Some crops need to be stimulated by controlling night and day light conditions. That need to use blackout screens which can create total darkness inside the greenhouse.

Most models are made of double-layer screens, and the front and back surfaces of the inner and outer screens can be selected according to the application. For example, the aluminum foil material has the characteristic of reflecting infrared rays, and has good energy saving at night; the white surface has excellent light reflectivity, and the white surface facing the outside during the day can reflect sunlight, weakening the greenhouse effect caused by solar radiation, and night. The inwardly facing white surface reflects artificial illumination to enhance artificial light efficiency; the black surface absorbs and blocks light well. Our screens are available in both flame retardant and non-flame retardant versions.
