Description:
CROSS-REFERENCE TO RELATED APPLICATIONS 
     This application claims priority to U.S. Provisional Application No. 62/093,032, filed Dec. 17, 2014, the content of which is incorporated herein by reference. 
    
    
     FIELD OF THE INVENTION 
     The present invention generally relates to an anchor and to an assembly for a structure, more specifically to an anchor and to an assembly comprising interior and exterior building components, with the anchor disposed between the building components and having a thermal break for reducing thermal bridging between the building components while the building components are subject to a temperature difference between the building components. 
     DESCRIPTION OF THE RELATED ART 
     In many commercial or industrial buildings, L- or Z-brackets are used to mechanically attach external building components (e.g. cladding) to internal building components (e.g. structural walls or sub-frames). A continuous span of insulation is often in contact with at least the internal building component. The brackets pass through seams in the insulation so that the external component can be attached to the brackets, which were previously attached to the interior building component. The brackets transfer climactic loads (e.g. wind loads) of the environment from the external building component to the internal building component. The brackets must be strong enough to support climactic loads and also weight of the external building component(s). Therefore, the brackets are often formed from metal (e.g. steel or aluminum). Unfortunately, since the aforementioned brackets are formed from metal, they act as direct thermal shorts between the exterior and interior building components. Various systems have been proposed in an effort to reduce heat transfer (i.e., heat loss or gain) between building components. 
     One system utilizes a ThermaStop™ thermal isolation system, which is commercially available from Knight Wall Systems of Deer Park, Wash. The ThermaStop™ system utilizes 55 AL-ZN-coated steel brackets with plastic bases and integral ⅛-inch plastic washers. While the ThermaStop™ system has a relatively narrow cross-section, the cross-section is formed from steel which passes through insulation and acts as a direct thermal short. 
     Another system utilizes a CASCADIA CLIP®, which is commercially available from Cascadia Windows Ltd. of Langley, BC, Canada. The CASCADIA CLIP® is a fiberglass girt spacer, and is illustrated in U.S. Design Pat. No. D666,894 S to Bombino et al. and U.S. Patent Application Publication No. US2013/0174506 A1 to Bombino et al. While formed from fiberglass, the CASCADIA CLIP® relies on conventional metal fasteners (e.g. lag screws) that act as direct thermal shorts. In addition, the CASCADIA CLIP® can be difficult and time consuming to install. 
     Another system utilizes a thermal insulation material (TIM), which is commercially available from FABREEKA® of Boston, Mass. The TIM is manufactured from a fiberglass-reinforced laminate composite. While formed from fiberglass, the TIM is a merely a pad used between flanged steel connections. The steel connections must be connected via conventional metal fasteners (e.g. bolts) that act as direct thermal shorts. In addition, the TIM can be difficult and time consuming to install. 
     Yet another system utilizes a POS-I-TIE® ThermalClip®, which is commercially available from Heckmann Building Products, Inc. of Melrose Park, Ill. The ThermalClip® is formed from polyphenylsulfone (PPSU), has a snap on design, and is described in U.S. Patent Application Publication No. US2013/0232909 A1 to Curtis et al. The ThermalClip® is used in masonry construction. While formed from PPSU, the ThermalClip® relies on conventional metal wire ties that can act as direct thermal shorts. In addition, the ThermalClip® can be difficult and time consuming to install. 
     In view of the foregoing, there remains an opportunity to provide systems that reduce or negate heat transfer. There also remains an opportunity to provide systems that are easier and less time consuming to install. 
     SUMMARY OF THE INVENTION 
     An anchor is disclosed. The anchor is useful for securing an exterior building component to an interior building component. The anchor comprises a first end having an outer side for engaging the interior building component. The anchor also comprises an inner side opposite the outer side of the first end. The anchor further comprises a second end having an outer side for engaging the exterior building component. The anchor yet further comprises an inner side opposite the outer side of the second end. The inner sides of the ends face each other. A space is defined between the inner sides of the ends. A thermal break is disposed in the space. The thermal break has a first coupling surface bonded to the inner side of the first end. The thermal break also has a second coupling surface opposite the first coupling surface and bonded to the inner side of the second end. Thermal conductivity of the thermal break is lower than thermal conductivity of at least one of the ends. The thermal break generally reduces thermal bridging between the building components while the building components are subject to a temperature difference between the building components. 
