[0001] THERMALLY BROKEN ANCHOR AND ASSEMBLY INCLUDING THE SAME [0002]

Cross reference of related application

This application claims priority to U.S. Provisional Application No. 62 / 093,032, filed December 17, 2014, the contents of which are incorporated herein by reference.

Technical field

The present invention relates generally to an assembly for an anchor and a structure, and more particularly to an assembly including an anchor and interior and exterior building components, Is disposed between the components and has thermal breaks to reduce thermal bridging between the building components while the building components undergo a temperature difference between the building components.

In many commercial or industrial buildings, an L-bracket or a Z-bracket can be used to house an external building component (e.g., cladding) into an interior building component (e.g., a structural wall or a sub-frame ). ≪ / RTI > Consecutive lengths of span insulation often come into contact with at least the inner building component. The bracket passes through a seam in the insulation so that the outer component can be attached to the bracket that was previously attached to the inner building component. The brackets transfer the climactic load (e.g., wind load) of the environment from the outer building component to the inner building component. The brackets shall be strong enough to support the climate load and also the weight of the external building component (s). Thus, brackets are often formed from metal (e.g., steel or aluminum). Unfortunately, because the brackets described above are formed from metal, they serve as direct thermal shorts between exterior and interior building components. Various systems have been proposed in an effort to reduce heat transfer (i.e., heat loss or acquisition) between building components.

One system utilizes a ThermaStop (TM) thermal isolation system, available from Knight Wall Systems, Deer Park, Wash., USA. The ThermalStop ™ system uses 55 AL-ZN-coated steel brackets with plastic base and integral 1/8-inch plastic washers. Although the thermal stop system has a relatively narrow cross-section, this cross-section is formed from steel that passes through the insulation and acts as a direct thermal short-circuit.

Another system uses CASCADIA CLIP (registered trademark), available from Cascadia Windows Ltd., Langley, British Columbia, Canada. Cascadia Clip is a fiberglass girt spacer and is described in U.S. Patent D666,894 S and Bombino et al., U.S. Patent Application Publication No. 2013/0174506 A1 . Although formed from glass fibers, Cascadia Clips require conventional metal fasteners (e.g., lag screws) that serve as direct thermal shorts. In addition, the Cascadia Clip (registered trademark) may be difficult to install and time consuming.

Another system utilizes a thermal insulation material (TIM) available from FABREEKA (R), Boston, Mass., USA. The TIM is made from a fiberglass-reinforced laminate composite. Although formed from glass fiber, TIM is only a pad used between flanged steel connections. The steel connections shall be connected through conventional metal fasteners (eg bolts) which serve as direct thermal shorts. Also, TIMs can be difficult to install and time consuming.

Another system utilizes the POS-I-TIE TM ThermalClip TM available from Heckmann Building Products, Inc. of Melrose Park, Illinois, USA . The SEMAL clip is formed from polyphenylsulfone (PPSU), has a snap on design, and is described in U.S. Patent Application Publication No. 2013/0232909 A1 to Curtis et al. Seal Clip (registered trademark) is used for masonry construction. PPSU, but the Semar Clip (registered trademark) requires a conventional metal wire tie that can act as a direct thermal short circuit. In addition, Seal Clip (registered trademark) may be difficult to install and time consuming.

In view of the foregoing, there is still an opportunity to provide a system for reducing or eliminating heat transfer. Also, there is still an opportunity to provide a system that is easier to install and less time consuming.

An anchor is initiated. The anchor is useful for securing an exterior building component to an interior building component. The anchor includes a first end having an outer side for engaging the inner building component. The anchor also includes an inner side opposite the outer surface of the first end. The anchor further comprises a second end having an outer surface for engaging an outer building component. The anchor further includes an inner surface opposite the outer surface of the second end. The inner surfaces of the ends are directed towards each other. The space is defined between the inner surfaces of the ends. And the heat shielding portion is disposed in the space. The heat shield has a first coupling surface bonded to an inner surface of the first end. The heat shield also has a second coupling surface opposite the first coupling surface, which is joined to the inner surface of the second end. The thermal conductivity of the thermal barrier is lower than the thermal conductivity of at least one of the ends. Thermal breaks generally reduce thermal bridges between building components while building components undergo temperature differences between building components.

