AI Technical Summary
Existing temperature-controlled shipping containers face challenges with durability, reusability, and cost-effectiveness, particularly in active and passive containers, due to the limitations of insulative materials and assembly methods.
A durable polymer coating is applied to the panel assemblies of a collapsible container, enhancing their scratch, scuff, and impact resistance, allowing for repeated use and easy refurbishment, while maintaining thermal performance and reducing damage.
The durable polymer coating ensures the container's longevity and reusability, minimizing damage and repair time, and reducing shipping and repositioning costs, while maintaining temperature control for sensitive goods.
Abstract
Description
TEMPERATURE CONTROL TRANSPORT CONTAINER WITH DURABLE POLYMER COATINGAPPLICATION FIELD
[0001] This application relates generally to cold chain or temperature-controlled shipping, and more specifically to cold chain shipping.BACKGROUND
[0002] Various high value items are required to be shipped (preferably by air freight or container for both ocean and land transportation) within a temperature-controlled container. These high value items may include medicines (e.g., vaccines, organic compositions, individually developed treatments, and / or perishable medical material), food & beverage (e.g., seafood, spices, meat, yeast, and / or easily perishable edibles, diary, alcohol, etc.), and / or plants (e.g., flowers and / or seeds). For bulk loads, pallet sized loads, and other similarly sized loads, larger insulated shipping containers may include insulating features to minimize loss due to ambient conditions.
[0003] Generally, there are two types of containers: active containers and passive containers. Active containers actively control a shipping container’s cargo temperature, and include an electronic means to sense the temperature of the cargo bay. Autonomous control system directs heating and cooling actuators and associated systems maintain and correct for temperature deviations. Passive systems generally incorporate pre-conditioned material for thermal capacitance. These pre-conditioned materials may include phase change materials (PCM) for latent capacity of non PCM materials for sensible capacity, PCM mediums can also include dry ice (DI). The efficacy is related to performance, duration, and weight. Performance attributes include proper regulation of the cargo temperature over various shapes and sizes of cargo, overcoming loss due ambient exposure of the container (both environmental and radiated), and uniformity of thermal regulation over the volume and geometry of the load. Adequate duration is desirable based on the anticipated period of transportation. Weight contributes significantly to freight costs.
[0004] Collapsible insulative shipping systems have a limited lifecycle due to properties of the insulative materials the outer panel assemblies are made from. Rigid container insulative shipping systems are far more durable with outer skins constructed of materials such as aluminum. While rigid container insulative shipping systems offer repeated reusability, they are heavy and costly to ship and reposition after use. Additionally, damage is costly and time consuming to repair putting the whole system out of service until complete. Challenges include a robust and straightforward method of assembly and adhesion, accuracy and repeatability, weight, durability, material cost and supply, manufacturing time, and recyclability.
[0005] As a result, it is desirable to produce a durable collapsible container that is capable of being repeatedly reused.BRIEF DESCRIPTION OF THE DRAWINGS

[0033] I. Example of Temperature Control Transport Container
[0034] A. Overview
[0035] FIGS. 1-2 show an example of a temperature control transport container (10). Container (10) includes a plurality of panel assemblies, which are shown as two end panel assemblies (12), two side panel assemblies (14), a top panel assembly (16), and a bottom panel assembly (18). However, more or fewer panel assemblies (12, 14, 16, 18) are envisioned. Panel assemblies (12, 14, 16, 18) are configured to be converted by a user between an assembled configuration (see FIG. 1) and a non-assembled configuration (see FIG. 15). In the assembled configuration, end panel assemblies (12) are disposed opposite each other. Similarly, side panel assemblies (14) are disposed opposite each other and extend between end panel assemblies (12). End and side panel assemblies (12, 14) are disposed between top panel assembly (16) and bottom panel assembly (18) to collectively enclose container (10) in the assembled configuration. Container (10) may be repeatedly reused (e.g., about 2-10 times), and may optionally include minor refurbishment between successive uses.
