An insulating glazing includes two glass sheets that are spaced apart by an air- or gas-filled cavity, a spacer arranged at periphery of the glass sheets and that keeps the glass sheets spaced apart, the spacer being transparent and placed on one of the sides of the glazing, and a first barrier that is leaktight to water, formed by a structural seal, the material of which is watertight, and a second barrier that is leaktight to gases and to water vapor, the first and second barriers associated to the transparent spacer being made of transparent material, wherein the second barrier that is leaktight to gases and to water vapor and made of transparent material is arranged at an interface between the glass sheets and the transparent spacer on an internal side of the glazing, the structural seal also at the interface being positioned abutted and aligned with the second barrier.

Insulating glazing unit, in particular for a climate chamber

An insulating glazing includes two glass sheets spaced apart by at least one air- or gas-filled cavity, at least one transparent spacer made of glass, which is arranged at a periphery of the glass sheets and which keeps the two glass sheets spaced apart, and a transparent fastening system to fasten by adhesive bonding, which fastens the spacer to each glass sheet via two opposite fastening faces of the spacer, wherein the spacer made of glass is obtained by the cutting of glass sheet in a raw state, and is joined to the glass sheets directly in the raw state, and wherein the fastening system to fasten by adhesive bonding consist of a transparent material having been placed at an external junction of the spacer and of the glass sheets and having flowed into asperities of the glass of the fastening faces of the spacer.

Insulating glazing with glass spacer, notably for climate-controlled unit

An insulating glazing includes at least two substantially parallel glass sheets, which are spaced apart by at least one air- or gas-filled cavity forming a cavity internal to the glazing, a spacer, which is arranged at a periphery of the glass sheets and which keeps the two glass sheets spaced apart, and an adhesive bonding system arranged to fasten the spacer to each glass sheet via two of opposite fastening faces of the spacer, wherein the spacer includes, at least for one side of the glazing, a mirror-function reflective surface on an internal face of the spacer facing the internal cavity of the glazing.

Insulating glazing, in particular for a temperature-controlled piece of furniture

An insulating glass element suitable for a refrigeration cabinet. The insulating glass element includes a first pane and a second pane spaced at a distance from the first pane. The first pane has two opposite parallel horizontal edges and two opposite parallel vertical edges. The second pane has two opposite parallel horizontal edges and two opposite parallel vertical edges. According to one aspect, two horizontal spacers are arranged between the first pane and the second pane. According to another aspect, two vertically arranged flat profiles are secured to the vertical edges of the first pane and to the vertical edges of the second pane. According to yet another aspect, the spacers and the flat profiles enclose an inner interpane space between the first pane and the second pane, and one of the two flat profiles is transparent.

Insulating glass element for a refrigeration cabinet

An insulating glazing includes two glass sheets spaced apart by an air- or gas-filled cavity, at least one spacer arranged at a periphery of the glass sheets and that keeps the glass sheets spaced apart, one of the spacers being transparent, made of transparent plastic and placed on 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.

An insulating glass unit suitable for a refrigeration unit is presented. The insulating glass unit includes a first pane, a second pane spaced at a distance from the first pane, a peripheral spacer frame between the first pane and the second pane, and an inner interpane space. According to one aspect, the spacer frame includes four hollow-profile polymeric spacers, which are secured between the first pane and the second pane along one of the four sides of the insulating glass. According to another aspect, the two first hollow-profile polymeric spacers are arranged along two opposing first sides of the insulating glass unit and the two second hollow-profile polymeric spacers are arranged along two opposing second sides of the insulating glass unit. According to yet another aspect, the first polymeric hollow-profile spacers contain 5% to 50% and the second polymeric hollow-profile spacers contain 0% to 0.5% reinforcement fibers.