An assembly is also disclosed. The assembly includes interior and exterior building components that are spaced apart from each other to define a space. Anchors are placed between building components. Anchors anchor exterior building components to interior building components and generally reduce thermal bridges between them. The assembly is useful for structures, such as buildings.

A method is also disclosed. The method involves securing the outer building component to the inner building component. The method includes providing an anchor and attaching the anchor to one of the building components to form a sub-assembly. The method further includes the step of connecting the sub-assembly to the remaining building components to secure the building components.

Other advantages of the present disclosure will be readily appreciated as the disclosure will be better understood with reference to the following detailed description when considered in connection with the accompanying drawings.

Although the T-bracket configuration is shown, the second end 28 can have a variety of configurations and is not limited to any particular configuration. The second end 28 may 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 may be different from each other as shown in FIG.

The inner surfaces 26, 32 of the ends 22, 28 are generally facing one another. Typically, the inner sides 26 and 32 are substantially parallel to each other; This is not necessary. The space 34 is generally defined between the inner sides 26, 32 of the ends 22, 28. The space 34 may have various dimensions.

Other configurations, designs, or profiles that may be used for at least one of the ends 22 and 28 and / or for the anchor 20 itself include conventional L-brackets, Z-brackets, U-brackets, C - brackets, I-brackets, H-brackets, hanging-brackets, hat-brackets, stirrup-brackets, flat-brackets, split-bend-anchors -bend-anchor), and so on. The anchor 20 may be configured to replicate various types of conventional anchors used in structures for securing building components together. The anchor 20 may also be referred to as a tie, clip, or bracket. Those skilled in the art will be able to select the appropriate configuration of the ends 22, 28 and / or the anchor 20 based on the use, location, load, etc. of the anchor 20.

Alternatively, the ends 22, 28 may individually define at least one aperture 36. [ The apertures 36 may have various sizes, dimensions, and shapes. The hole 36 may be used to attach the first end 22 to the inner building component and / or to attach the second end 28 to the outer 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, and the like. The present disclosure is not limited to any particular type of fastener. The hole (s) 36 may be pre-formed or post-formed within the end (s) 22, 28 by, for example, casting, machining, stamping, drilling,

Typically, each of the ends 22,28 individually comprises 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 includes a metallic material. In these embodiments, each of the ends 22,28 may 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, and the like. In some embodiments, each of the ends 22,28 includes iron. In a particular embodiment, each of the ends 22,28 comprises steel. Various grades of steel (SAE Steel Grade) such as 200 or 300 series stainless steel can be used to form the ends 22, 28. In a particular embodiment, SAE steel 304 stainless steel is used to form each of the ends 22,28. Those skilled in the art will be able to select the appropriate material for each of the ends 22,28 based on the use, location, load, etc. of the anchor 20. [

A heat shield 38 is disposed in the space 34. The thermal cut-off portion 38 has a first coupling surface 40 that is joined to an inner surface 26 of the first end 22. The thermal cut-off portion 38 also has a second coupling surface 42 opposite the first coupling surface 40. The second coupling surface 42 is joined to the inner surface 32 of the second end 28.

Typically, the thermal cut-off portion 38 adhesively bonds the ends 22, 28 together. In other words, during normal use, the first coupling surface 40 is generally bonded to the inner surface 26 of the first end 22, and the second coupling surface 42 is generally bonded to the second end 28 To the inner surface 32 of the base material. Adhesion generally tends to cling to dissimilar surfaces. In a further embodiment, the thermal cut-off portion 38 exclusively bonds the ends 22, 28 together. In these embodiments, the anchor 20 has no supplemental means for connecting the ends 22, 28 together. In other words, the ends 22, 28 are attached together entirely by the thermal cut-off portion 38, and no further portions are added. Examples of such supplementary means include, but are not limited to, fasteners such as bolts, pins, screws, and the like.

The thermal cut-off portion 38 may have various dimensions. As best seen in FIG. 1B, the thermal cut-off portion 38 generally has a height H, a width W, and a thickness T. As shown in FIG. The height H, the width W, and the thickness T of each of the heat shields 38 may be uniform or different. A person skilled in the art can select an appropriate height H, width W and thickness T of the heat shielding portion 38 based on the use, position, load and the like of the anchor 20.

