A fluid exchanging system and method for use in exchanging fluids in insulating glass units (IGUs). The fluid exchanging system includes an articulating arm having a plurality of members and arms to allow movement about multiple axes defined by the articulating arm, an optical sensor system, coupled to the articulating arm, for identifying an opening in a spacer frame of an IGU, and a fluid exchanging apparatus releasably couplable to the articulating arm. The fluid exchanging apparatus also includes a fluid exchanging head for evacuating atmospheric air from the IGU and dispensing fluid into the IGU.

A door includes a first skin, a second skin, two stiles, a core, and a gas permeable membrane. The first skin provides a first outer door surface. The second skin provides a second outer door surface. The two stiles are disposed at least partially between the first skin and the second skin. At least one stile defines a vent therein. The core comprises a foam material and is disposed between the first skin and the second skin. The gas permeable membrane, which is permeable to gas but not to the precursors of a foam material, is disposed on the at least one stile covering the vent. The gas permeable membrane contacts the foam material in the core, and separate the foam material in the core from the vent.

A manufacturing method of a glass panel unit of the present invention includes a bonding step, a pressure reduction step, and a sealing step. In the bonding step, a first substrate and a second substrate are hermetically bonded together with a seal having a frame shape. In the pressure reduction step, a pressure in an inside space formed between the first substrate and the second substrate is reduced through an exhaust port. In the sealing step, sealant disposed between the first substrate and the second substrate is deformed, and the sealant thus deformed seals an opening of the exhaust port.

A multi-layer laminate includes a glass panel unit, an intermediate film, and a transparent plate. The transparent plate is assembled to the glass panel unit via the intermediate film. The glass panel unit includes a first and second glass panel, and an evacuated space. The evacuated space is interposed between the first and second glass panel. A method for manufacturing the multi-layer laminate includes a step. The step includes exhausting a gas from a bag, loaded with the glass panel unit, the intermediate film, and the transparent plate, to cause the bag to shrink and thereby assembling, using the bag thus shrunk, the glass panel unit and the transparent plate via the intermediate film. The step includes raising a pressure inside the bag from a pressure at an initial stage of heating while increasing a temperature of the intermediate film to a predetermined temperature at which the intermediate film softens.

A glass unit including a spacer, a front glass pane attached to a front side of the spacer, a back glass pane attached to a back side of the spacer, and a pressure equalization conduit defined by and within the spacer, wherein the pressure equalization conduit has a first end and a second end, wherein the pressure equalization conduit contains a desiccant and is in fluid communication with an exterior of the glass unit at a first end port adjacent to the first end and with an interior space of the glass unit at a second end port adjacent to the second end. The glass unit may further include one or more intermediate layers contained within the interior space and one or more floating suspension systems for supporting the intermediate layers.

The glass panel unit includes a first glass panel, a second glass panel, a seal, an evacuated space, and at least one 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 at least one spacer is placed between the first glass panel and the second glass panel. The at least one spacer has a height H1 smaller than a height H2 of the seal between the first glass panel and the second glass panel.

A glass panel unit includes: a first glass pane; a second glass pane facing the first glass pane; a frame member; an evacuated space; and a gas adsorbent. The frame member hermetically bonds the first glass pane and the second glass pane. The evacuated space is surrounded with the first glass pane, the second glass pane, and the frame member. The gas adsorbent is placed in the evacuated space. The gas adsorbent contains a getter material. The getter material contains a plurality of particles of a zeolite crystal. At least one particle accounting for a half or more of a total weight of the plurality of particles has a particle size equal to or greater than 200 nm. An activable temperature of the at least one particle is equal to or lower than 400° C.

Various embodiments herein relate to methods, structures, tools, installation systems, etc. for retrofitting a new electrochromic window in a pre-existing window recess. In many cases, the new electrochromic window is installed parallel to a lite of a pre-existing window, with the resulting structure including the new electrochromic window, the pre-existing window, and a pocket that forms between them. Installation of a new electrochromic window in tandem with a pre-existing window results in many benefits including improved insulation (e.g., due to the presence of the additional air pocket(s) and lite(s)), improved climate control (e.g., due to the ability to control the amount of sunlight entering the building via the electrochromic window), and enhanced aes thetics.
