Improved provision of airtightness in windows, characterized in that according to the same between a profile and the lower flashing of the framing is captured an elastic strip that extends, inward, contouring said profile to finish all along its free edge in a flange, which in the closing of the window is elastically deformed by the lower edge of the leaf, thus determining a perfect, hermetic seal throughout its entire length; said leaf has a stepped configuration that in conjunction with that of the window profile defines an air chamber communicated with the outside by a narrowing, delimiter of the passage of air, which is then expanded in said chamber, also acting on the elastic strip, so that it collaborates in the hermetic action of it.