The thermal cut-off portion 38 may have various cross-sectional areas as generally defined by its height H and width W. [ In various embodiments, the heat intercepting portion 38 has a thickness of from about 1 to about 800, from about 1 to about 300, from about 1 to about 200, from about 5 to about 100, from about 5 to about 50, from about 10 to about 40, from about 20 (H * W) of any subrange of from about 1 to about 40, or about 30 square centimeters (cm2), or from about 1 to about 800 cm2. Alternatively, the thermal breaks 38 from about 0.5 to about 120 square inches (in ²⁾ (3.23 to 774 ㎠), from about 0.5 to about 80 in ² (3.23 to 516 ㎠), from about 2 to about 40 in ² (12.9 to 258 cm 2), about 2 to about 20 in ² (12.9 to 129 cm 2), about 4 to about 16 in ² (25.8 to 103.2 cm 2), about 8 to about 16 in ² (50.6 to 103.2 cm 2) (H * W) of about 12 in ² (77 cm 2), or any subranges from about 0.5 to about 120 in ² (3.23 to 774 cm 2). Those skilled in the art will be able to select the appropriate cross-sectional area (H * W) of the thermal cut-off portion 38 based on the use, location, load, etc. of the anchor 20.

The thermal cut-off portion 38 may have various average thicknesses as generally defined by its thickness T. [ In various embodiments, the heat intercepting portion 38 may comprise 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, 6 mm (mm), or an average thickness (T) of any subrange of from about 1 to about 40 mm. Alternatively, the thermal cut-off portion 38 may have a thickness of about 0.05 to about 2 inches (1.27 to 50.8 mm), about 0.05 to about 1.5 inches (1.27 to 38.1 mm), about 0.05 to about 1.25 inches (1.27 to 31.75 about 0.25 to about 0.5 in (6.35 to about 12.7 mm), or about 0.25 in (6.35 mm), and about 0.25 inches (6.35 mm), and about 0.05 to about 1 inch (1.27 to 25.4 mm) , Or an average thickness (T) in any subrange of from about 0.05 to about 2 in. (1.27 to 50.8 mm). Those skilled in the art will be able to select an appropriate average thickness T of the heat shield 38 based on the use, location, load, thermal performance requirements, etc. of the anchor 20.

Optionally, at least a portion of the thermal cut-off portion 38 may be molded over at least a portion of at least one of the ends 22,28. Although not required, it is believed that overmolding may be useful to increase the strength (e.g., sheer strength) of the anchor 20. Optionally, at least one of the inner surfaces 26, 32 of the ends 22, 28 may include one or more surface protrusions. Although not required, it is believed that the surface protrusions may be useful to increase the strength (e.g., shear strength) of the anchor 20. [ Surprisingly, it has been found that the strength of the anchor 20 is still adequate when the inner surfaces 26, 32 of the ends 22, 28 are substantially smooth (e.g., before placing or forming the heat barrier 38). Those skilled in the art can select appropriate options (e.g., overmolding and / or protrusions) based on the use, location, load, etc. of the anchor 20.

Heat shield 38 typically includes a rigid, semi-rigid, semi-flexible, or flexible material. It is believed that such material is capable of varying degrees of movement between the ends 22, 28 of the anchor 20. For example, certain amounts of settling, flexing, expansion, and / or shrinkage can occur in a given building component. External building components tend to move especially when subjected to climate loads (e.g., wind loads) and / or temperature variations (e.g., when exposed to sunlight on cool / cold days). Other types (or types) of loads include dead load, live load, building load, environmental load, and gravity load, and the disclosure is not limited to a specific load.

Typically, the thermal cut-off portion 38 is formed from a material that is different from at least one of the ends 22, 28, and more typically, is different from both ends 22, 28. In various embodiments, the thermal cut-off portion 38 comprises a polymeric material. Various types of polymer chemistries including, but not limited to, elastomers (or rubbers), silicon or silicone rubbers, or rigid materials such as epoxy or epoxy adhesives can be used to form the thermal barrier 38.

In various embodiments, the thermal cut-off portion 38 comprises an elastomer (or rubber). Examples of suitable elastomers include, but are not limited to, thermoplastic elastomers (TPE), unsaturated rubbers, saturated rubbers, and mixtures thereof.