[0036] As shown in the exploded perspective view of FIG. 2, container (10) includes sensors (20), temperature stabilization modules (22), load spreaders (24), load separators (26), corner protectors (28), edge protectors (30), and temperature sensitive product (32) arranged on a product pallet (34). In the assembled configuration of FIG. 1, panel assemblies (12, 14, 16, 18) collectively define a volume configured to receive temperature sensitive product (32). Temperature stabilization modules (22) may include aqueous-based petrochemical, organic and inorganic PCM mediums. Temperature stabilization modulesachieve absorb and / or release energy by changing states or phases, most commonly from a solid to a liquid, although sublimation can effectively mean a medium skips a phase change stage. Temperature stabilization modules (22) may be used to maintain a product temperature range of about -90°C to about -60°C (ultra low), about -60°C to about -40°C (deep frozen), about -20°C to about -30°C (frozen), about 2°C to about 8°C (chilled), or about 15°C to about 25°C (control room temperature). Temperature stabilization modules (22) may provide other temperature levels and ranges if desired. Water goes through the liquification / solidification phase change at 0°C which is a few degrees colder than one exemplary temperature for shipping temperature sensitive goods with a temperature range of about 2°C to about 8°C, to counteract the cooling effect, sensible heat is added to the latent heat. Non-aqueous based temperature stabilization modules have an engineered phase change point at the desired product temperature (i.e., about 5°C for chilled shipments).
[0037] Container (10) transports product pallet (34) of temperature sensitive product (32) and maintains a desired product temperature for a duration of up to 120 hours. Temperature sensitive product (32) may include pharmaceutical, food, beverage and / or chemical products. The desired temperature may vary depending on the temperature sensitive product (32) contained within container (10). While container (10) is sized and configured to protect a pallet side load of temperature sensitive product (32), container (10) may have other sizes suitable for smaller loads or larger loads and / or for various other durations of time. Load spreaders (24) and load separators (26), are shown as extruded polypropylene and polycarbonate sheets; however, other materials for load spreaders (24) are also envisioned. Nine temperature stabilization modules (22), arranged in three rows of three, are disposed between bottom panel assembly (18) and lower load spreader (24), and eighteen temperature stabilization modules (22) are disposed between upper load spreader (24) and top panel assembly (16) arranged in two layers with each layer being three rows of three. However, more or fewer temperature stabilization modules (22) are envisioned. Load separators (26) separate the three rows. As shown in FIG. 2, panel assemblies (12, 14, 16, 18) may include an optional vacuum insulated panels (VIPs) (38). While each panel assembly (12, 14, 16, 18) is shown as including VIP (38), VIPs (38) may be included in some or none of panel assemblies (12, 14, 16, 18).
[0038] As will be described in greater detail, a durable polymer coating (36, 36a) may be applied to select portions of panel assemblies (12, 14, 16, 18) or an entirety of individual panel assemblies (12, 14, 16, 18). Panel assemblies (12, 14, 16, 18) with durable polymer coating (36, 36a) are intended to be scratch, scuff, impact, and chemical resistant. For example, panel assemblies (12, 14, 16, 18) are sufficiently durable to be repeatedly reused. Panel assemblies (12, 14, 16, 18) are configured to be easily inspected, repaired if needed, or discarded if desired. Durable polymer coating (36, 36a) may increase the durability of panel assemblies (12, 14, 16, 18) during shipping, usage and return of container (10) to maintain the thermal and mechanical properties of panel assemblies (12, 14, 16, 18).
[0039] As shown, each panel assembly (12, 14, 16, 18) includes a unique electronic identifier (39) that is different for each panel assembly (12, 14, 16, 18). For example, a first end panel assembly (12) includes a first unique electronic identifier (39), and second end panel assembly (12) includes a second unique electronic identifier (39). Likewise, a first side panel assembly (14) includes a third unique electronic identifier (39), and a second side panel assembly (14) includes a fourth unique electronic identifier (39). Top panel assembly (16) includes a fifth unique electronic identifier, and bottom panel assembly (18) includes a sixth unique electronic identifier (39). Unique electronic identifier (39) may include a Radio Frequency Identification (RFID) tag. Alternatively, unique electronic identifier (39) may include a Near Field Communication (NFC) tag, a low energy device such as a Bluetooth Low Energy (BLE) device, or a cellular device. RFID and NFC rely on radio frequency for communication purposes, whereas BLE utilizes the 2.4 GHz ISM band for field communication. RFID may be used for long-range applications, whereas NFC may be used for short-range applications. Each RFID tag, NFC tag, and / or BLE device may be positioned entirely within one of panel cores (40, 78, 106, 120) that includes durable polymer coating (36, 36a) as shown and described below. Unique electronic identifier (39) allows for tracking on a panel assembly by panel assembly basis.
