Faux Wood Blind
A moulded composite slat with a printed wood grain. It gives you the look of a wooden blind on the windows where real timber would fail: a kitchen full of steam, a bathroom, a balcony door, any window that takes rain sideways in July.
It is heavier than natural wood, which is why the maximum width here is lower — beyond that span the weight makes the blind hard to raise and hard on the mechanism.
