Our Blackout Vertical Blinds compliment our broad color range of Blackout Roller Blinds. The effect of complete darkening of large window space will be more affordably achieved with our collection of vertical blackout blinds. These can be joined seamlessly in the middle to cover exceedingly wide windows eg in office space. Blackout Vertical blinds come in several universal colors and following louver widths: 89mm and 127mm. They are relatively lightweight and will be a natural choice for larger windows. Blackout Vertical blinds enable easy and sharp light control allowing privacy or full darkening effect.
