They were the most preferred blinds for large spaces and areas where thermal insulation is needed. Since their raw material is PVC, they provide excellent insulation. While preventing the transfer of hot and cold air, they are also one of the rare blinds that allow you to control light. Unlike most other blinds, which must be either fully open or closed, PVC Vertical Blinds offer multiple positions by adjusting the angle of the slats. In addition, the PVC805 model available on www.maviperde.com features two red stripes on a white base. Thanks to its red-striped slats, it adds an aesthetic touch with parallel red lines even when closed.
