Rahma, There are two options that you could consider. If the greenhouse covering is transparent or translucent, I would suggest that you define the material in Lawrence Berkeley National Lab's Window5 software and import the resulting window into Type56. If you do not want to worry about visible light transmittance, simply define the material as a purely resistive (massless) layer. Kind regards, David
