Black Out Rolling Screens

Ridder Black Out (RBO) rolling screens extend complete light exclusion to the vertical walls of the greenhouse, ensuring full blackout conditions for photoperiod-sensitive crops. While roof blackout screens block overhead light, blackout rolling screens prevent unwanted light from entering through the sides, creating a fully controlled environment essential for crops such as chrysanthemum, kalanchoe, poinsettia, and cannabis. They maintain the same 99.9% shading efficiency as Ridder’s overhead blackout screens. This ensures precise day length control, vital for flowering and yield optimization.

Moving beyond the blackout effect - these screens also improve energy efficiency by reducing heat loss through the greenhouse walls. Installed together with boundary material and sewn on overhang materials extending from the overhead screen panels, they help form an energy-tight seal around the crop. Rolling screens are offered in white and black versions that are flame-retardant. A non-flame retardant, more light weight black version is available and perfect for use in partition walls within the greenhouse.

Overall, RBO rolling screens offer growers a complete, adaptable solution for blackout, climate stability, and energy savings year-round.
