Against a room-limiting building surface are fitted ventilating intermediate space-producing components, and such intermediate spaces are connected to the outer atmosphere to conduct away air contg. radon. Such components comprise relatively thin, prefabricated corrugated material sheets consisting of at least one flat liner layer turned away from the building surface and at least one wave-form fluting layer, the channels of which form long, parallel air flow paths along the building surface to conduct away the air contg. randon. - The corrugated material consists of cardboard, although it is preferable for plastic material to be used which has the same formation as cardboard. On one side of the air flow paths located inside the room in the building is a diffusion-tight sheet or layer form of plastic sheeting. |