     An assembly is also disclosed. The assembly comprises the interior and exterior building components, which are spaced from each other to define the space. The anchor is disposed between the building components. The anchor secures the exterior building component to the interior building component, and generally reduces thermal bridging therebetween. The assembly is useful for a structure, such as for a building. 
     A method is also disclosed. The method entails securing the exterior building component to the interior building component. The method comprises the steps of providing the anchor and attaching the anchor to one of the building components to form a sub-assembly. The method further comprises the step of connecting the sub-assembly and the remaining building component to secure the building components.

     DETAILED DESCRIPTION OF THE INVENTION 
     Referring to the Figures, wherein like numerals indicate like parts throughout the several views, an anchor is shown generally at  20 . The anchor  20  is useful for securing an exterior building component  46  to an interior building component  48 . The building components  46 ,  48  are described further below and illustrated in  FIGS. 3-6 . 
     The anchor  20  comprises a first end  22  having an outer side  24 . The outer side  24  is useful for engaging the interior building component  46 . The anchor  20  further comprises an inner side  26  opposite the outer side  24  of the first end  22 . The first end  22  can be of various sizes, dimensions, and shapes. Referring to  FIG. 1 , the first end  22  is generally configured as a T-bracket. As shown in  FIG. 2 , the first end  22  is generally configured as a flat-bracket. While the T- and flat-bracket configurations (or designs) are shown, the first end  22  can be of various configurations and is not limited to a particular one. 
     The anchor  20  further comprises a second end  28  having an outer side  30 . The outer side  30  is useful for engaging the exterior building component. The anchor  20  yet further comprises an inner side  32  opposite the outer side  30  of the second end  28 . The second end  28  can be of various sizes, dimensions, and shapes. As shown in  FIGS. 1 and 2 , the second end  28  is generally configured as a T-bracket. While the T-bracket configuration is shown, the second end  28  can be of various configurations and is not limited to a particular one. The second end  28  can be the same as or different from the first end  22 . For example, the ends  22 , 28  may be mirror images of each other as best shown in  FIG. 1B , or different from each other as shown in  FIG. 2 . 
     The inner sides  26 ,  32  of the ends  22 ,  28  generally face each other. Typically, the inner sides  26 ,  32  are substantially parallel each other; however, this is not required. A space  34  is generally defined between the inner sides  26 ,  32  of the ends  22 ,  28 . The space  34  can be of various dimensions. 
     Other configurations, designs, or profiles that may be utilized for at least one of the ends  22 , 28 , and/or for the anchor itself  20 , include those that mimic conventional L-brackets, Z-brackets, U-brackets, C-brackets, I-brackets, H-brackets, hanging-brackets, hat-brackets, stirrup-brackets, flat-brackets, split-bend-anchors, etc. The anchor  20  can be configured to mimic various types of conventional anchors utilized in construction for securing building components together. The anchor  20  may also be referred to as a tie, clip, or bracket. A person of ordinary skill in the art can select an appropriate configuration of the ends  22 ,  28 , and/or the anchor  20  based on use, location, load, etc., of the anchor  20 . 
     Optionally, the ends  22 ,  28  can individually define at least one hole  36 . The hole  36  can be of various sizes, dimensions, and shapes. The hole  36  can be used for attaching the first end  22  to the interior building component and/or for attaching the second end  28  to the exterior building component. The hole  36  can be used in combination with a fastener. Examples of suitable fasteners include, but are not limited to, bolts, screws, pins, ties, nails, rivets, adhesives, etc. The disclosure is not limited to a particular type of fastener. The hole(s)  36  can be pre- or post-formed in the end(s)  22 ,  28 , e.g. by casting, machining, stamping, drilling, etc. 