[0040] B. Example of End Panel Assembly
[0041] As shown in FIGS. 2-3, each end panel assembly (12) includes an end panel core (40), a flexible holder (42), a liner member (44), and a data logger assembly (46). End panel core (40) includes an inner surface (48), an outer surface (50), and an edge (52)extending between inner and outer surfaces (48, 50). Edge (52) includes an outer portion (53) and an inner portion (55). Outer portion (53) is perpendicular inner and outer surfaces (48, 50), and inner portion (55) is mitred and may function as a sealing surface. At least outer surface (50) of end panel core (40) includes durable polymer coating (36). Outer surface (50) extends outwardly away from temperature sensitive product (32), and inner surface (48) extends inwardly toward temperature sensitive product (32). While first panel assembly is shown and described as end panel assembly (12), it is envisioned that first panel assembly may alternatively be one of side panel assemblies (14), top panel assembly (16), or bottom panel assembly (18). As will be described in greater detail with reference to FIG. 8-11, end panel core (40) includes a recessed portion (60) configured to receive data logger assembly (46). Data logger assembly (46) includes a data logger (62), a flexible insert (64), and an exterior data logger cover (66). Data logger (62) is positioned within recessed portion (60) of end panel core (40) includes durable polymer coating (36) and is protected by exterior data logger cover (66). Data logger (62) is in communication with sensor (20) and may be in communication with optional unique electronic identifier (39).
[0042] End panel core (40) is in direct contact with durable polymer coating (36). As shown, durable polymer coating (36) is in direct contact with and covers an entirety of end panel core (40). In other words, inner surface (48), outer surface (50), and edge (52) are each covered with durable polymer coating (36). End panel core (40) includes at least one of expanded polystyrene, extruded polystyrene, expanded polypropylene, or polyurethane. For example, end panel core (40) may include expanded polystyrene with a graphite additive. At least one optional VIP (38) may be embedded within end panel core (40), or alternatively may be inserted into or operatively coupled with end panel assembly (12). For example, VIP (38) may be positioned on inner surface (48) of end panel core (40). A portion of surface area of VIP (38) may include durable polymer coating (36). In some versions, an entirety of the outer surface area of VIP (38) includes durable polymer coating (36).
[0043] Flexible holder (42) includes a cavity (54) is configured to retain at least one temperature stabilization module (22) therein. As shown, cavity (54) of flexible holder (42) receives two rows of four temperature stabilization modules (22) within each row.Flexible holder (42) is removably coupled with end panel core (40) and is detachable for refurbishment or replacement. Flexible holder (42) is removably coupled with end panel core (40) using hook and loop fasteners; however, other coupling methods are also envisioned including adhesive and / or fasteners. Hook and loop fasteners are commercially available from Velcro IP Holdings LLC. For example, end panel core (40) may include a first portion (70) of hook and loop fasteners, and flexible holder (42) may include a second portion (72) of hook and loop fasteners. For example, first portion (70) may be the hook portion, and second portion (72) may be the loop portion. In some versions, flexible holder (42) may be formed from corrugated plastic (e.g., corrugated polypropylene). Liner member (44) may include an optional cover (56). In some versions, optional cover (56) is formed from molded acrylonitrile butadiene styrene (ABS). Liner member (44) includes a sensor holder (58) configured to fix the position of sensor (20) to ensure consistent measurements of sensor (20), which may be a temperature sensor configured to measure the temperature of the internal volume of container (10).