Specific examples of suitable TPE include, but are not limited to, styrene block copolymers, polyolefins, elastomeric alloys, polyurethanes, copolyesters, and polyamides. Mixtures of TPE may also be used. In certain embodiments, the thermal cut-off portion 38 is formed from a polyurethane (e.g., 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 polyisoprene, polybutadiene, chloroprene, butyl rubber, styrene-butadiene, and nitrile rubber. The predetermined unsaturated rubber can also be cured by means other than sulfur vulcanization. Mixtures of unsaturated rubbers may also be used.

Specific examples of suitable saturated rubbers are ethylene propylene rubber (EPM), ethylene propylene diene rubber (EPDM), epichlorohydrin rubber, polyacryl rubber, silicone rubber, fluorosilicone rubber, fluoroelastomer, perfluoroelastomer But are not limited to, polymers, polyether block amides, chlorosulfonated polyethylene, and ethylene-vinyl acetate. Mixtures of saturated rubbers may also be used. In some embodiments, the thermal cut-off portion 38 is formed from EPDM.

In various embodiments, the thermal cut-off portion 38 comprises silicon. In a further embodiment, the thermal cut-off portion 38 comprises a silicone rubber. The silicone rubber may also be referred to as a silicone elastomer. Various types of silicone rubbers may be used to form the thermal cut-off portion 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. Thermal curing systems typically require additional cure mechanisms or peroxide cure mechanisms using platinum-based catalysts to facilitate cure. The curing process can be accelerated by adding heat and / or pressure. Examples of suitable silicone rubbers include, but are not limited to, SILASTIC TM Silicone Rubber (e.g., Silastic TM TR-70 Silicone Rubber), Dow Corning, Midland, Mich. Corporation).

Alternatively, the thermal cut-off portion 38 is formed from a condensation-curable silicone structural adhesive or a condensation-curable silicone structural sealant which forms an elastomeric material suitable for curing. Examples of suitable silicone structural adhesives or condensation-curable silicone structural sealants include those available from Dow Corning Corporation of Midland, Mich., Such as Dow Corning Silicone Structural Sealant Corning < (R) > 995 Silicone Sealant Sealant).

In various embodiments, the thermal cut-off portion 38 comprises an epoxy or epoxy adhesive. In certain of these embodiments, the epoxy or epoxy adhesive is cured to provide sufficient adhesion and desired adhesion strength to the respective inner surfaces 26, 32 of the first and second ends 22, 28 during use To form a rigid material.

In embodiments where the thermal cut-off portion 38 comprises a polymeric material such as an elastomer, silicone or epoxy, the thermal cut-off portion 38 generally has a very low thermal conductivity. For example, the thermal cut-off portion 38 may have a thermal conductivity of less than 2, 5, 10, 25, 50, or 100 times that of a metallic material such as steel. The heat shield 38, and thus the anchor 20, can be configured to have fail safe flame resistance. For example, the anchor 20 may be configured to have mechanical catches that will allow the ends 22, 28 to maintain structural engagement when a fire destroys the polymer thermal shut-off portion 38. This is a standard fire test method for evaluating the fire propagation characteristics of NFPA 285 (National Fire Protection Association Test 285 - External Non-Load-Support Wall Assemblies including combustible components, Available from NFPA, Quincy, Calif.)). The anchor 20 may also be configured to withstand "freeze-thaw" conditions and / or be configured to withstand alkaline materials in the mortar.

The anchor 20 can be manufactured by various manufacturing methods, and the present disclosure is not limited to a specific manufacturing method. In some embodiments, the anchor 20 is made by injection molding. In these embodiments, the material (e.g., a silicone composition) used to form the thermal cut-off portion 38 is injected between the ends 22, 28 in a state of being in the mold. Heat and / or pressure can be used to accelerate the curing of certain materials, such as silicone rubber. Other molding methods such as compression molding can also be used. A person skilled in the art can select an appropriate manufacturing method based on the material used to form the anchor 20.

Assembly (each shown as 50 in an alternate embodiment of Figures 3-6). The assembly 50 is useful for construction and can be used in the construction industry. The structure is typically a building, and the present disclosure is not limited to any particular structure. Examples of buildings include, but are not limited to residential, commercial, and industrial buildings such as single story, mid-rise, and high-rise buildings.

