In the Netherlands, not many new greenhouses will be built. Therefore, the activities of the greenhouse suppliers will change. This is also the case for SchermNed, a Dutch company that supplies screens. Carl Stougie explains three popular investments. “Relatively small, but with a big impact.”


According to SchermNed and it's clients, maintenance of air mechanisms is an important tool to save money. Maintaining your screens is essential. A screen that is not functioning is a huge obstacle. By maintaining and controlling the screens on an annual basis, no unexpected problems or costs will occur. Also air mechanism, roof ventilation and the maintenance and monitoring of the rotating parts, are part of their tasks.

Fixed plastic underneath the screen

The second popular investment is fixed plastic underneath the screen. This can be used as an alternative for installing a second screen. According to Stougie, the investment is relatively low and the warmth will be kept inside the greenhouse. However, for the installer this trend has a disadvantage; the period to work on the screen installation becomes shorter. “After the summer break, the growers start thinking about their new greenhouse and what needs to be done. First, they will make a choice about the substrate, afterwards the heating possibilities and finally the screens need to be installed. Due to the small size of the company, SchermNed is able to work quickly and is able to offer quality and security. “Therefore we are able to take care of these situations quickly, when dealing with a tight schedule.”

Roof-ridge screens are gaining popularity

Finally, roof-ridge screens are getting more attention. With these foils, the airflow will be stopped at the roof-ridge of the greenhouse. “This is also a relatively low investment to improve the climate in the greenhouse” says Stougie. Other possibilities to stop the airflow are using fans or turning the heat on. The roof-ridge screens can be installed in new and old greenhouses. Moreover, the height of the greenhouse does not matter. Vegetable growers are already convinced, but demo projects need to be designed for the ornamental growers. According to Stougie, the potency is large in this sector.



Besides these activities, research and innovation is important for SchermNed. SchermNed works on practical problems that are coming across. An example is SunMax. Sunmax is designed by Van der Valk for the ID-greenhouse from Duijvnestijn Tomaten. The SunMax-system provides a larger amount of light then standard screens. Besides, the ID-greenhouse is equipped with roller screens and windbreak nettings. “Also with these kinds of projects, being a small company has many advantages: it's easier to make quick decisions and to reach the right person. We learn a lot from these projects.”