[0044] C. Example of Side Panel Assembly
[0045] FIG. 4 shows an enlarged exploded perspective view of side panel assembly (14), corner protectors (28), and edge protectors (30) of FIG. 2. As shown, each side panel assembly (14) includes a side panel core (78), a flexible holder (80), a liner member (82), and handles (84) (see FIG. 1). Flexible handles (84) are shown as being positioned adjacent edges of side panel assemblies (14). While six handles (84) are shown in FIG. 1, more or fewer handles (84) are envisioned. For example, FIG. 2 shows top panel core (106) and side panel cores (78) each including handles (84).
[0046] Side panel core (78) includes an inner surface (86), an outer surface (88), and an edge (90) extending between inner and outer surfaces (86, 88). At least outer surface (88) of side panel core (78) includes durable polymer coating (36). Outer surface (88) extends outwardly away from temperature sensitive product (32), and inner surface (86) extends inwardly toward temperature sensitive product (32). Edge (90) includes an inner portion (92) and an outer portion (94). Outer portion (94) includes first and second lateral rebate portions (96, 98) configured to abut edges (52) of adjacent end panel cores (40) of end panel assemblies (12) in the assembled configuration. End panel cores (40) do not includefirst and second lateral rebate portions (96, 98). However, end panel cores (40) may include first and second lateral rebate portions (96, 98) instead of side panel core (78). Inner portion (94) is mitred and may function as a sealing surface.
[0047] Side panel core (78) may be coupled with corner protectors (28) and / or edge protectors (30) prior to or after the application of durable polymer coating (36) to side panel core (78). In some versions, side panel core (78) is coupled with comer protectors (28) prior to the application of durable polymer coating (36) and side panel core (78) is coupled with edge protectors (30) after the application of durable polymer coating (36) to side panel core (78). Corner protector (28) may be included at comers of adjacent panel assemblies (12, 14, 16, 18). Comer protectors (28) and / or edge protectors (30) may be adhered to or within durable polymer coating (36) to offer increased strength at predetermined locations of container (10). Comer protectors (28) and / or edge protectors (30) protect container (10) from potential damage associated with users dragging and / or pivoting container (10) on corners. Coating a specific panel core (40, 78, 106, 120) together with corner protector (28) and / or edge protector (30) further increases the protection provided and reduces the likelihood that comer protector (28) and / or edge protector (30) are inadvertently broken off. Durable polymer coating (36) may permanently couple one or more corner protectors (28) and / or one or more edge protectors (30) with specific panel cores (40, 78, 106, 120).
[0048] Corner protectors (28) may be formed from plastic, paperboard, and / or metal. Edge protectors (30) may be formed form plastic, paperboard, and / or metal. For example, edge protectors (30) may consist of extruded plastic, which may be rigid or flexible. Edge protector (30) may be coupled (e.g., adhered using adhesive) with two adjoining panel assemblies, edge protector (30) is configured to protect lateral edges of panel assemblies (12, 14, 16, 18).
[0049] Durable polymer coating (36) may bond variations of insulative materials together to form a robust panel assembly (12, 14, 16, 18). Components added to the coated panel assembly (12, 14, 16, 18) to be easily detachable whether permanently or temporarily to aid the speed of refurbishment of panel assembly (12, 14, 16, 18) or to increase the lifecycle of panel assembly (12, 14, 16, 18) by replacement of less durable components, which may only be used once (i.e., single use components). Flexible holder (80) is removably coupledwith side panel core (78). For example, inner surface (86) of side panel core (78) may include a first portion (100) of hook and loop fasteners, and flexible holder (80) may include a second portion (102) of hook and loop fasteners; however, this may vary. Flexible holder (80) includes a cavity (104) configured to retain at least one temperature stabilization modules (22) therein.
