The introduction of duo blinds has revolutionised the classic roller blind. With two parallel fabrics working together they enable the element of light control to roller blinds that cannot be achieved by a standard roller blind. The two fabrics work together by being stripped with one translucent mesh or voil stripe and one opaque coloured strip on each fabric, therefore when you pull the blind down you have options of having them blind fully closed and opaque for privacy or can have them down with the voil stripes in unison and creating a translucent striped affect enabling light in whilst providing privacy also.
