Each SIGA product has its unique function. The air and wind tight building envelope can be compared with clothing of people. In cold and damp weather several layers of clothing provide comfortable protection. Underwear carries moisture (sweat) away from skin which corresponds to the airtight building shell (=vapor control layer). A sweater protects from cold (=insulation). But in cold and windy weather, this sweater is not sufficient. You additionally need a windbraker (=facade membrane or breathable membrane). When this jacket is open, cold wind and moist air enter the sweater and you feel cold. If it is closed, which corresponds to the windtight building envelope, wind and weather are kept out and the body remains comfortably warm.
