COMPOSITE THERMAL ISOLATING MASONRY TIE FASTENER
Cavity walls include fasteners that provide a thermal break. A cavity wall assembly includes a support structure, insulation, and an outer wythe. The insulation is mounted on the support structure. The outer wythe is spaced apart from the insulation, such that a cavity is formed between the insulation and the outer wythe. A tie is attached to the outer wythe. A fastener extends through a portion of the tie, through the insulation, and into the support structure to attach the tie to the support structure. The fastener provides a thermal break between the support structure and the tie. At least a portion of the thermal break is disposed within a width of the insulation.
This application claims priority to U.S. Provisional Application Ser. No. 61/900,449, filed Nov. 6, 2013, titled COMPOSITE THERMAL ISOLATING MASONRY TIE FASTENER”, the entire disclosure of which is incorporated by reference in its entirety.
FIELD OF THE INVENTIONThe present inventions relate to thermally isolated anchoring systems for insulated walls. In particular, the present invention relates to anchoring systems that minimize heat transfer through a fastener that extends through an insulation material.
BACKGROUND OF THE INVENTIONPublished US Patent Application Pub. No. 2011/0047919 provides a background of anchoring systems. Portions of US Patent Application Pub. No. 2011/0047919 are incorporated below. US Patent Application No. 2011/0047919 is incorporated herein by reference in its entirety.
In the past, anchoring systems have taken a variety of configurations. The construction of a steel frame of a commercial or residential building, to which masonry veneer is attached, uses steel studs with insulation installed outboard of the steel stud framing. Steel anchors and ties attach the outer masonry wythe to the inner steel stud framing by screwing or bolting an anchor to a steel stud. Steel is an extremely good conductor of heat. The use of steel anchors attached to steel framing draws heat from the inside of a building through the exterior sheathing and insulation, towards the exterior of the masonry wall. US Patent Application No. 2011/0047919 recognizes that in order to maintain high insulation values, a thermal break or barrier is needed between the steel framing and the outer wythe.
SUMMARYThe present application discloses fasteners that provide a thermal break in cavity walls. In one exemplary embodiment, a cavity wall assembly includes a support structure, insulation, and an outer wythe. The insulation is mounted on the support structure. The outer wythe is spaced apart from the insulation, such that a cavity is formed between the insulation and the outer wythe. A tie is attached to the outer wythe. A fastener extends through a portion of the tie, through the insulation, and into the support structure to attach the tie to the support structure. The fastener provides a thermal break between the support structure and the tie. For example, in one exemplary embodiment, at least a portion of the thermal break is disposed within a width of the insulation.
In the accompanying drawings which are incorporated in and constitute a part of the specification, embodiments of the invention are illustrated, which, together with a general description of the invention given above, and the detailed description given below, serve to provide examples of the principles of this invention.
As described herein, when one or more components are described as being connected, joined, affixed, coupled, attached, or otherwise interconnected, such interconnection may be direct as between the components or may be indirect such as through the use of one or more intermediary components. Also as described herein, reference to a “member,” “component,” or “portion” shall not be limited to a single structural member, component, or element but can include an assembly of components, members or elements.
In the embodiments described herein, the inner wythe is provided with insulation. In exemplary embodiments disclosed herein, the insulation is applied to the outer surface thereof of sheathing and/or drywall. Anchoring systems for cavity wall assemblies are used to secure veneer facings to a building and overcome seismic and other forces, i.e. wind shear, etc.
