Abstract: The glass panel unit includes a first glass panel, a second glass panel, a seal, an evacuated space, and a spacer. The second glass panel is placed opposite the first glass panel. The seal with a frame shape hermetically bonds the first glass panel and the second glass panel to each other. The evacuated space is enclosed by the first glass panel, the second glass panel, and the seal. The spacer is placed between the first glass panel and the second glass panel. The spacer is a stack of two or more films. At least one film of the two or more films contains a polymer having a viscoelastic coefficient at 400° C. larger than 500 MPa.

Abstract: A thermal conductivity changing unit includes: at least one thermal conductivity changing device; and a gas barrier film having an accommodation space which accommodates the at least one thermal conductivity changing device. Each of the at least one thermal conductivity changing device includes a pair of panels, a spacer, and a switching mechanism. The spacer forms a space between the pair of panels. The switching mechanism is disposed in the space to switch heat transferability between the pair of panels. The gas barrier film is configured to hermetically close an entirety of the accommodation space including the space in a depressurized state.

Abstract: A glass panel unit includes a first panel, a second panel, a frame body and a reduced pressure space. The reduced pressure space is surrounded with the first panel, the second panel and the frame body other than an exhaust path capable of exhausting gas to an outside, and sealed in a reduced pressure state. In a state where the inner space has been formed, the seal includes a protruding portion positioned outside of edges of a first surface of a first substrate and a second surface of a second substrate. The protruding portion has a length, along the thickness directions of the first substrate and the second substrate, longer than a prescribed interval.

Abstract: Disclosed herein is a glass panel unit including: a first panel including at least a first glass plate; a second panel arranged to face the first panel and including at least a second glass plate; a frame member formed in a shape of a frame corresponding in shape to respective peripheral portions which extend along edges of the first panel and the second panel, and bonded to the peripheral portions; and at least one spacer provided in a vacuum space between the first panel and the second panel. The at least one spacer contains a polyimide. The polyimide has an absorption edge at which an absorption index decreases in an optical absorption spectrum ranging from an ultraviolet ray to visible radiation. The absorption edge is equal to or less than 400 nm.

Abstract: The objective is to propose a production method of multiple panes which can be simple and nevertheless produce a multiple pane in its finished state which does not include any undesired protrusion from an external surface of a glass panel. The production method includes: hermetically bonding, with a sealing member, peripheries of paired glass panels disposed facing each other at a predetermined distance to form a space to be hermetically enclosed between the glass panels; evacuating air from the space through an outlet to make the space be in a reduced pressure state; subsequently dividing the space by a region forming member disposed inside the space to form a partial region which do not include the outlet; and subsequently cutting out the partial regions by cutting the pair of glass panels.

Abstract: The panel unit includes a first panel, a second panel facing the first panel with a space provided therebetween the first panel and the second panel, a partition separating the space from a surrounding space, and a switching mechanism. The switching mechanism is located in the space for allowing a change in thermal conductivity between the first panel and the second panel. The switching mechanism includes at least one connector which is thermally conductive, and is switchable between a first state in which the at least one connector is out of contact with the first panel or the second panel and a second state in which the at least one connector is in contact with both the first panel and the second panel.