     Typically, each of the ends  22 ,  28  individually comprise a rigid material. Examples of suitable rigid materials include, but are not limited to, metallic materials, polymeric materials, composite materials, and combinations thereof. In various embodiments, each of the ends  22 ,  28  comprise a metallic material. In these embodiments, each of the ends  22 ,  28  can individually comprise an elemental metal or an alloy thereof. Examples of suitable metals include, but are not limited to, transition and post-transition metals, such as iron, copper, aluminum, zinc, etc. In certain embodiments, each of the ends  22 ,  28  comprise iron. In specific embodiments, each of the ends  22 ,  28  comprise steel. Various grades of steel (SAE Steel Grades) can be used to form the ends  22 ,  28 , such as 200 or 300 series stainless steel. In a specific embodiment, SAE Steel Grade 304 stainless steel is used to form each of the ends  22 ,  28 . A person of ordinary skill in the art can select an appropriate material for each of the ends  22 ,  28  based on use, location, load, etc., of the anchor  20 . 
     A thermal break  38  is disposed in the space  34 . The thermal break  38  has a first coupling surface  40  bonded to the inner side  26  of the first end  22 . The thermal break  38  also has a second coupling surface  42  opposite the first coupling surface  40 . The second coupling surface  42  is bonded to the inner side  32  of the second end  28 . 
     Typically, the thermal break  38  adhesively bonds the ends  22 ,  28  together. Said another way, the first coupling surface  40  is generally adhered to the inner side  26  of the first end  22 , and the second coupling surface  42  is generally adhered to the inner side  32  of the second end  28  during normal usage. Adhesion is generally the tendency of dissimilar surfaces to cling to one another. In further embodiments, the thermal break  38  exclusively bonds the ends  22 ,  28  together. In these embodiments, the anchor  20  is free of supplemental means for connecting the ends  22 ,  28  together. In other words, the ends  22 ,  28  are attached together exclusively by the thermal break  38  and nothing more. Examples of such supplemental means include, but are not limited to, fasteners such as bolts, pins, screws, etc. 
     The thermal break  38  can be of various dimensions. As best shown in  FIG. 1B , the thermal break  38  generally has a height (H), width (W), and thickness (T). Each of the height (H), width (W), and thickness (T) of the thermal break  38  can be uniform or can vary. A person of ordinary skill in the art can select an appropriate height (H), width (W), and thickness (T) of the thermal break  38  based on use, location, load, etc., of the anchor  20 . 
     The thermal break  38  can have various cross-sectional areas, as generally defined by its height (H) and width (W). In various embodiments, the thermal break  38  has a cross-sectional area (H*W) of from about 1 to about 800, about 1 to about 300, about 1 to about 200, about 5 to about 100, about 5 to about 50, about 10 to about 40, about 20 to about 40, or about 30 square centimeters (cm 2 ), or any subrange between about 1 and about 800 cm 2 . Alternatively, the thermal break  38  can have a cross-sectional area (H*W) of from about 0.5 to about 120 square inches (in 2 ) (3.23-774 cm 2 ), about 0.5 to about 80 in 2  (3.23-516 cm 2 ), about 2 to about 40 in 2  (12.9-258 cm 2 ), about 2 to about 20 in 2  (12.9-129 cm 2 ), about 4 to about 16 in 2  (25.8-103.2 cm 2 ), about 8 to about 16 in 2  (50.6-103.2 cm 2 ), or about 12 in 2  (77 cm 2 ), or any subrange between about 0.5 and about 120 in 2 , (3.23-774 cm 2 ). A person of ordinary skill in the art can select an appropriate cross-sectional area (H*W) of the thermal break  38  based on use, location, load, etc., of the anchor  20 . 
     The thermal break  38  can have various average thicknesses, as generally defined by its thickness (T). In various embodiments, the thermal break  38  has an average thickness (T) of from about 1 to about 50, about 1 to about 40, about 1 to about 30, about 1 to about 20, about 2 to about 10, about 4 to about 8, or about 6, millimeters (mm), or any subrange from about 1 to about 40 mm. Alternatively, the thermal break  38  has an average thickness (T) of from about 0.05 to about 2 inches (in) (1.27-50.8 mm), about 0.05 to about 1.5 in (1.27-38.1 mm), about 0.05 to about 1.25 in (1.27-31.75 mm), about 0.05 to about 1 in (1.27-25.4 mm), about 0.1 to about 0.75 in (2.54-19.05 mm), about 0.25 to about 0.5 in (6.35-12.7 mm), or about 0.25 in (6.35 mm), or any subrange from about 0.05 to about 2 in (1.27-50.8 mm). A person of ordinary skill in the art can select an appropriate average thickness (T) of the thermal break  38  based on use, location, load, thermal performance requirements, etc., of the anchor  20 . 
