This application claims the benefit of U.S. provisional app. 63/635,209 filed Apr. 17, 2024, which is incorporated by reference.

This disclosure relates generally to a wall bracket and, in particular, to a façade cladding system that includes a bracket having an isolator pad for fastening a sub-frame assembly to a load-bearing wall.

Façade systems may be used to provide exterior surfacing for buildings or structures. The façade system may not only provide aesthetic style or character to a building or structure, but the façade system may also impact the durability and energy efficiency of the building or structure, as well as weather protection for the building or structure and UV protection for people inside the building or structure. Façade systems may include brackets for fastening a number of different elements, such as facades panels or sheets, including rainscreen panels, as the exterior surface of a building or structure.

This disclosure relates generally to a wall bracket and, in particular, to a façade cladding system that includes a bracket having an isolator pad for fastening a sub-frame assembly to a load-bearing wall. The bracket and sub-frame assembly are designed to simplify the process of building façade walls, and, in particular, rainscreen walls of all types including CI sub-framing and panel sub-framing. In some embodiments, the bracket is designed to provide low thermal conductivity across the bracket, e.g., low thermal bridging effects, then assemblies that include high thermal conductivity brackets, e.g., aluminum brackets. In some embodiments, the low thermal conductivity may be provided using an isolator pad that may be a hard plastic or a soft plastic that provides material separation, e.g., bracket from the wall, and a thermal break, e.g., by being made of an enhanced thermal resistant material. As such, the isolator pad may reduce heat loss and significantly decrease thermal bridging effects, e.g., between the bracket and the wall. That is, while current bracket designs may have thermal inefficiencies, and fundamental installation efficiencies, the brackets including the isolator pads, as described herein, are configured to be more thermally efficient, and easier to install than current bracket designs. In some embodiment, the bracket that includes the isolator pad may meet the American Society of heating, Refrigerating and Air-Conditioning (ASHRAE) Standard 90.1-2019, e.g., 0.90 and/or a minimum value of 0.75.

In an embodiment, an isolator pad for a bracket for fastening a sub-frame assembly is provided. The isolator pad includes a planar portion corresponding to a planar base portion of the bracket; a plurality of fastening tabs provided on a periphery of the planar portion configured to attach to the planar base portion of the bracket; and a plurality of fixing holes provided on the planar portion that correspond to a plurality of fixing holes provided on the planar base portion of the bracket.

In another embodiment, a bracket for fastening a sub-frame assembly that includes an isolator pad is provided. The bracket includes a planar base portion; a planar flanged portion that is fixable or slidable connected to the planar base portion at a connection joint; a plurality of fixing holes provided on the planar base portion and the planar flanged portion that is fixable or slidable; and at least one strengthening rib provided on the planar base portion, the connection joint, and the planar flanged portion that is fixable or slidable. The planar flanged portion that is fixable or slidable includes a thumb hold portion configured to engage the sub-frame assembly, and the planar base portion is configured to be connected to a load-bearing wall. The bracket further includes an isolator pad connected to the planar base portion of the bracket, the isolator pad including a planar portion corresponding to the planar base portion of the bracket; a plurality of fastening tabs provided on a periphery of the planar portion that attach the planar portion to the planar base portion of the bracket; and a plurality of fixing holes provided on the planar portion that correspond to the plurality of fixing holes provided on the planar base portion of the bracket.

This disclosure relates generally to a wall bracket and, in particular, to a façade cladding system that includes a bracket having an isolator pad for fastening a sub-frame assembly to a load-bearing wall. The bracket and sub-frame assembly are designed to simplify the process of building façade walls, and, in particular, rainscreen walls of all types including CI sub-framing and panel sub-framing. In some embodiments, the bracket is designed to provide low thermal conductivity across the bracket, e.g., low thermal bridging effects, then assemblies that include high thermal conductivity brackets, e.g., aluminum brackets. In some embodiments, the low thermal conductivity may be provided using an isolator pad that may be a hard plastic or a soft plastic that provides material separation, e.g., bracket from the wall, and a thermal break, e.g., by being made of an enhanced thermal resistant material. As such, the isolator pad may reduce heat loss and significantly decrease thermal bridging effects, e.g., between the bracket and the wall. That is, while current bracket designs may have thermal inefficiencies, and fundamental installation efficiencies, the brackets including the isolator pads, as described herein, are configured to be more thermally efficient, and easier to install than current bracket designs. In some embodiment, the bracket that includes the isolator pad may meet the American Society of heating, Refrigerating and Air-Conditioning (ASHRAE) Standard 90.1-2019, e.g., 0.90 and/or a minimum value of 0.75.

In an embodiment, the façade cladding system may be a rainscreen cladding system that is configured to thermally insulate the building or structure and prevent moisture or water from entering the building or structure. The rainscreen cladding system may be a building façade that is designed to restrict water, e.g., rain and moisture, from entering the insulation and building and has an air cavity to allow for constant air circulation, e.g., ventilation, of the cavity between the rainscreen panels and the load-bearing wall. That is, the rainscreen cladding system may be a two-stage construction that includes an inner insulated wall that is protected by an outer skin or shell formed of panels. The rainscreen cladding system may include a plurality of brackets, a plurality of horizontal sub-frame assemblies for accommodating insulation, a plurality of secondary portions, rainscreen panels, and insulation. As such, the rainscreen cladding system may be configured to provide thermal insulation, prevent excessive air leakage, and carry the wind loading and dead loading to prevent bending or failure of the rainscreen cladding system.

In an embodiment, the bracket(s) may be used to immovably fix or secure the sub-frame assemblies to a load-bearing wall. The load-bearing wall may be formed from concrete or masonry and/or include metal studs for attachment and securement of the sub-frame assemblies. In an embodiment, the bracket(s) may be positioned horizontally such that the fixed point connection holes of the bracket provided along the centerline of the planar base portion may receive fasteners for immovably fixing or securing the bracket(s) to the metal studs of the load-bearing wall. In an embodiment, a continuous insulation sheet may be provided between the bracket(s) and the load-bearing wall, which may reduce air and water leakage into the building and/or reduce thermal bridging or driving affects from the environment and/or bracket(s) into the building.

After the bracket(s) are fixed or secured to the load-bearing wall, the sub-frame assemblies which may include the insulation may be temporarily positioned by the bracket(s) via the thumb hold portions of the bracket(s). Fasteners are then used to temporarily fix or hold the sub-frame assemblies via the oblong holes, such that the thumb hold portion and the oblong holes may be used to accommodate plumb conditions of the sub-frame assemblies. After the sub-frame assemblies have been plumbed, fasteners may be used to immovably fix or secure the sub-frame assemblies to the bracket(s) via the fixed connection holes on the planar flanged portion that is fixable or slidable of the bracket. The insulation may be a material that is installed in the walls of a building to reduce heat transfer and energy loss, such as, fiberglass, cellulose, polyurethane, or other insulative material.
