With a combination of Blockout and Sunfilter fabrics on a double bracket, Dual Roller Blinds give privacy and heat management during the day and night, giving you the best of both worlds at your window. If you aren’t using them, roll them away. Dual Roller Shades combine two shades, one of which is placed in front of the other. One for the front shade and one for the back shade; choose two Designer Roller or Designer Screen fabrics. Using materials with varying degrees of opacity allows for the most light control and privacy.
