The purpouse of this work is to introduce the new patented Hygrobrid technology for moisture variable control layers. The new variable membrane has directional permeability capabilities. The tecnology ensures better safety for every construction even when the moisture levels are high during construction phase and also when the structure is subjected to extreme moisture during use. The technology minimises moisture development within the structure and maximises moisture transport out of the structure. This work is presenting the performance difference between first, second and third generation moisture variable membranes based on the computer simulation.
