| 摘要 | Water vapor control, which is arranged facing the inside of a building, comprising a first layer having a water vapor diffusion resistance (sd-value) of 1-5 meters diffusion-equivalent air space width, measured at a relative humidity of an atmosphere surrounding the layer of 30-50%, and having a Sd-value of <1 meters diffusion-equivalent air space width, measured at a relative humidity of 60-80%, and a second layer having a Sd-value of >0.6 meters diffusion-equivalent air space width, measured at a relative humidity of 80-100%. | ||

| 主权项 | 1. A multi-layer water vapour control film comprising a first film layer and a second film layer, wherein the first film layer is comprised of a polyamide film having a water vapour diffusion resistance (Sd-value) of 1-5 meters diffusion-equivalent air space width, measured at a relative humidity of an atmosphere surrounding the layer of 30-50%, and a Sd-value of <1 meters diffusion-equivalent air space width, measured at a relative humidity of 60-80%, and wherein the second film layer is comprised of a polyester film or copolyester film having a Sd-value of >0.2 meters diffusion-equivalent air space width, measured at a relative humidity of 80-100%. | ||
