Example aspects of a simulated steel fenestration system, an insulated fenestration system, and a method for insulating a fenestration system are disclosed. The simulated steel fenestration system can comprise a frame, a pane assembly assembled with the frame, and a muntin bar, wherein at least one of the frame and the muntin bar comprise a non-steel material configured to resemble steel.

A façade system includes a mullion having exterior and interior portions and defining a glazing pocket between the exterior and interior portions, a thermal break arranged within the glazing pocket and extending between the exterior and interior portions, the thermal break dividing the glazing pocket into a shallow pocket and a deep pocket larger than the shallow pocket, and a collapsible element arranged within the deep pocket and extending between the thermal break and a lateral side of a panel introduced into the deep pocket. The collapsible element is movable between a collapsed state and an expanded state. The collapsible element divides the deep pocket into two or more thermal chambers when in the expanded state to reduce heat transfer by convection through the glazing pocket.

A structure for blocking heat transfer through a thermal bridge of a building, includes an inner visual glass curtain wall, an outer visual glass curtain wall, an indoor metal frame, an outdoor metal frame, an outer decorative metal cover, a first thermal break strip, a second thermal break strip, a first nylon thermal break block and a second nylon thermal break block. The first thermal break strip, which is located in contact with the outdoor metal frame, the indoor metal frame, the first nylon thermal break block and the second nylon thermal break block, is an aerogel thermal insulation blanket. The second thermal break strip, which is located in contact with the indoor metal frame, the second nylon thermal break block, the outer decorative metal cover and the inner visual glass curtain wall, is another aerogel thermal insulation blanket.

A fenestration formed of flattened steel with special thermal break structures therein.

The clamping assembly for a glass door includes an outer clamping body, an inner clamping body, an automatic homing mechanism and a positioning unit. An upper jaw for clamping the glass door is provided on the top of the outer clamping body, and a first side wall and a second side wall are recessedly formed at the bottom of the outer clamping body. A first lower jaw is formed between the first side wall and the second side wall. The inner clamping body is disposed in the first lower jaw. A second lower jaw is formed at the bottom of the inner clamping body. The automatic homing mechanism is disposed in the second lower jaw. The positioning unit penetrates the first side wall to abut against the first recess on the inner clamping body.

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.

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 faade system includes a mullion having exterior and interior portions and defining a glazing pocket between the exterior and interior portions, a thermal break arranged within the glazing pocket and extending between the exterior and interior portions, the thermal break dividing the glazing pocket into a shallow pocket and a deep pocket larger than the shallow pocket, and a collapsible element arranged within the deep pocket and extending between the thermal break and a lateral side of a panel introduced into the deep pocket. The collapsible element is movable between a collapsed state and an expanded state. The collapsible element divides the deep pocket into two or more thermal chambers when in the expanded state to reduce heat transfer by convection through the glazing pocket.
