The present invention relates to curtains that include a curtain rod (1) which is mounted on at least two brackets (2) and along which free-hanging vertical suspensions (3) are provided. The suspensions are made in the form of elongated members having a curved cross section and made of a resistant and elastic plastic material, wherein said suspensions are arranged along the curtain rod so that they essentially rest tightly upon one another. The material used for the suspensions may have various colours and/or levels of transparency. These curtains prevent insects and the light, inter alia , from penetrating into premises and further have a decorative effect.
