Control is essential for modern apartment windows, and vertical window blinds are the obvious window covering solution.
As well as clean lines, they can be subtly adjusted to manage the view (whether you want to obscure it or keep others peering into your place).
A wide range of transparencies, plus the control of motorised blinds for smart home automation such as Powerview®, can be combined for very nuanced levels of control.
Add into the mix the choice of vane widths to determine the amount of light and visibility, and they become one of the most versatile options.
