A device for the dehumidification, perspiration, ventilation or impermeabilization of walls, floors and/or ceilings by the use of a double fretted membrane of the known type, the shape of which defines longitudinal channels, characterized in that there is provided a peripheral section having a tubular body from which two pairs of longitudinal ribs perpendicular to each other and extending all over the length of the section project. Each pair of ribs is able to receive a peripheral edge of the double membrane.

The invention claimed is: 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. 2. The means according to claim 1, characterized in that first membrane (M1) is laid by a restricted amount of glue to keep free the recesses of the fret directed to the building and providing channels (C). 3. The means according to claim 1, characterized in that to provide the waterproofing of the building member to which the double fretted membrane (M1, M2) is applied, another peripheral section (1′) without side holes is provided to which the double fretted membrane (M1, M2) is secured by glue or a sealing means so as to fill any room between peripheral edges of channels (C) of double membrane (M1, M2) and the inside of the pairs of ribs (2, 3) of section (1′) between which said double membrane is fitted. 4. The means according to claim 1, characterized in that connecting pipe (6) is perforated at side holes (7) of section (1). 5. The means according to claim 1, characterized in that first membrane (M1) is laid by a restricted amount of glue to keep free the recesses of the fret directed to the building and providing channels (C). 6. The means according to claim 1, characterized in that connecting pipe (6) is perforated at side holes (7) of section (1). 7. 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 to connect two adjacent sections (1) upon laying down, a length of pipe (6) running along the ends of sections (1) is inserted therein, thus restoring the continuity of tubular bodies (4). 8. The means according to claim 7, characterized in that connecting pipe (6) on which the two sections (1) slide has lower outside dimensions than the inside dimensions of tubular body (4) of sections (1) so that such pipe is fitted into said sections (1) by sliding coupling. 9. The means according to claim 8, characterized in that connecting pipe (6) is perforated at side holes (7) of section (1). 10. The means according to claim 7, characterized in that connecting pipe (6) on which the two sections (1) slide has lower outside dimensions than the inside dimensions of tubular body (4) of sections (1) so that such pipe is fitted into said sections (1) by sliding coupling. 11. The means according to claim 7, characterized in that connecting pipe (6) is perforated at side holes (7) of section (1). 12. 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 to guarantee a firm fastening of sections (1), a connecting pipe (6) is glued to the sections. 13. The means according to claim 12, characterized in that connecting pipe (6) is perforated at side holes (7) of section (1).