[0050] D. Example of Top Panel Assembly
[0051] FIG. 5 shows an enlarged exploded perspective view of top panel assembly (16), corner protectors (28), and edge protectors (30) of FIG. 2. Top panel assembly (16) includes a top panel core (106) that may be coupled with corner protectors (28) and / or edge protectors (30) prior to the application of durable polymer coating (36). Top panel core (106) includes an inner surface (108), an outer surface (110), and an edge (112) extending between inner and outer surfaces (108, 110). At least outer surface (110) of top panel core (106) includes durable polymer coating (36). Outer surface (110) extends outwardly away from temperature sensitive product (32), and inner surface (108) extends inwardly toward temperature sensitive product (32). Edge (112) includes an outer portion (114), an intermediate portion (116), and an inner portion (118). Outer portion (114) is perpendicular to inner and outer surfaces (108, 110). Intermediate portion (116) extends parallel to inner and outer surfaces (108, 110) and is positioned between outer and inner portions (114, 118). Inner portion (118) is mitred and may function as a sealing surface.
[0052] E. Example of Bottom Panel Assembly
[0053] FIG. 6 shows an enlarged perspective view of bottom panel assembly (18) including a pallet (122). Top panel assembly (16) includes a bottom panel core (120) that may be operatively coupled with pallet (122) prior to the application of durable polymer coating (36). Similar to top panel core (106), bottom panel core (120) includes an inner surface (124), an outer surface (126), and an edge (128) extending between inner and outer surfaces (124, 126). At least outer surface (126) of bottom panel core (120) includes durable polymer coating (36). Outer surface (126) extends outwardly away from temperature sensitive product (32), and inner surface (124) extends inwardly toward temperature sensitive product (32). Edge (128) includes an outer portion (130), an intermediate portion(132), and an inner portion (134). Outer portion (130) is perpendicular to inner and outer surfaces (124, 126). Intermediate portion (132) extends parallel to inner and outer surfaces (124, 126) and is positioned between outer and inner portions (130, 134). Inner portion (134) is mitred and may function as a sealing surface.
[0054] Pallet (122) includes a raised outer lip (136) configured to receive end panel cores (40) and side panel cores (78). Raised outer lip (136) of pallet (122) together with intermediate portion (132) and inner portion (134) of bottom panel assembly (18) collectively define a rebate channel (138) see FIG. 19) configured to receive edge (52) of end panel assemblies (12) and edge (90) of side panel assemblies (14) in the assembled configuration. In some versions, pallet (122) may have a thickness of about 6 mm.
[0055] F. Examples of Durable Polymer Coatings
[0056] FIG. 7A shows a schematic sectional view of durable polymer coating (36) applied to end panel core (40) of end panel assembly (12) of FIG. 4. Durable polymer coating (36) is applied to inner surface (48), outer surface (50) and edge (52) of end panel core (40) as a single layer. In some versions, a portion of each panel assembly (12, 14, 16, 18) includes durable polymer coating (36). In some versions, the thickness of durable polymer coating (36) varies depending on the risk of potential damage to that particular surface. Single layer (140) of durable polymer coating (36) has a first maximum thickness (Tl) on outer surface (50) of end panel core (40) and a second maximum thickness (T2) on inner surface (48) of end panel core (40). Second maximum thickness (T2) is less than first maximum thickness (Tl). As shown moving inwardly toward temperature sensitive product (32), end panel assembly (12) includes durable polymer coating (36) with first maximum thickness (Tl), end panel core (40), durable polymer coating (36) with second maximum thickness (T2), first portion (70) of hook and loop fasteners, second portion (72) of hook and loop fasteners, an outer wall of flexible holder (42), cavity (54) receiving temperature stabilization modules (22), an inner wall of flexible holder (42), liner member (44), and sensor holder (58) coupled with sensor (20). Durable polymer coating (36) may include a polyurea coating having a thickness of about 0.5 millimeter to about 3.0 mm. However, other durable polymer coatings (36) are also envisioned including polyurea, polycarbonate, polyurethane, polyether, polyester, epoxy resin, nylon, and acrylic.