     Optionally, at least a portion of the thermal break  38  can be molded over at least a portion of at least one of the ends  22 ,  28 . While not required, it is thought that overmolding may be useful to increase strength (e.g. sheer strength) of the anchor  20 . Optionally, at least one of the inner sides  26 ,  32  of the ends  22 ,  28  can include one or more surface protrusions. While not required, it is thought that surface protrusions may be useful to increase strength (e.g. sheer strength) of the anchor  20 . Surprisingly, it has been found that strength of the anchor  20  is still adequate even when the inner sides  26 ,  32  of the ends  22 ,  28  are substantially smooth (e.g. prior to disposing or forming the thermal break  38 ). A person of ordinary skill in the art can select an appropriate option (e.g. overmolding and/or protrusions) based on use, location, load, etc., of the anchor  20 . 
     The thermal break  38  typically comprises a rigid, semi-rigid, semi-flexible, or flexible material. It is thought that such a material can allow for varying degrees of movement between the ends  22 ,  28  of the anchor  20 . For example, some amount of settling, flexing, expansion, and/or contraction can occur with certain building components. Exterior building components are especially prone to movement when subject to climatic loads (e.g. wind load) and/or variations in temperature (e.g. when exposed to sunlight on a cool/cold day). Other types (or forms) of load include dead, live, building, environmental, and gravity loads, and the disclosure is not limited to a particular one. 
     Typically, the thermal break  38  is formed from a material different from at least one of the ends  22 ,  28  more typically different from both of the ends  22 ,  28 . In various embodiments, the thermal break  38  comprises a polymeric material. Various types of polymer chemistries can be utilized to form the thermal break  38 , including, but not limited to, elastomers (or rubber), silicone or silicone rubber, or rigid materials such as epoxies or epoxy adhesives. 
     In various embodiments, the thermal break  38  comprises an elastomer (or rubber). Examples of suitable elastomers include, but are not limited to, thermoplastic elastomers (TPEs), unsaturated rubbers, saturated rubbers, and mixtures thereof. 
     Specific examples of suitable TPEs include, but are not limited to, styrenic block copolymers, polyolefins, elastomeric alloys, polyurethanes, copolyesters, and polyamides. Mixtures of TPEs may also be used. In certain embodiments, the thermal break  38  is formed from a polyurethane (e.g. a thermoplastic polyurethane, or TPU). 
     Specific examples of suitable unsaturated rubbers include, but are not limited to, those that can be cured by sulfur vulcanization such as polyisoprenes, polybutadienes, chloroprenes, butyl rubbers, styrene-butadienes, and nitrile rubbers. Certain unsaturated rubbers can also be cured by means other than by sulfur vulcanization. Mixtures of unsaturated rubbers may also be used. 
     Specific examples of suitable saturated rubbers include, but are not limited to, ethylene propylene rubber (EPM), ethylene propylene diene rubber (EPDM), epichlorohydrin rubber, polyacrylic rubber, silicone rubber, fluorosilicone rubber, fluoroelastomers, perfluoroelastomers, polyether block amides, chlorosulfonated polyethylene, and ethylene-vinyl acetate. Mixtures of saturated rubbers may also be used. In certain embodiments, the thermal break  38  is formed from EPDM. 
     In various embodiments, the thermal break  38  comprises silicone. In further embodiments, the thermal break  38  comprises silicone rubber. The silicone rubber may also be referred to as a silicone elastomer. Various types of silicone rubbers can be used to form the thermal break  38 . The silicone rubber may be cured, for example, by an addition cure system, a condensation cure system, or a peroxide cure system. 
