A Cabrio greenhouse combines the benefits of greenhouse cultivation with the benefits of outdoor cultivation. This is, of course, conditional on you being able to open the greenhouse roof fully and stably.
The ValkCabrioRail ventilation mechanism by Van der Valk Horti Systems meets this condition effortlessly. This system sets itself apart from other systems because of the two push/pull tubes arranged either one above the other or next to each other, and because of the unique patented telescope structure for maximum ventilation capacity.
Key system benefits:
ValkCabrioRail is available as type 2, 3 and 4, which have the following features in common:
In the Type 2 Cabrio, the ValkStabiMax hinge ensures a strong connection between the ValkPushRods and ValkDriveTube.
The ValkRailBracket guides the ValkDriveTube.
The ValkPushRod is the rod used to push up the ventilation window and works best in combination with the ValkStabiMax hinge.
To achieve the required stability, types 3 and 4 of the ValkCabrioRail ventilation mechanism use steel window push rods, combined with the aluminium Delta ValkPushRod.
With three different drive types to choose from, you will always get the right system for your greenhouse!
Two push rods move simultaneously on the upper and lower tube. The structure is combined with ValkPushRod window push rods and the ValkStabiMax hinge element.

The ValkCabrioRail ventilation mechanism is calculated completely for each situation using the unique WinTop calculation program, which was developed in partnership with TNO, the Netherlands Organisation for Applied Scientific Research.
Based on various variables (the geometry of the roof, the maximum local wind load, the required opening angle, etc.), all factors that may affect the system’s reliability are calculated. Such factors include the required structural strength, clearance between the mechanism and the roof structure, and the position of the rail consoles and rack and pinions.
We can, of course, tell you all about how great our product is, but we prefer to leave that to our partners, who have been using our systems for years.
