A greenhouse is most commonly covered with horizontal screens and roll façade screens. By this choice the temperature-repartition is optimized.
For blacking out the greenhouse, or minimizing the light emission a roll-façade screen is essential. The newest greenhouses are already prepared for this kind of screen-systems. It can perfectly be integrated in the greenhouse-construction.
Solar reflection can be obtained between 20 to 100%. Roll-façade screens can alo perfectly be used as separation-walls in the greenhouse. Driven by internal or external engines. As a whole or in several partitions And as the screen-technique is optimized, no leaks will occur, so no light or draft will come through. And the screens do not shrink.