     In various embodiments, the silicone rubber is cured by a heat cure system. Heat cure systems typically rely on addition cure mechanisms using platinum-based catalysts or peroxide cure mechanisms to facilitate cure. The curing process can be accelerated by adding heat and/or pressure. Examples of suitable silicone rubbers include those commercially available from Dow Corning Corporation of Midland, Mich., such as SILASTIC® Silicone Rubbers (e.g. SILASTIC® TR-70 Silicone Rubber). 
     Alternatively, the thermal break  38  is formed from a condensation cured silicone structural adhesive or condensation cured silicone structural sealant which forms a suitable elastomeric material upon curing. Examples of suitable silicone structural adhesive or condensation cured silicone structural sealant include those commercially available from Dow Corning Corporation of Midland, Mich., for example DOW CORNING® Silicone Structural Sealants (e.g. DOW CORNING® 995 Silicone Structural Sealant). 
     In various embodiments, the thermal break  38  comprises an epoxy or an epoxy adhesive. In certain of these embodiments, the epoxy or epoxy adhesive cures to form a rigid material that provides and maintains sufficient adherence and desired adhesive strength to the respective inner sides  26 ,  32  of the first and second end  22 ,  28  during usage. 
     In embodiments where the thermal break  38  comprises a polymeric material, e.g. elastomers, silicone or epoxy, the thermal break  38  generally has a very low thermal conductivity. For example, the thermal break  38  can have a thermal conductivity that is over 2, 5, 10, 25, 50, or 100 times less than that of metallic materials such as steel. The thermal break  38 , and therefore the anchor  20 , can be configured to have a fail safe flame resistance. For example, the anchor  20  can be configured to have a mechanical catch that will allow the ends  22 ,  28  to maintain structural engagement in the event a fire burns away the polymeric thermal break  38 . This is evaluated by testing to NFPA 285 (National Fire Protection Association Test 285—Standard First Test Method for Evaluation of Fire Propagation Characteristics of Exterior Non-Load-Bearing Wall Assemblies Containing Combustible Components (copies of test available from NFPA of Quincy, Mass.)). The anchor  20  can also be configured to be tolerant in “freeze-thaw” conditions, and/or be configured to be tolerant of alkalines in mortar. 
     The anchor  20  can be made by various manufacturing methods, and the disclosure is not limited to a particular one. In certain embodiments, the anchor  20  is made by injection molding. In these embodiments, the material utilized to form the thermal break  38  (e.g. a silicone composition) is injected between the ends  22 ,  28  while in a mold. Heat and/or pressure can be utilized to accelerate cure of certain materials, e.g. silicone rubber. Other molding methods can also be used, such as compression molding. A person of ordinary skill in the art can select an appropriate method of manufacture based on the materials used to form the anchor  20 . 
     An assembly (shown as  50  in the alternative embodiments of  FIGS. 3-6 , respectively). The assembly  50  is useful for a structure, and can be used in the construction industry. The structure is typically a building, and the disclosure is not limited to a particular one. Examples of buildings include, but are not limited to, residential, commercial, and industrial buildings, such as single story, mid-rise, and high-rise buildings. 
     The assembly  50  includes an interior building component (shown as  48  in  FIGS. 3-6 , respectively). The interior building component  48  can be any type of conventional interior building component, and the disclosure is not limited to a particular one. Examples of suitable interior building components include, but are not limited to, studs, beams, rails, joists, ties, trusses, mounts, braces, frames, walls, and supports. The interior building component can include one or more of the prior examples. 
     The assembly  50  further includes an exterior building component (shown as  46  in  FIGS. 3-6 , respectively) spaced from the interior building component  48 . The exterior building component  46  can be any type of conventional exterior building component, and the disclosure is not limited to a particular one. Examples of suitable exterior building components include, but are not limited to, rain screens, curtain walls, bricks, masonry, stones, timbers, panels, siding, facades, cladding, girts, rails, walls, sills, lintels, headers, and mullions. The exterior building component can include one or more of the prior examples. The examples listed above for the interior and exterior building components is not an all inclusive list. Further, that which is described as an interior building component may also be used as an exterior building component and vice versa. The disclosure is not limited to a particular designation of the building components. 
