he Multi-Fit DUA Blackout Blind is a practical and reliable roof window blind designed to give you complete control over the amount of daylight entering your room. Ideal for bedrooms, loft conversions, nurseries, home offices and living areas, this blackout blind helps create a darker, more private and more comfortable space throughout the day and night.
The smooth adjustment mechanism allows the blind to be positioned exactly where you need it, so you can reduce glare, soften sunlight or fully close the blind for maximum darkness. When closed, the blackout fabric blocks virtually 100% of incoming light, making it a great choice for sleeping areas, media rooms and bright loft spaces.
Manufactured from durable, dirt-resistant material with high-quality aluminium side guides, the DUA blackout blind is built for long-lasting everyday use. It offers a neat, secure fit inside compatible roof windows and is backed by a two-year guarantee for extra peace of mind. RoofLITE+ confirms the DUA blind uses durable, dirt-resistant material, aluminium guides and is backed by a two-year guarantee.
For improved year-round comfort, the DUA blackout blind can also be combined with a compatible MIA external anti-heat blind on selected roof windows. This combination helps improve privacy, room darkening and thermal comfort, especially in sunny rooms and loft spaces.
