Zusammenfassung: | The invention refers to a sealing system for joints of joinery construction elements, especially windows and exit doors, which comprises two front layers, which constitute the material that sets the system and seals the insulation material. One of the front layers being the internal layer on the inside of the construction element and the other front layer being the external layer on the outside of the construction element. The external front layer contains materials such that the equivalent diffusion resistance factor (Sd) is not greater than 2 m, while the intemal front layer contains materials such that the equivalent diffusion resistance factor (Sd) is equal to or greater than 30 m, the internal front layer contains low-permeability components and the external front layer contains vapour-permeable components. |