Assembly 50 includes interior building components (each shown as 48 in Figures 3-6). The inner building component 48 may be any type of conventional inner building component, and this disclosure is not limited to any particular inner building component. Examples of suitable interior building components include studs, beams, rails, joists, ties, trusses, mounts, braces, frames, walls, and / But are not limited to, a support. The inner building component may include one or more of the foregoing examples.

The assembly 50 further includes outer building components (shown as 46 in Figures 3-6, respectively) that are spaced from the inner building component 48. The outer building component 46 may be any type of conventional outer building component, and this disclosure is not limited to any particular outer building component. Examples of suitable exterior building components include rain screens, curtain walls, bricks, masonry, stone, timber, panel, siding, but are not limited to, siding, facade, cladding, gut, rail, wall, sill, lintel, header, and mullion. The exterior building components may include one or more of the foregoing examples. The examples listed above for internal and external building components are not all inclusive. Also, what is described as an inner building component can also be used as an outer building component and vice versa. This disclosure is not limited to the specific designation of building components.

The assembly 50 further includes an anchor 20 as described above in FIGS. 1 and 2. The anchor 20 is disposed between the inner building component 48 and the outer building component. The anchor 20 generally secures the outer building component 46 to the inner building component 48 (or vice versa).

Optionally, the assembly 50 may further include one or more conventional building components. This disclosure is not limited to any particular type or number of conventional building components. In various embodiments, the assembly further includes at least one fastener. Examples of suitable fasteners include, but are not limited to, bolts, screws, pins, nails, rivets, adhesives, and the like. The present disclosure is not limited to any particular type of fastener. When used, fasteners are generally used in conjunction with holes 36. [ Also, if used, the fastener 36 generally does not operatively connect the ends 22, 28 together, for example by running across the ends 22, 28.

In various embodiments, the assembly 50 further includes a thermal insulation. The insulation may be disposed about 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, batt and blanket, loose-fill insulation, structural insulated panel (SIP), spray foam, vacuum insulation panel vacuum insulated panel, VIP), and the like. Further examples of suitable types of insulation include, but are not limited to, glass fibers, mineral wool, glass wool, rock wool, cotton, expanded polystyrene (EPS), extruded polystyrene , XPS), polyisocyanurate ("polyisso"), open-cell or closed-cell polyurethane foam, cellulose, aerogels and the like. Optionally, one or more fasteners such as a stick pin, clip, etc. may be used to hold the insulation in place. The present disclosure is not limited to any particular type of insulation or its fastener.

The thermal conductivity of the thermal barrier 38 is lower than the thermal conductivity of at least one of the ends 22,28. In certain embodiments, the thermal conductivity of the thermal cut-off portion 38 is lower than the thermal conductivity of each (or both) of the ends 22,28. The thermal barrier 38 may also be referred to as a thermal barrier. The lower thermal conductivity of the thermal shutdown 38 generally reduces thermal bridging between building components while the interior and exterior building components undergo a temperature differential between the building components. Generally, the thermal cutoff 38 reduces or prevents the flow of heat energy between the ends 22, 28, thereby reducing the flow of heat energy (or heat transfer) between the interior and exterior building components . The present disclosure is not limited to a particular direction of heat energy flow (e.g., inward, outward, or neutral).

Thermal bridges (also referred to as cold bridges or thermal shorts) can be used to prevent the penetration of the insulating layer by highly conductive or non-insulating material into the building assembly (also referred to as a building enclosure) (Or an air conditioned space) of a building envelope, a building envelope, or a thermal envelope, and a separation between external environments. The thermal bridging phenomenon is such that even though adjacent layers of the material separated by the insulation and / or the air space allow little heat transfer, materials which are not good thermal insulators come into contact, And is allowed to flow through the path. For example, a sun shade fixed to a side of a building typically passes through the insulation, and their fixation creates a thermal bridge to the interior of the building.

