energyclimate-controlroller blind

Flame retardant, rolling screen for light diffusion and energy saving HARMONY 4445 R FR is a white rolling screen with a closed structure. By day it reflects sunlight, keeping the greenhouse cool, while its white strips also provide a high level of light diffusion – bringing light to the plants from many more angles and stimulating growth. By night it helps to retain heat, maintaining a steady temperature and saving energy. The steadier temperature minimizes formation of dew on the crop, reducing the risk of fungal diseases. For extra ventilation, an open structure version is available. This product is made from flame retardant materials alone, this is the optimum choice for all installations from a fire safety perspective. It meets the highest safety standard in the horticultural industry and test reports are available from various authorities.
