A method of assembling a portal can include obtaining a stile, wherein the stile can include a first stile and a second stile; arranging a thermal strut and insulative bar between the first stile and the second stile, wherein the insulative bar can define a lock groove; arranging a lock assembly within the lock groove, wherein the lock assembly can include a fastening plate rotatably coupled to the lock assembly; and coupling the lock assembly to the stile by rotating the fastening plate and, thereafter, engaging fasteners to provide friction between the fastening plate and the insulative bar.

A composite architectural frame section with subcomponents that meet functional, strength and thermal isolation requirements is assembled using knurling and crimping operations as joining procedures. When properly designed the knurling and subcomponent geometries with proper crimping operations result in an optimal shearing strength between critical subcomponents, thus maximizing the structural performance aspect of the frame section. Various embodiments of this design address requirements for subcomponent features such as: hammer and anvil tips, orientation of knurled and crimped surfaces, design of the knurling wheel components, and the introduction of alternate surface topographies to additional regions of these contacting frame subcomponents. These embodiments serve to maximize the portion of available interface contact surfaces and their friction that can bear shearing forces and, thus, add to the overall shear strength of the frame section.

Provided herein are thermal break structural members for use in fenestration assembly products. In some embodiments, the thermal break structural member is monolithic with an infill retainer, being designed to bear a structural load while maintaining the overall integrity and thermal performance of the conjoint fenestration unit.

An insulated fenestration system includes a frame comprising a first bracket, the first bracket defining a sealing slot; a pane assembly assembled with the frame, the pane assembly comprising a first pane; a bracket gap defined between the first bracket and the first pane; and a first seal engaging the sealing slot, the first seal extending across the bracket gap and abutting the first pane.

A profile for a fenestration system includes first and second members, and a thermal break extending between the first and second members. The thermal break is coupled to the first member at a thermal break interconnection that includes a tab extending laterally from a body, the tab including a head extending from the body and a stem extending from the head. A channel is defined between upper and lower flanges of the first member and provides a first chamber sized to receive the head, and a second chamber extending from the first chamber and sized to receive the stem. The head is larger than the stem, and the first chamber is larger than the second chamber. The thermal break is temporarily secured to the channel by advancing the tab into the channel, and permanently secured to the channel by crimping the flanges against the tab.

A splicing pipe for installing a door or window includes a first frame profile, a second frame profile, a heat insulation strip and at least two fasteners. A first clamping groove is formed on each of two sides of the first frame profile, and a second clamping groove is formed on each of two sides of the second frame profile. The first clamping groove and the second clamping groove are both used to connect to the door or window having glass. At least one of the first frame profile and the second frame profile on the same side is provided with an installation groove, and the fastener is inserted into the installation groove. The splicing pipe provided has the advantages of simple splicing operation and easy implementation, which can not only improve the splicing speed, but also guarantee the performance of the doors or windows after being spliced.

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.

An insulating strip (3) connects profiles (2) of a composite profile (1) for doors, windows or faade elements. At least one of the profiles has a roll-in groove (6) and is composed of a first metal material. The insulating strip (3) includes a strip body (4) composed of an insulating material and extending in a longitudinal direction (z). A roll-in head (5) is formed at a longitudinal edge of the strip body (4). The roll-in head (5) has a cross-sectional shape in a plane (x-y) perpendicular to the longitudinal direction (z) suitable for insertion into the roll-in groove (6). A metal sheet (13) having surface variations (17; 18) covers at least a portion of a surface (10, 11, 12) of the roll-in head (5). At least a portion of the sheet (13) is composed of a second metal material having a tensile strength of 300 N/mm.sup.2 or more.

An insulated fenestration system includes a frame, a pane assembly assembled with the frame, the pane assembly including a first pane, and a muntin bar attached to the first pane. The muntin bar defines an angled end abutting and matching an angle of the sloped front surface. The frame extends around a perimeter of the first pane so as to include a top portion, a bottom portion, a left portion, and a right portion. A vertical muntin bar can extend between and to the top portion and the bottom portion and is spaced apart from the left portion and the right portion. A horizontal muntin bar can extend between and to the left portion and the right portion and is spaced apart from the top portion and the bottom portion. The muntin bar subdivides the first pane into a plurality of simulated lites.

A window, door, or facade element includes an outer frame composed of out frame bars and a leaf frame composed of leaf frame bars. One or more of the outer frame bars and/or of the leaf frame bars has/have at least the following features: a base profile, on which two fastening grooves that are open in the same direction are formed for fixing a corresponding fastener of a fitting arrangement, which bridges the intermediate space between the fastening grooves. The two fastening grooves have at least one latch for at least one counterpart latch, which can be attached without tools, of a fitting part arrangement. The fitting arrangement has a functional fitting on a fitting plate and at least one support element for supporting the fitting. The support element is designed for direct or indirect latching in the fastening grooves by means of the counterpart latch.
