Wooden venetian blinds blinds are a great contemporary window treatment, that offer a clean, uncluttered look in a window. However, there are some things to be aware of to ensure that your blinds are suitable for your window. Wooden blinds are a natural product, and as such are no different to any other wooden product. While the slats are coated and are warp resistant, using wooden blinds in a room with a high moisture content such as bathrooms can cause the slats to warp slightly. In rooms with a high moisture contact, a faux wood or aluminium blind might be better choice.
