Blackout blind for Dakstra roof windows – Description
This blackout blind for Dakstra roof windows delivers complete room darkening and superior heat control, making it essential for bedrooms, children’s nurseries, and home attic offices.
Manufactured by the same company that produces Dakstra windows (Altaterra – part of the VELUX group), this genuine factory blind guarantees a seamless, precise fit with zero light gaps and effortless DIY installation.
Built with a multi-layer rubberised fabric, the blind reliably seals out direct daylight across all colour options to create an ideal sleep environment. The slim aluminium side rails (only 2.9 cm wide) maximise daylight when open while preventing light leakage along the sash edges. Additionally, the reflective white exterior backing helps reduce solar heat build-up, making your loft more comfortable during summer.
To improve comfort in summer, consider combining this blind with the external awning for Dakstra windows, which reduces attic overheating while still letting in daylight. For high-set windows, our telescopic control rod eliminates the risk of household falls, allowing you to operate blinds safely from floor level.
Why choose this blackout blind for Dakstra?
Never measure the glass — blinds are chosen strictly by the Dakstra window’s data plate code.
