Velux Duo Blinds offer you the best of both worlds. You can block out as much of the light as you want with the Blackout blind, then use the semi-opaque Pleated blind to diffuse the rest of the light that enters the room.
You can either use the entire Blackout blind element of the blind-thus completely blacking the light out of the room, or all of the Pleated blind element-diffusing the light that enters through the window. Or you can have part of each showing, else completely closed the whole blind.
The Blackout blind comes with an aluminium backing which prevents heat loss and heat gain. This can help improve the insulation of your window by up to 20%*, making it more energy efficient.
A combination of Blackout and Pleated blinds.
Choice of four colour combinations.
