A spacer for a multi-pane insulating glazing unit includes a spacer body made from a first material with first and second hollow desiccant chambers extending in a longitudinal direction and a longitudinal groove between the first and second chambers open to a first side of the spacer for holding an intermediate pane of the glazing unit, the groove being delimited in a width direction by first and second side walls and having a bottom wall, and the spacer body having a gas barrier on a second side opposite the first side. The first side wall and/or the second side wall and/or the bottom wall of the groove include at least two electrically conductive portions electrically isolated from each other and configured to make electrical contact with at least one electrical contact of the intermediate pane.

Examples of the present disclosure provide an overhead door panel. The overhead door panel includes a pair of parallel glass panes, a metal frame with parallel lateral stiles oriented perpendicular to the pair of parallel glass panes, a first seal system located at a first lateral stile, and a second seal system located at a second lateral stile, wherein the first seal system and the second seal system engage with at least one glass pane of the pair of parallel glass panes and a lateral stile of the parallel lateral stiles of the metal frame such that the first seal system and the second seal system are between the at least one glass pane and the lateral stile.

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.

A flexible spacer body has two opposing faces adapted to engage the inner surfaces of glazing structures to define an insulating glazing unit. The spacer body may be desiccated polymeric foam such as a silicone foam rubber or EPDM. An adhesive capable of bonding the spacer body to the glazing structure is carried by both of the faces. The adhesive may be from about 0.050 mm to about 1.524 mm thick. The adhesive material also has the properties of low argon gas and low moisture permeability. The adhesive comprises polymers where butyl rubber and/or polyisobutylene polymers together make up the majority of the polymers. The adhesive may also comprise other materials as needed to make it pressure sensitive and to impart a water resistant bond to glass glazing structures. The space assembly may include additional materials to secure the adhesive to the spacer body.

A spacer for multipane insulating glazing units includes a polymeric main body having two pane contact surfaces running parallel to one another, a glazing interior surface and, an adhesive bonding surface. The pane contact surfaces, and the adhesive bonding surface are connected directly or via connection surfaces. The spacer also includes an insulation film, which is applied on the adhesive bonding surface.

A spacer for insulated glazing units having at least one polymeric main body with a wall thickness d having a first pane contact surface and a second pane contact surface running parallel thereto, one first glazing interior surface, one second glazing interior surface, one outer surface, one first hollow chamber, and one second hollow chamber. A groove for receiving a pane runs parallel to the first pane contact surface and the second pane contact surface between the first glazing interior surface and the second glazing interior surface. The first hollow chamber adjoins the first glazing interior surface and the second hollow chamber adjoins the second glazing interior surface. The lateral flanks of the groove are formed by the walls of the first hollow chamber and the second hollow chamber, and the wall thickness d′ in the region of the lateral flanks is less than the wall thickness d of the polymeric main body.

A spacer for insulating glass units, includes a U-shaped main body extending in the longitudinal direction including a first metallic side section, a second metallic side section arranged parallel thereto, a polymeric connecting piece extending in the transverse direction, which connects the two metallic side sections and forms the lower limit of the main body, and an intermediate space arranged above the polymeric connecting piece between the metallic side sections. The first and second metallic side sections each include a side wall for connecting to a glass pane and a retaining arm, which protrudes into the intermediate space, and the retaining arm forms an assembly groove with the side wall, which groove runs substantially parallel to the side wall. The polymeric connecting piece is U-shaped and its two legs are inserted into the assembly grooves of the two metallic side sections.

A spacer is provided that is shapable into a spacer frame, and during manufacture of an insulating glass unit, can be mounted on the glass panes. The spacer is formed having an inner surface, an outer surface and two lateral surfaces extending at either side of the spacer from the inner surface to the outer surface, and comprises a profiled body. The profiled body comprises two mutually spaced lateral faces running parallel to its longitudinal direction and a base body that extends between the lateral faces and has an outer and an inner face. The profiled body comprises at least in one part of its volume a quantity of particulate desiccant that is embedded in a plastics material. The spacer is coilable about an axis, perpendicularly to the lateral surfaces, and takes a flexurally rigid form in a plane perpendicular to the lateral surfaces.

A spacer profile for an insulating glazing unit for maintaining a space between glazing panes includes a profile body formed from a first heat insulating material that has, viewed in a cross section perpendicular to a longitudinal direction, outer side walls extending in a height direction and that has a distance in a transverse direction smaller than a first width, each side wall having an inner protrusion protruding towards the opposite side wall into a recess which is open to the inner side, and a diffusion barrier film made from a second material and firmly bonded with the profile body and, viewed in the cross section perpendicular to the longitudinal direction, extending over the profile body on the outer side of the spacer profile and continuous thereto in the height direction on the outside of the side walls and/or in the same to a second height and into the protrusions.

A switchable glazing unit comprising a glazing panel spaced apart from a pane of glazing material by a perimeter seal is described. The glazing panel comprises first and second glass sheets. A first electrode layer is on a first major surface of the first glass sheet and a second electrode layer is on a first major surface of the second glass sheet. A layer of liquid crystal material is between the first electrode layer and the second electrode layer. When no voltage is applied to the first and second electrode layers, the liquid crystal layer has a first opacity, and upon applying a suitable voltage between the first and second electrode layers, the liquid crystal layer has a second opacity different to the first opacity. Methods of making such a switchable glazing unit are also described.
