Horizontal slats that tilt to steer light — full view, filtered light, or full privacy, at any height, as the sun swings around the ridge through the day.
25mm slats give the crispest, most popular look; 50mm slats are bolder with fewer lines across the glass. Aluminium is the clear choice for bathrooms, kitchens and laundries, and its powder-coated finish handles the wind and grit that come with a ridge-top position far better than fabric. A woodlook finish is available if you want the timber look without the timber price.
50mm basswood or bamboo slats suit studies, formal rooms, and Northcliff's older, more character-driven interiors — anywhere "real material" matters more than minimalism. Keep timber out of high-steam rooms; a quality lacquer handles normal humidity fine. Very wide windows need splitting or ladder-tape support, since timber runs heavier than aluminium.
A roller is open or closed by degrees; a venetian steers light by direction. Tilt up for glare-free daylight when the afternoon sun swings low over the ridge, tilt down for privacy from a neighbour's double storey, close flat for full dark. Houses with hour-by-hour sun swings — exactly what a ridge orientation gives you — get more day-to-day use out of a venetian than almost any other product.
Aluminium and timber venetians go up across the ridge and its neighbouring suburbs — a regular fit in Blackheath, Fairland, Weltevredenpark and Windsor, wherever a room needs the light steered rather than simply blocked.
