A roller is open or closed by degrees. A venetian steers light by direction — tilt up for glare-free daylight under the jacarandas, tilt down for privacy from a double-storey neighbour, close flat when you actually want it dark.
Timber and bamboo venetians, in 50mm basswood slats, are the natural choice on a heritage house — warm, architectural, and exactly what a sash window in a house like this was designed to sit behind. They suit studies, living rooms and any window where "real material" actually matters to the room.
Aluminium venetians earn their place in the rooms timber can't touch — bathrooms, kitchens, laundries — where moisture would ruin a fabric or timber finish over time. In 25mm (crisp, most popular) or 50mm (bolder, fewer lines), with a huge colour range including woodlook finishes, they're the budget-friendly, low-maintenance option for everywhere else.
Steer light direction hour by hour as the sun moves through the tree canopy — no other interior blind does this.
50mm basswood or bamboo slats, the natural material choice for a sash window with real character.
The moisture champion for bathrooms, kitchens and laundries — where fabric and timber both fail.
Available on premium lines, so wide or hard-to-reach windows still get the full adjustable-light benefit.
Timber venetians are heavier than aluminium, so a very wide window may need splitting or ladder-tape support — we'll spec that properly on the measure. Keep timber out of high-steam rooms; a quality lacquer handles normal humidity, but a bathroom still wants aluminium.
Original sash and steel-framed windows run right across this pocket of Johannesburg, so timber venetians turn up in the same kind of rooms in Saxonwold, Houghton Estate, Westcliff and Parktown North that have kept their heritage character.
