Door assemblies with insulated glazing unit venting

A method of venting an insulated glazing unit positioned within a door, comprising the steps of:

• a. providing a door comprising a peripheral frame, first and second door skins secured to opposed sides of the door frame, an insulated glazing unit (IGU) sealed, directly or indirectly, to the first and second door skins, and a door core component positioned within a door cavity between the first and second door skins in contact with the IGU;
• b. forming a first opening in the periphery of the IGU, and a second opening extending through the peripheral frame, the second opening being in communication with the first opening and opened to the atmosphere outside the door;
• c. providing a capillary tube having a first end and a second end, and a vent tube having a first end and a second end;
• and
• d. connecting the first end of the capillary tube to the first opening, the second end of the capillary tube to the first end of the vent tube, and the second end of the vent tube to the second opening,
• wherein the capillary tube and the vent tube form a gas passage conduit passing through at least a portion of the door core component, and having a first end communicating with the substantially sealed IGU cavity through the first opening and a second end communicating with the atmosphere outside of the door assembly through the second opening.
