A metal door frame for a door opening comprising at least one first door frame segment for upper or side portions of the door opening, the at least one first door frame segment having a first molding flange, a first jamb face adjacent to the molding flange, and a first stop flange adjacent to the jamb face. The metal door frame includes at least one second door frame segment for upper and side portions of the door opening, the at least one second door frame segment having a second molding flange, a second jamb face adjacent to the molding flange, a second stop flange adjacent to the jamb face, a second stop face adjacent to the stop flange, and a third stop flange adjacent to the stop face. The metal door frame includes a thermally insulative layer between the first door frame segment and the second door frame segment.

A composite structure has a pair of parallel aluminum extrusions bridged by a polymer cap and defining a U-shape hollow. The hollow is filled with an expandable foam that adheres to and mechanically interdigitates with the extrusions, which have channels for receiving insertion legs of the extrusions and have extensions, which the foam encapsulates. End caps may be used to further delimit the hollow. The caps and the foam have a thermal conductivity less than that of the extrusions, providing a thermal break. An upper cap may be used and may incorporate features to compensate for the foam expansion. Excess foam may be trimmed. A forked tool may be used to hold the extrusions during joining.

A window system has a window frame that surrounds a window unit. The window frame has a glazing leg with an outer wall and an inner wall. The inner wall forms a J-shaped stem, which forms a J-shaped channel between the inner wall and the outer wall. A first gasket engages with the outer wall, and is maintained in compression between the outer wall and the window unit. Likewise, a second gasket engages with the inner wall, and is maintained in compression between the inner wall and the window unit.

The present disclosure relates to an insulated frame section. The frame section comprises an elongate interior frame member, an elongate exterior frame member and an elongate insulation element connected to the interior frame member and to the exterior frame member. The insulation element prevents any direct physical contact between the interior and exterior frame members. A refrigerator door system having a door and a door frame constructed from such insulated frame sections is also disclosed.

A metal door frame for a door opening comprising at least one first door frame segment for upper or side portions of the door opening, the at least one first door frame segment having a first molding flange, a first jamb face adjacent to the molding flange, and a first stop flange adjacent to the jamb face.

The metal door frame includes a thermally insulative layer between the first door frame segment and the second door frame segment.

The invention features a refrigerator cabinet door frame. The frame includes a thermally conductive outer frame, a thermally insulating inner frame member, and a sealing plate. The outer frame member includes a forward end having an outer surface that is disposed outside of a refrigerated cabinet with the frame mounted, and a rearward end defining a joint. The inner frame member includes a first end retained in the joint, and a second end. The sealing plate includes a first edge coupled to the outer frame member at the rearward end, forward of the joint, a second edge supported by the second end of the inner frame member, and a thermally conductive sealing surface. The first edge of the sealing plate is coupled to the outer frame member such that the sealing surface and the outer surface of the outer frame member together form a continuous heat transfer path.

A composite aluminum alloy profile and a preparation method therefor. The composite aluminum alloy profile includes an outer decorative profile, a polyurethane elastomer structural adhesive, and an inner frame profile. The inner frame profile is an integral component of alkali-free glass fibers and polyurethane resin formed by one-time extrusion, and the inner frame profile comprises one upper closed cavity and one lower closed cavity for a total of two cavities and a reinforced heat insulation rib plate between the upper closed cavity and the lower closed cavity; and the outer decorative profile is connected to the inner frame profile through the polyurethane elastomer structural adhesive. The preparation method includes: preparing glass fibers and polyurethane materials of components A and B into a glass fiber resin reinforced profile by a compound strip-threading and injection machine, adhering the inner frame profile to the outer decorative profile through the polyurethane elastomer structural adhesive, and rolling the same. The profile has the features of heat and sound insulation and is easy to produce.
