ABSTRACT OF THE DISCLOSURE A greenhouse screen with high light resistance and good weathering characteristics. The purpose is to achieve a green- house screen which combines the characteristics of a shadow cur- tain and a blackout curtain and in certain cases also an energy curtain. These goals have been achieved through letting the screen at least partly consist of a material which in one or more layers is sunshine absorbing in a significant part of the wave- length interval 575-800 nm, preferably with a maximum in the interval 600-750 nm, while the photosynthesis light of the sun- shine in the wavelength interval 400-575 nm is mainly transmitted through the material.