     The assembly  50  further includes the anchor  20  as described in  FIGS. 1-2  above. The anchor  20  is disposed between the interior  48  and exterior building components. The anchor  20  generally secures the exterior building component  46  to the interior building component  48  (or vice versa). 
     Optionally, the assembly  50  can further include one or more conventional building components. The disclosure is not limited to a particular type or number of conventional building components. In various embodiments, the assembly further comprises at least one fastener. Examples of suitable fasteners include, but are not limited to, bolts, screws, pins, nails, rivets, adhesives, etc. The disclosure is not limited to a particular type of fastener. If used, the fastener is generally used in connection with the hole  36 . Further, if used, the fastener  36  generally does not operatively connect the ends  22 ,  28  together, e.g. by spanning between the ends  22 ,  28 . 
     In various embodiments, the assembly  50  further includes insulation. The insulation can be disposed around the anchor  20 , between the anchor  20  and at least one of the building components, and/or between the building components. Examples of suitable types of insulation include, but are not limited to, batts and blankets, loose-fill Insulation, structural insulated panels (SIPs), spray foam, vacuum insulated panels (VIPs), etc. Further examples of suitable types of insulation include, but are not limited to, fiberglass, mineral wool, glass wool, rock wool, cotton, expanded polystyrene (EPS), extruded polystyrene (XPS), polyisocyanurate (“polyiso”), open- or closed-cell polyurethane foam, cellulose, aerogel, etc. Optionally, one or more fasteners may be used to hold the insulation in place, such as stick pins, clips, etc. The disclosure is not limited to a particular type of insulation or fastener thereof. 
     Thermal conductivity of the thermal break  38  is lower than thermal conductivity of at least one of the ends  22 ,  28 . In certain embodiments, thermal conductivity of the thermal break  38  is lower than the thermal conductivity of each (or both) of the ends  22 ,  28 . The thermal break  38  may also be referred to as a thermal barrier. The lower thermal conductivity of the thermal break  38  generally reduces thermal bridging between the building components while the interior and exterior building components are subject to a temperature difference between the building components. In general, the thermal break  38  reduces or prevents the flow of thermal energy between the ends  22 ,  28 , and therefore, reduces or prevents the flow of thermal energy (or heat transfer) between the interior and exterior building component. The disclosure is not limited to a particular direction of thermal energy flow (i.e., inward, outward, or neutral). 
     A thermal bridge (also referred to as a cold bridge or thermal short), is a fundamental of heat transfer where a penetration of an insulation layer by a highly conductive or non-insulating material takes place in the separation between the interior (or conditioned space) and exterior environments of a building assembly (also referred to as the building enclosure, building envelope, or thermal envelope). Thermal bridging is created when materials that are poor thermal insulators come into contact, allowing heat to flow through the path of least thermal resistance created, although nearby layers of material separated by insulation and or by airspace allow little heat transfer. For example, sun shades anchored to the side of a building typically go through the insulation and their anchorage creates a thermal bridge to the building&#39;s interior. 
     In general, insulation around a thermal bridge is of little help in preventing heat loss or gain due to thermal bridging. As an example, if thermal bridges at balconies of a building are not taken care of, the balconies can act as “cooling fins”. Such cooling fins conduct heat off the building and cool rooms adjacent to the balconies. A wall with a thermal bridge may be analogized to a bucket with a hole in it. Adding insulation without breaking thermal bridges is like increasing the thickness of the walls of the bucket but not plugging the hole. In various embodiments utilizing insulation, the only part that breaks the insulation layer is the thermal break  38 . In this way, foam wall boards for example, can be used in a way that provides truly continuous insulation. 
     A method is also disclosed. The method is useful for securing the exterior building component  46  to the interior building component  48 . The method includes the step of providing the anchor  20 . The method further includes the step of attaching the anchor  20  to one of the building components to form a sub-assembly. For example, the anchor  20  can be attached to the interior building component  48  or to the exterior building component  46  to form the sub-assembly. 
