The blackout blind with lateral guide rails is the perfect accessory for windows with Velux. Original Velux components now no longer need to be dismounted prior to the blinds being hung above the window. The lateral guide rails, the shutter with its roller blind cassette and the operating profile are all made of high-quality, stable aluminium profiles. The blind can be reliably set in any desired position. The silver-coated rear of the fabric ensures the maximum level of darkening. It also reflects the warming sunlight. This blackout blind is opaque, making it ideal for bedrooms - even in broad daylight it will darken your room significantly. The blind is delivered including mounting instructions and mounting hardware. The material can be wiped clean. It is UV- and moisture-resistant, non-fading, and thermoplastic coated.
