Abstract: An insulating glazing includes two glass sheets spaced apart by an air- or gas-filled cavity, a spacer arranged at a periphery of the glass sheets and that keeps the glass sheets spaced apart, a transparent spacer made of transparent plastic and placed on at least one of the sides of the glazing, and a first leaktight barrier that is leaktight to water, formed by a structural seal, a material of which is watertight, and a second leaktight barrier that is leaktight to gases and to water vapor, the leaktight barriers being made of transparent material, wherein the spacer includes on at least one of its internal and external faces, the internal and external faces being respectively facing and on the opposite side from the gas-filled cavity, a coating which is thin and constitutes the second transparent barrier, the coating and the transparent spacer forming a single assembly.

Abstract: A process for manufacturing a gas-filled multiple glazing unit including at least two glass sheets, the process including a preassembly step in which each glass sheet is positioned inclined at an angle strictly greater than 0° and less than or equal to 10° to the adjacent glass sheet, so as to form at least one cavity, each cavity being completely closed on one of its sides; a step of partially blocking at least one of the sides of each cavity; a step of filling each cavity with gas via an injection side of the cavity; and a step of pressing the glass sheets. One or more cavities of a multiple glazing unit can be filled while reducing the amount of gas used and the filling times.

Abstract: A gripping device is configured to hold an insulating glazing subassembly including a spacer frame and at least one central glass sheet received in an internal peripheral groove of the spacer frame. The gripping device includes, on the one hand, members for gripping the spacer frame and, on the other hand, members for gripping the central glass sheet so as to ensure an independent gripping of the spacer frame and of the central glass sheet while allowing a relative movement of one with respect to the other.

Abstract: A process includes the assembling of an insulating glazing subassembly which includes a spacer frame and at least one central glass sheet, the spacer frame being formed of four profiles angularly assembled at their ends, where each profile has a groove for receiving one edge of the central glass sheet. The assembling of the insulating glazing subassembly includes successive steps wherein: the four edges of the central glass sheet are inserted into the grooves of the four profiles; the ends of the profiles are assembled by welding at each corner of the spacer frame without an alignment bracket, using the edges of the central glass sheet inserted in the grooves of the profiles as a frame of reference for guiding the profiles at each corner of the spacer frame into a configuration where their end faces are aligned by superposition in one and the same plane.

Abstract: A method of manufacturing a gas-filled triple glazing, including: a pre-assembly during which three sheets of glass are positioned beside one another, at least one of the sheets of glass including a spacer, each sheet of glass being positioned inclined by an angle between 0° and 10° with respect to an adjacent sheet of glass, to form two cavities, each of the cavities being between two adjacent sheets of glass; filling the two cavities by injecting gas into the two cavities at a same time using nozzles; pressing the sheets of glass against one another to seal the triple glazing. The method allows triple glazing to be manufactured quickly.