     The method yet further comprises the step of connecting the sub-assembly and the remaining building component to secure the exterior building component  46  to the interior building component  48 . For example, the exterior building component  46  can be attached to a sub-assembly including the anchor  20  and the interior building component  48 . Conversely, the interior building component  48  can be attached to a sub-assembly including the anchor  20  and the exterior building component  46 . One or more fasteners may be utilized for such attachment. 
     One or more anchors  20  can be utilized to attach the building components  46 ,  48  of a structure. A person of ordinary skill in the art can select an appropriate number of anchors  20  based on the use, location, load, etc., of the anchors  20 . The same can be said for determining the size, configuration, and location of the anchors  20 . The anchor  20  should be of a sufficient size to support the exterior building component  46  from both climactic and gravity loads. The anchor  20  can be designed based on end application. In certain embodiments, the anchor  20  and/or the assembly  50  can be designed to be fire safe by including additional mechanical clips that engage when and if the polymeric thermal break material  38  is burned away in a fire, wherein this system can be verified with testing to NFPA 285. 
     Referring to  FIG. 3 , a photograph of a portion of an assembly  50  is illustrated as having exterior building components  46 , interior building components  48 , clips  56 , and rigid foam insulation  60  is shown. The assembly  50  is just one example of a possible configuration of an assembly in which the anchor  20  of the disclosure can be utilized, e.g. in place of, or in addition to, the clips  56 . 
       FIG. 4  illustrate an exploded view of another embodiment of an assembly  50  that includes the anchor  20  according to  FIG. 2  disposed between an exterior building component  46  and an interior building component  48  for securing the exterior building component  46  to the interior building component  48 . 
     In  FIG. 4 , the outer side  24  of a first end  22  of the anchor  20  is positioned against an outer surface  156  of the exterior building component  46 . A fastener  165 , shown herein as a screw  165 , is inserted through a respective hole  36  and secures the second end  28  to the exterior building component  46 . Additional fasteners  165  are also inserted through the holes  36  in the second end  28  to secure the interior building component  48  to the second end  28 . 
     As also illustrated in  FIG. 4 , a thermal break  38  is disposed in the space  34  between the first end  22  and the second end  28 . The thermal break  38  has a first coupling surface  40  bonded to the inner side  26  of the first end  22 . The thermal break  38  also has a second coupling surface  42  opposite the first coupling surface  40 . The second coupling surface  42  is bonded to the inner side  32  of the second end  28 . In this embodiment, as described above, the thermal conductivity of the thermal break  38  is lower than the thermal conductivity of at least one of the ends  22 , 28  to reduce thermal bridging between the exterior building component  46  and the interior building component  48  while such building components  46 , 48  are subject to temperature differences. Rigid foam insulation (not shown) may also be positioned between the exterior building component  46  and the interior building component  48  in a space between the interior building component  46  and the exterior building component  48  and adjacent to the space  34  not defined by the anchor  20 . 
     In another embodiment of the present invention, as illustrated in  FIGS. 5 and 6 , the assembly  50  includes wherein the inner side  26 ,  32  of each of the first and second ends  22 ,  28  of an anchor  20  in accordance with another embodiment of the invention are configured to include a catch structure  72 ,  74  that are complementary with each other. The catch structures  72 ,  74  are designed to mechanically interlock, or engage one another, in the event of a fire burning away the thermal break  38  or other situations in which the thermal break  38  is removed. As such, in  FIG. 5 , wherein the thermal break  38  is present, the catch structures  72 ,  74  are positioned in such a manner that they are spaced apart from each other and within the thermal break  38 . If the thermal break  38  is burned away or otherwise removed, such as shown in  FIG. 6 , the catch structures  72 ,  74  engage or otherwise mechanically interlock with each other in a manner such that the positioning of the exterior building components relative to the interior building components that are secured by the anchor  20  is maintained. 
     The following examples, illustrating the anchor  20  of the disclosure, are intended to illustrate and not to limit the invention. 