[0057] FIG. 7B shows a schematic sectional view of another example where multiple layers of durable polymer coating (36a) are applied to end panel core (40a) of end panel assembly (12a) of FIG. 3. Durable polymer coating (36a) includes first and second layers (142, 144) on outer surface (50) of end panel core (40). Data logger (62) is configured to communicate with sensor (20). Each sensor (20) is configured to sense at least one condition of temperature control transport container (10). It is beneficial to know the position and / or condition of container (10), including at an individual panel assembly level (RFID and / or GPS). As shown moving inwardly toward temperature sensitive product (32), second layer (144) of durable polymer coating (36a) with a third thickness (T3), first layer (142) of durable polymer coating (36a) with second thickness (T2), end panel core (40) including sensor (20) and unique electronic identifier (39), first layer (142) of durable polymer coating (36a) with a first thickness (T2), first portion (70) of hook and loop fasteners, second portion (72) of hook and loop fasteners, an outer wall of flexible holder (80), cavity (104) receiving temperature stabilization modules (22), an inner wall of flexible holder (80), liner member (44), and sensor holder (58) coupled with sensor (20).
[0058] It is desirable to minimize damage (e.g., cracks and / or holes) to panel assemblies that may affect insulative qualities of container (10). Outer surfaces (50, 88, 110, 126) of panel assemblies (12, 14, 16, 18) are protected during use to resist shipping damages. Outer surfaces (50, 88, 110, 126) of panel assemblies (12, 14, 16, 18) generally encounter the most wear and potential damage during use. Multiple mechanical handling points, including road transport, air transport, and / or mechanical handling machinery such as forklift trucks during loading and unloading may cause damage. Inner surfaces (48, 86, 108, 124) face experience wear and tear during assembly, disassembly, and flat packing. Container (10) may be manually handled during assembly and disassembly. Durable polymer coating (36, 36a) ensures that panel assemblies (12, 14, 16, 18) do not sustain damage when being stacked flat after use and returned for reuse. Durable polymer coating (36) protects panel assemblies (12, 14, 16, 18) during the process of stacking and storing panel assemblies (12, 14, 16, 18) during disassembly and preserves the integrity of panel assemblies (12, 14, 16, 18) during return to a service center to be prepared for reuse. After disassembly, each panel assembly (12, 14, 16, 18) is separate, and therefore, vulnerable to damage on inner surfaces (48, 86, 108, 124), outer surfaces (50, 88, 110, 126), internal andedge seals. Durable polymer coating (36, 36a) protects edges (52, 90, 112, 128) of panel assemblies (12, 14, 16, 18) from sustaining damage (including cracks, dents or pieces to be broken away). Protecting edges (52, 90, 112, 128) of panel assemblies (12, 14, 16, 18) maintains thermal performance and sealing of container (10).
[0059] As a result, it may be desirable to coat one or more panel assemblies (12, 14, 16, 18) in a non-uniform manner, which allows durable polymer coating (36, 36a) to provide adequate durability while minimizing the additional weight due to the durable polymer coating (36). Different surfaces may have differing layers and / or different thicknesses to provide the desired level of protection. For example, outer surfaces (50, 88, 110, 126) may have about a 2 millimeter thickness to withstand external impacts, whereas inner surfaces (48, 86, 108, 124) may have about a 1 millimeter thickness due to the likelihood of fewer impacts. Edges (52, 90, 112, 128) may have a durable polymer coating thickness of about 0.5 millimeters.
[0060] Durable polymer coating (36) allows for data logging, tracking, and data storage devices to be embedded within panel assemblies (12, 14, 16, 18) for effective management of panel assemblies (12, 14, 16, 18) for reuse and support ofin use shipments. For example, durable polymer coating (36, 36a) may encapsulate individual panel assemblies (12, 14, 16, 18) including sensor (20) and / or data logger (62). This allows tracking and identification during assembly, transit, use, and return to global service centers.
[0061] Container (10) provides reusability like a completely rigid shipping system without the increased shipping and repositioning costs or time-consuming repairs where the entire rigid container is out of commission for the duration oof the repair. Should a specific panel assembly (12, 14, 16, 18) sustain damage, repairs may be performed to that specific panel assembly (12, 14, 16, 18), while the remaining panel assemblies (12, 14, 16, 18) are returned to stock and reused. The collapsibility of panel assemblies (12, 14, 16, 18) provides reduced space requirements and ability to stack for efficient return, repositioning and reuse of container (10), while durable polymer coating (36, 36a) ensures this may be achieved with limited damage. Durable polymer coating (36, 36a) allows panel assemblies (12, 14, 16, 18) to provide superior performance during use and of reuse and managementby the customer and / or manufacturer. Container (10) ensures that the lifecycle of materials is maximized prior to being disposed.