In general, the insulation around the thermal bridge is of little help in preventing heat loss or acquisition due to thermal bridges. By way of example, a balcony can serve as a "cooling fin " if the thermal bridge on the balcony of the building is not being treated. Such cooling fins conduct heat away from the building and cool the room adjacent to the balcony. A wall with a thermal bridge can resemble a bucket with a hole in it. Adding insulation without blocking heat bridges is like increasing the wall thickness of the bucket without blocking the holes. In various embodiments using the insulation, the only part that interrupts the insulation layer is the thermal barrier 38. In this way, for example, a foam wall board can be used in a manner that provides true continuous insulation.

A method is also disclosed. The method is useful for securing the outer building component 46 to the inner building component 48. The method includes providing an anchor (20). The method further includes attaching the anchor (20) to one of the building components to form a sub-assembly. For example, the anchor 20 may be attached to the inner building component 48 or to the outer building component 46 to form a sub-assembly.

The method further includes the step of connecting the sub-assembly and the remaining building components to secure the outer building component (46) to the inner building component (48). For example, an outer building component 46 may be attached to a sub-assembly comprising an anchor 20 and an inner building component 48. Conversely, an inner building component 48 may be attached to a sub-assembly comprising an anchor 20 and an outer building component 46. One or more fasteners may be used for such attachment.

One or more anchors 20 may be used to attach the building components 46, 48 of the structure. Those skilled in the art can select an appropriate number of anchors 20 based on the use, position, load, and the like of the anchor 20. The same is true for determining the size, configuration, and position of the anchor 20. The anchor 20 should be of sufficient size to support the outer building component 46 from both the climate and gravity loads. The anchor 20 can be designed based on the final application. In some embodiments, the anchor 20 and / or the assembly 50 may be fire safe by including additional mechanical clips that engage when the polymer thermal barrier material 38 is lost during a fire and when it is lost. , Where such a system can be verified by testing against NFPA 285. < RTI ID = 0.0 >

Referring to Figure 3, a photograph of a portion of the assembly 50 is illustrated as having an outer building component 46, an inner building component 48, a clip 56, and a rigid foam insulation 60. The assembly 50 is just one example of a possible configuration of an assembly in which the anchor 20 of the present disclosure can be used instead of, or in addition to, the clip 56, for example.

Figure 4 shows an anchor 20 according to Figure 2, disposed between an outer building component 46 and an inner building component 48 to secure the outer building component 46 to the inner building component 48. [ Lt; RTI ID = 0.0 > 50 < / RTI >

In Figure 4, the outer surface 24 of the first end 22 of the anchor 20 is positioned against the outer surface 156 of the outer building component 46. A fastener 165 shown here as a screw 165 is inserted through each hole 36 to secure the second end 28 to the outer building component 46. An additional fastener 165 is also inserted through the hole 36 in the second end 28 to secure the inner building component 48 to the second end 28.

As also illustrated in FIG. 4, a thermal cutoff 38 is disposed within the space 34 between the first end 22 and the second end 28.

The following examples illustrating the anchor 20 of the present disclosure are intended to be illustrative rather than limiting.

Yes

Examples of anchors are produced by injection molding. The configuration of the anchor can be recognized with reference to Fig. The mold is configured to simultaneously produce five anchors. The first and second ends are loaded into the mold. There are five pairs of 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 surfaces to form a thermal barrier between each pair of ends. The heat shields adhesively couple each pair of ends together. The silicone composition is illustrated in Table I below.

[Table I]

The silicone compositions of Table I are typically classified as addition curing silicone rubbers that are cured using a platinum-based catalyst. The mold is heated to facilitate curing. After molding, the thermal cut-off has a Shore A hardness of about 70 (ASTM D2240-05 (2010)). The silicone rubber of the heat shielding part has excellent adhesion and cohesive strength.

The anchor can be used to form various assemblies for the structure. For example, when an exterior building component of a structure receives a wind load of 50 pounds per square foot (2394.01 pascal) or more, one skilled in the art can determine the size and number of anchors needed to achieve the desired wind load according to the anchor design. If an anchor is placed every 32 square feet (e.g., 8 feet x 4 feet (i.e., about 2.44 meters x 1.22 meters, or 2.97 square meters), each anchor will receive a wind load of about 1600 pounds (7116.8 Newtons). A single anchor will 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 fracture strength of 350 pounds per square inch (2.4 megapascals), the above-mentioned 4: 1 safety factor will accordingly require 20 square inches (about 129 square centimeters) cross section.
