Reed is a natural material designed to increase your privacy - in a pergola or in the garden. It is also suitable as protection against noise dust and wind. The reed is dried and tied with a binding wire, which functions as reinforcement and allows its use as a shading on the fence.
Reed is a material that is very malleable but also fragile at the same time. Over time, the material turns black. It is not a defect of the material. It is because the material is natural and therefore changes in sunlight.
