Through four set positions: closed, 33%, 66% and fully open. Closed gives a weather-shedding roof that carries rain to the gutters; the middle settings filter light and let warm air escape upward; fully open leaves the sky visible between the slats.

Yes. Systems link into one structure with shared posts and drainage, so a wide louvred system can run alongside a glass one and give you two quite different spaces under a single roofline. The run is planned as one structure at survey.

A Teleco remote comes as standard, with the four slat positions on the handset, so the roof is adjusted without leaving your seat. Integrated LED sits in the gutter and runs from the same control.

When closed, the blades overlap to form a weather-shedding roof that channels rain into the integrated gutters and post drainage, so the space beneath stays dry in normal rain. In wind-driven rain a little spray can reach the open edges, as with any louvred roof, which is what side screens are for.

Yes, they are specified separately. Frames come in traffic white, grey or black, and slats in anthracite, black or traffic white, so a grey frame with traffic white slats is as straightforward as a matching finish.
