Rockidan SD-Z-PAM Calculater

Water Vapor Diffusion of e.g. paints is rated in different ways according to different formulas. This sometimes makes it difficult to compare the W.V.D. of two different products. The Rockidan Sd-calculator makes it easy to find the corresponding values, no matter what value (Sd / Z / PAM) you may have or need. Move the slider of one value, and see the corresponding values in the other systems.
