A heat-insulating window panel includes: a light-transmissive member having light transmissivity; and a panel member including an outdoor substrate that supports the light-transmissive member from an outdoor side via a first elastic body, an indoor substrate that supports the light-transmissive member from an indoor side via a second elastic body without being in contact with the outdoor substrate, and a heat-insulating material disposed between the outdoor substrate and the indoor substrate, and even when a force is applied to one of the outdoor substrate and the indoor substrate in a direction away from the other to move the one in a separating direction, the outdoor substrate and the indoor substrate have a hooking margin for hooking the one on the other.

A composite profile for windows, fixed glazing, faades, doors or glass roofs. A metal profile is produced by shaping, in particular by roll-forming, from a sheet metal material and that has a profile cross section that forms a groove and a web, the web being formed by profile portions that are on top of one another at least in portions and transition into profile portions that define the groove. The composite profile further comprises an integral or multi-part insulating profile received in the groove of the metal profile in portions and is non-positively and/or positively connected to the metal profile. The insulating profile and/or a further profile received in the groove of the metal profile engages/engage in pockets of the metal profile that are open towards the groove and are arranged on either side of the web.

A spacer, window assembly, method of manufacturing a window assembly, and method of manufacturing a spacer is described herein involving window assemblies having three sheets of material, which will be referred to as a triple pane assembly. Two interior spaces are defined within the window assembly: a first air space between the first sheet and intermediary sheet and a second air space between the second sheet and the intermediary sheet.

A thermal barrier for sealing an air gap opening in a sliding door structure, a sliding door structure and thermal barrier combination, and a method for sealing such an air gap opening. The thermal barrier has an elongate base sealing member and an elongate raised sealing member, both formed of resiliently compressible, insulative material, fixed together over the lengths thereof. An insertion portion of the base sealing member extends beyond the raised sealing member and is inserted into the air gap opening between a trailing edge of a first, sliding door and the surface of a second door of the sliding door structure. A plurality of retention members, each with a suction cup portion and a protuberating portion, secure the thermal barrier in position relative to the sliding door structure with the insertion portion of the base sealing member inserted into the air gap opening.
