Answers about Grinotex®
external venetian blinds

What sets the Grinotex® apart from other external venetian blinds?

The Grinotex® uses sine-wave slats made of a metal composite, a proven system that offers particularly high wind stability. The wave-shaped slat geometry ensures an even distribution of daylight and directs the light into the room in a controlled way.

Is the Grinotex® also suitable for strong winds?

Yes, that is precisely its strength. The Grinotex® is designed specifically for wind-exposed locations. Thanks to its sturdy metal-composite construction, it remains stable even in stronger winds and does not have to be retracted at every gust.

How well does the Grinotex® black out a room?

Since there are no open punch-outs for textile tapes, the direct passage of light through the slats is greatly reduced. For complete darkness, some light may still enter at the sides due to the design. Anyone who needs full blackout is better served by the Metalunic®.

Does the Grinotex® have a soft-close function?

Yes. The Grinotex® features a gentle end-position cushioning (soft-close), which makes operation quieter and protects the mechanism. This is particularly pleasant in motorised operation.

What are the maximum dimensions possible for the Grinotex®?

The Grinotex® can be manufactured up to 8 m² in size and up to 400 cm wide and 425 cm high. This means it reliably covers even large window fronts.
