Frequently asked questions

It sure is! We have done various projects, including for chrysanthemum growing and also cannabiscultivation, where the screen system was made up of as many as three layers of cloth! With other systems, the cloth clips may snap off when using multiple cloth layers. Not with ValkScreenVision! Because the cloth strip is attached to the cloth.

This is so as to prevent wear on the ValkKliMax and the reversing wheel. Expansion/shrinkage of the screen profiles may lead to the standard ValkKliMax slip systems ending up misaligned with the reversing wheels when opening and closing the screen. Since the ValkKliMaxcan slide along the screen profile, it always ends up aligned with the reversing wheel. It also means that dilation joints are no longer necessary, which saves time and money!

To protect the polyester wire. The double tab ensures that the polyester wire stays well centred. This way, the wire will not touch any sharp edges and will last a lot longer.

When installing a screen system in a greenhouse, the pull wire has to be wound around the ValkWireSleeve. With a section size of 5 metres, for example, it has to be wound 24.5 times. You don’t have to count this, however, as you can just stop when the wire reaches the outer hole in the ValkWireSleeve!

- The ValkLockPin can be installed with one hand. After you hear the ‘click’, you know that the window raiser has been fastened to the ventilation window.

- A standard locking pin requires an additional action. The tabs at the end of the pin have to be bent manually. People sometimes forget to do this, meaning that the window raiser has not been secured.

This is to absorb tolerances of 2mm x 8mm (1).
The depth of the clip bracket (2) actually also provides more clamping force on the tube.

This is to prevent the rod from freezing and breaking during cold spells. Thanks to this hole, moisture cannot accumulate and freeze.
