Double-skin façade element

A double-skin façade element, comprising:

• a planar outer glazing element and a planar inner glazing element which are held at a distance from one another in a thermally insulated surrounding frame profile;
• at least one pressure equalization device which is in air-conducting connection with an outside atmosphere and with a façade intermediate space which is provided between the outer glazing element and the inner glazing element;
• at least one drying device fillable with desiccant which is either arranged in the façade intermediate space or is integrated into the surrounding frame profile and exchanges air with the façade intermediate space,
• wherein:
• the double-skin façade element further comprises means for reducing vapor diffusion, wherein the means for reducing vapor diffusion comprise wet glazing and at least one insulation web for thermal separation in the thermally insulated surrounding frame profile that is at least one of made of a plastic with high vapor tightness or with a coating material with high vapor tightness;
• the pressure equalization device and the drying device are positioned and dimensioned such that the devices do not extend into a transparent region of the façade element;
• and
• the at least one drying device is configured to allow the desiccant to be replaced and comprises a replacement opening configured to allow the desiccant to be replaced from a room side.

• at least one pressure equalization device which is in air-conducting connection with an outside atmosphere and with a façade intermediate space which is provided between the outer glazing element and the inner glazing element, and an air routing device,
• wherein:
• pressure loss of air flow during pressure equalization is determinable and adjustable by at least one of a length, cross-sectional dimensions of the air routing device or the number of deflections of the air flow passing through the air routing device;
• at least one drying device fillable with a desiccant bed which is integrated into the surrounding frame profile,
• the at least one drying device comprises at least one first opening which is in air-conducting connection with the façade intermediate space;
• the at least one pressure equalization device and the at least one drying device are positioned and dimensioned such that the pressure equalization and drying devices do not extend into a transparent region of the façade element, and
• the at least one drying device is configured to allow the desiccant to be replaced and comprises a replacement opening configured to allow the desiccant to be replaced from a room side.
