opening occurs at approximately 30 °C, depending on the setting and the load on the window. The opener is suitable for ventilation windows up to 7 kg, making it useful for standard greenhouses and cold frames. The extended aluminium cylinder with a painted finish is weather-resistant and ensures smooth and quiet operation of the mechanism. Installation is straightforward, and the opener can be secured directly to the window frame using the included accessories. Once set, you no longer need to worry about ventilation, as the piston operates independently based on temperature. This saves you time and the need for daily visits to the greenhouse. The opener operates gradually, so it does not open the window abruptly, thus preserving the hinge and the window frame.
Key features of this opener:
- Automatic opening and closing of the window without electricity or batteries.
- Adjustable temperature range of 15 to 25 °C according to plant needs.
- Construction from aluminium and stainless steel resists moisture and weather.
- Suitable for ventilation windows weighing up to 7 kg.
- Low weight of approximately 305 g does not burden the window frame.

The automatic greenhouse window opener saves you the daily hassle of manually opening and closing ventilation openings. Thanks to its sensitivity to solar heat, it responds to weather changes on its own and maintains a more stable temperature in the greenhouse throughout the day. Plants thus always have enough fresh air and do not suffer from overheating or stuffiness during hot sunny days. The opener is ideal for gardeners who spend the day away from home yet want to ensure their plants are well cared for. It can be used in greenhouses, polytunnels, or cold frames with side or roof ventilation windows. For long-lasting use, do not expose it to temperatures above 50 °C and handle it gently when cleaning throughout the growing season.