     EXAMPLES 
     Examples of the anchor are made by injection molding. Configuration of the anchors can be appreciated with reference to  FIG. 1 . A mold is configured to make 5 anchors at the same time. First and second ends are loaded into the mold. There are 5 pairs of the ends. The inner sides of the ends of each pair are spaced apart by about 0.25 inches (0.635 cm). Each end is a 1 inch (2.54 cm) T-bracket, and is formed from 304 stainless steel. A silicone composition is injected between the inner sides to form a thermal break between each pair of the ends. The thermal break adhesively couples each pair the ends together. The silicone composition is illustrated in Table I below.

     The silicone composition in Table I is classified as an addition cure silicone rubber typically cured using a platinum-based catalyst. The mold is heated to facilitate curing. After molding, the thermal breaks have a Shore A hardness of about 70 (ASTM D2240-05(2010)). The silicone rubber of the thermal break has excellent adhesive and cohesive strength. 
     The anchors can be used to form various assemblies for a structure. For example, if the exterior building component of a structure is subject to a windload of upwards of 50 pounds per square foot (2394.01 Pascal), one skilled in the art can determine the size and number of anchors required to achieve a desired wind load per anchor design. If an anchor is placed every 32 square feet (e.g. 8 feet×4 feet (i.e., approximately 2.44 meters×1.22 meters, or 2.97 square meters)), each anchor will be subject to about 1600 pounds wind load (7116.8 newtons). The single anchor would have to have a minimum breaking load of 6,400 pounds (about 28,467.2 newtons) for a 4:1 safety factor. For example, if the anchor has an ultimate breaking strength of 350 pounds per square inch (2.4 megapascals), the above-mentioned 4:1 safety factor would therefore require a 20 square inch cross-section (about 129 square centimeters). 
     It is to be understood that the appended claims are not limited to express and particular compounds, compositions, or methods described in the detailed description, which may vary between particular embodiments which fall within the scope of the appended claims. With respect to any Markush groups relied upon herein for describing particular features or aspects of various embodiments, it is to be appreciated that different, special, and/or unexpected results may be obtained from each member of the respective Markush group independent from all other Markush members. Each member of a Markush group may be relied upon individually and or in combination and provides adequate support for specific embodiments within the scope of the appended claims. 
     It is also to be understood that any ranges and subranges relied upon in describing various embodiments of the present invention independently and collectively fall within the scope of the appended claims, and are understood to describe and contemplate all ranges including whole and/or fractional values therein, even if such values are not expressly written herein. One of skill in the art readily recognizes that the enumerated ranges and subranges sufficiently describe and enable various embodiments of the present invention, and such ranges and subranges may be further delineated into relevant halves, thirds, quarters, fifths, and so on. As just one example, a range “of from 0.1 to 0.9” may be further delineated into a lower third, i.e., from 0.1 to 0.3, a middle third, i.e., from 0.4 to 0.6, and an upper third, i.e., from 0.7 to 0.9, which individually and collectively are within the scope of the appended claims, and may be relied upon individually and/or collectively and provide adequate support for specific embodiments within the scope of the appended claims. In addition, with respect to the language which defines or modifies a range, such as “at least,” “greater than,” “less than,” “no more than,” and the like, it is to be understood that such language includes subranges and/or an upper or lower limit. As another example, a range of “at least 10” inherently includes a subrange of from at least 10 to 35, a subrange of from at least 10 to 25, a subrange of from 25 to 35, and so on, and each subrange may be relied upon individually and/or collectively and provides adequate support for specific embodiments within the scope of the appended claims. Finally, an individual number within a disclosed range may be relied upon and provides adequate support for specific embodiments within the scope of the appended claims. For example, a range “of from 1 to 9” includes various individual integers, such as 3, as well as individual numbers including a decimal point (or fraction), such as 4.1, which may be relied upon and provide adequate support for specific embodiments within the scope of the appended claims. 
     The present invention has been described herein in an illustrative manner, and it is to be understood that the terminology which has been used is intended to be in the nature of words of description rather than of limitation. Many modifications and variations of the present invention are possible in light of the above teachings. The present invention may be practiced otherwise than as specifically described within the scope of the appended claims. The subject matter of all combinations of independent and dependent claims, both single and multiple dependent, is herein expressly contemplated.
