VELUX DKU Blackout Blind — Description
The manually operated VELUX DKU blackout roller blind is a classic solution for achieving total darkness in attic rooms with older plastic roof windows, especially the popular white VELUX GGU model. It is specifically designed for pre-2000 VELUX polyurethane and plastic models GGU, GHU, GPU, GTU, GUI and VIU.
The DKU blackout roller blind is ideal wherever you need to completely block incoming light – from watching a movie on a bright summer evening to ensuring a restful sleep at any time of day. Perfect for bedrooms, children’s rooms and guest rooms in the attic.
The fabric runs in slim natural aluminium side rails that prevent light leakage at the edges, providing a tight, light-proof seal between the roller blind and the window frame. For extra heat protection in hot months, you can combine the VELUX DKU roller blind with a VELUX external awning blind.

FAQ: VELUX DKU Blackout Blind (Expert Answers)
Is the DKU rollerblind suitable for my current VELUX GGU window?
The VELUX DKU blackout roller blind is intended for older, pre-2000 plastic and polyurethane windows such as GGU, GHU, GPU, GTU, GUI and VIU. If you have a newer generation GGU window, you should choose the standard DKL blackout roller blind instead.

Yes. The combination of blackout fabric and tight-fitting aluminium side rails delivers a near total blackout effect, with no significant light gaps around the edges when correctly installed. This makes it ideal for bedrooms and home cinemas.
In which colours is the DKU rollersblind available?
The DKU blackout blind is available in three classic colours: light beige (1085), white (1025) and navy blue (1100). All colours offer the same blackout performance – the choice is purely decorative.
Can I install the DKU roller blind myself?
Yes. The blind is designed for DIY installation using the original VELUX Pick&Click!® brackets pre-installed in the window. With a screwdriver and the included instructions, most homeowners can complete the installation in less than 15 minutes.