[0072] FIG. 15 shows container (10) of FIG. 1 in the non-assembled configuration. In the non-assembled configuration, panel assemblies (12, 14, 16, 18) are stacked for storage or shipment and do not define the volume. The non-assembled, flat pack, configuration, allows container (10) to be returned efficiently for refurbishment / cleansing and reuse efficiently at lower cost. This non-assembled configuration may reduce the volume by about 2 / 3. Applying the durable polymer coating (36) to panel assemblies (12, 14, 16, 18) and not the entire container (10) as a single unitary component allows for additional flexibility. In some versions, two panel assemblies (12, 14, 16, 18) may be coupled and then collectively coated with durable polymer coating (36).
[0073] FIGS. 16 and 17 show select portions of another side panel core (78a) not including durable polymer coating (36). FIG. 16 shows select mating surfaces of side panel core (78a).

At least some of mating surfaces of panel assemblies (12, 14, 16, 18) do not include durable polymer coating (36) to minimize thermal bridging. As shown, mating surfaces include a mitred edge. A portion of each panel assembly (12, 14, 16, 18) includes durable polymer coating. Selective application of durable polymer coating (36) may keep thermal bridges between adjacent panel assembly (12, 14, 16, 18) to a minimum. A thermal bridge may be considered a “path” of energy transport. By making this “path” longer and creating a tortuous path, energy loss is increased on the path which improves the insulative R-value.
[0075] FIG 18A shows side panel core (78) coupled with corner protector (28a) prior to the application of durable polymer coating (36). As a result, durable polymer coating (36) covers both side panel core (78) and corner protector (28a) to bond side panel core (78) and comer protector (28a) together.
[0076] FIG. 18B shows an example of another edge protector (30a) that may be used instead of edge protector (30).

In one version, durable polymer coating includes a first amine input component and a second isocyanateinput component. In other versions, the durable polymer coating includes a first polyol input component and a second isocyanate input component. In some versions, durable polymer coating (36) may be applied as a uniform thickness of about 0.5 millimeter or above covering each surface of panel cores (40, 78, 106, 120) to encapsulate each individual panel core (40, 78, 106, 120). Durable polymer coating (36) applied via spraying or painting on and may be used to combine and robustly join different insulative materials to provide a durable composite panel assembly (12, 14, 16, 18). Prior to step (212), it may be beneficial to reduce the moisture content of panel assemblies (12, 14, 16, 18), including panel assembly (12, 14, 16, 18).
[0081] At step (214), method (210) includes applying a second layer (144) of polyurea, polycarbonate, polyurethane, polyether, polyester, epoxy resin, nylon, or acrylic coating to at least outer surface of panel cores (40, 78, 106, 120). First layer (142) of polyurea, polycarbonate, polyurethane, polyether, polyester, epoxy resin, nylon, or acrylic coating and second layer of polyurea, polycarbonate, polyurethane, polyether, polyester, epoxy resin, nylon, or acrylic coating have different thermal emissivities. The polyurea, polycarbonate, polyurethane, polyether, polyester, epoxy resin, nylon, or acrylic coating may have a color configured to minimize thermal emissivity, to only outer surfaces (50, 88, 110, 126) of first panel assembly. In some versions, a durable sheet material (not shown) may be applied to panel assembly (12, 14, 16, 18) instead or in additional to the spray applied, brush applied, or roller applied coating. For example, a polystyrene sheet may be heat applied (e.g., in mold or post mold) to panel cores (40, 78, 106, 120). Second layer (144) may have a different color such as a white low thermal emissivity (“low e”). For example, second layer (144) may include titanium oxide or another whitening agent to reduce thermal emissivity.
[0082] As step (216), method (210) optionally includes inserting data logger (62) at least partially within a recessed portion of outer surface of first panel core after applying first layer of polyurea, polycarbonate, polyurethane, polyether, polyester, epoxy resin, nylon, or acrylic coating.
[0083] J. Second Exemplary Method of Manufacture
