VanderValk VSV Curtain Systems
With A1, Langendoen Mechaincal delivers the: ValkScreenVision 2.0. This system makes inserting and replacing screen cloth a lot less time-consuming and less risky for both crop and fitter.
The screen cloths come pre-fitted with guide strips that are pulled directly into the profile as the cloth is inserted. This means that cloth clips will not have to be fitted, and you can insert as much as 3 hectares of cloth per day!
Given that it minimizes the need to move between the crop and work at a height to insert or replace the cloth, it becomes a lot safer and there is no risk of damage to the crop. Inserting can also be left until later with this system, so that the screen cloths will get less dirty with (construction) dust. This will easily mean light gains of 1%, day after day.
Finally, the ValkScreenVision 2.0 system is flexible because it can be supplied with any type of cloth and by any screen fitter or greenhouse builder. So, when changing clothes or building a new greenhouse, you can still choose whatever cloth you want. After all, no one can look into the future.​

Black-out Fabric Curtain Systems
Blackout Curtains Systems are indispensable for inducing flowering in short-day plants in periods when this does not happen naturally. Such curtains prevent daylight from entering the greenhouse. This artificially shortens the length of the day and allows products such as chrysanthemums, gerberas, kalanchoes and medicinal crops to be produced all year round.
Our Blackout Curtain Systems have a blackout ratio of 99.9%. The curtains are also ideal for reducing energy consumption. That kills two birds with one stone.
So, no more worries about your greenhouse climate. The weave of Our Blackout Curtain clothes prevents condensation from forming in the greenhouse. These moisture-regulating properties enable you to maintain the ideal temperature and climate in the greenhouse.
Our Blackout Curtain systems hermetically seal the greenhouse from all incoming light, giving you complete control over the flowering stages of the crop. A light-exclusion all-rounder!
The blackout fabrics are available in various configurations and are all fire retardant.
