1. A means for the dehumidification, perspiration, ventilation or impermeabilization of walls, floors and/or ceilings by the use of a double fretted membrane (M1, M2), the shape of which defines longitudinal channels (C), characterized in that there is provided a peripheral section (1) having a tubular body 4 from which two pairs of longitudinal ribs (2, 3) perpendicular to each other and extending all over the length of section (1) project, each pair of ribs (2, 3) being able to receive a peripheral edge of the double membrane (M1, M2), and characterized in that in order to dehumidify and/or to cause the surface of a building to which the double membrane (M1, M2) is applied to perspire, the section (1) is provided with side holes (7) longitudinally distributed between each pair (2, 3) of the ribs, characterized in that once the double fretted membrane (M1, M2) is inserted between the pairs of ribs (2, 3), said side holes (7) are positioned at channels (C) of double membrane (M1, M2) so that the humidity and/or any gas in said channels enters tubular body (4) of section (1) through holes (7) to come then out to the outside through a piping or conduit (5) arranged to connect at least one of the two ends of tubular body (4) of section (1) to the outside, thus providing a ventilation of the building directly to the outside.
