Blackout blind for Keylite roof windows – product details
This blackout blind for Keylite roof windows provides effective room darkening and reliable heat reduction, making it ideal for bedrooms, children’s nurseries, and attic home offices.
Crafted with multi-layer rubberised fabric, the blind effectively blocks direct daylight in every colour option to support an optimal sleep environment. The slim aluminium side rails (just 2.9 cm wide) preserve natural light when raised while stopping light bleed along the window edges. Furthermore, the reflective white external backing reduces solar heat build-up, keeping your attic space cooler during warmer months.
Why choose this blackout blind for Keylite?
