[0001] This is a divisional application of application Ser. No. 10/609,030 filed on Jun. 26, 2003, which is a divisional application of application Ser. No. 09/928,153 filed on Aug. 10, 2001, now U.S. Pat. No. 6,719,277. BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The present invention relates generally to thermoplastic fencing, wall and building structures. [0004] 2. Description of Prior Art and Related Information [0005] Until recently, fences have typically been composed of wood or metal. Wooden fences include several drawbacks. Such fences are susceptible to a great deal of wear and tear caused by natural elements, such as heat, wind and rain. The cost of the wood itself can be quite high, especially if a fence needs to be replaced. Corrugated metallic fences include several drawbacks as well. Not only is the metal subject to corrosion, but metallic fence sheets lack rigidity and dent easily. In addition to the susceptibility to deterioration, metallic fences tend to present a flimsy and cheap appearance. [0006] As an alternative to wood fences, thermoplastic fencing assemblies have been provided with components formed to resemble wood fencing structures. Such thermoplastic assemblies include extruded, hollow tubes shaped to resemble planks. The "planks" are joined by horizontal "rails" and coupled to posts, all of which also consist of plastic, extruded tubes. Though such thermoplastic assemblies do not deteriorate in the same manner as does wood, the plastic fences of the prior art have their own disadvantages. [0007] With respect to cost, the prior art assemblies include "planks" that are individually extruded. In particular, each plank consists of a separately extruded tube. As extruded tubes with hollow cores and open ends, caps are required to cover at least the tops of each tube in order to preserve aesthetics. Having to extrude each plank separately, however, leads to high costs. Each plank must then be secured to one or more horizontal rails, which increases costs and complexities related to assembly. [0008] A further disadvantage of existing plastic fences includes the inability to withstand heat. Fences are generally provided for the outdoors where they are subject to the sun. In prior art plastic fences, each individual plank is extruded as a hollow tube, with a thin layer of plastic material. If the tubes are dark colored, a greater amount of heat from the sun is absorbed and captured within their hollow cores. The heat absorption exacerbated by dark colored tubes causes the thin tubes to deform. SUMMARY OF THE INVENTION [0009] The present invention provides structures and methods which overcome the deficiencies in the prior art. [0010] In one aspect, a fence assembly is provided. The fence assembly comprises a thermoformed panel, a reinforcement coupled to the panel, and a post coupled to the panel. The thermoformed panel comprises a top, a bottom, a first axis defined between the top and the bottom, a plurality of stakes, with each stake extending parallel to the first axis and having a top return extending perpendicular to the first axis, and a nestable side portion. Each rearwardly projecting top return comprises a rounded curved shape. Each stake comprises a major portion and a minor portion that meet at a forwardly protruding ridge. [0011] The assembly further comprises a side cover coupled to a side portion of the panel and a bottom flange. The reinforcement comprises a hollow bar and a solid insert disposed within the bar. The assembly further comprises a flat vertical portion disposed between each stake, wherein the reinforcement is welded to the flat vertical portions. [0012] In another aspect, a fence assembly comprises a first post, a second post, a first thermoformed panel having a first plurality of vertically extending stakes with top returns, and a first side portion, and a second thermoformed panel having a second plurality of vertically extending stakes with top returns, and a second side portion configured to overlap the first side portion of the first thermoformed panel. The first thermoformed panel is disposed side-by-side with the second thermoformed panel such that the second side portion overlaps the first side portion. The first thermoformed panel and the second thermoformed panel are disposed in between the posts. The first thermoformed panel is coupled to the first post, and the second thermoformed panel is coupled to the second post. The assembly further comprises horizontal reinforcements coupled to the panels. The first side portion comprises a first laterally extending flange. The second side portion comprises a forwardly extending flange connected to a second laterally extending flange. [0013] A double-sided wall structure is also provided. The structure comprises a frame having a first side and an opposite second side, a first thermoformed panel coupled to the first side of the frame, and a second thermoformed panel coupled to the second side of the frame. The first thermoformed panel comprises a first three-dimensional, non-extrudable front surface and a first rear surface substantially parallel to the first front surface. The second thermoformed panel comprises a second three-dimensional, non-extrudable front surface and a second rear surface substantially parallel to the second front surface. The frame comprises at least a top horizontal beam, a bottom horizontal beam, a first vertical beam and a second vertical beam. [0014] The structure further comprises a support bar coupled to the top horizontal beam of the frame and a support bar coupled to the bottom horizontal beam of the frame. Side covers are coupled to at least a portion of the structure perimeter, namely to first and second sides of the structure. A post is coupled to the frame. The first rear surface comprises a first plurality of flat sections. The second rear surface comprises a second plurality of flat sections. The frame is coupled to the first and second plurality of flat sections. [0015] In a further aspect, a double-sided wall assembly comprises a first sub-assembly, a second sub-assembly, a first post, and a second post. The first sub-assembly comprises a first frame, and a first pair of thermoformed panels coupled to opposite sides of the first frame. Each of the first pair of thermoformed panels has a front surface and a rear surface. The panels of the first pair are coupled to the first frame in a back-to-back configuration. The second sub-assembly comprises a second frame, and a second pair of thermoformed panels coupled to opposite sides of the second frame. Each of the second pair of thermoformed panels has a front surface and a rear surface. The panels of the second pair are coupled to the second frame in a back-to-back configuration. The first sub-assembly and the second sub-assembly are disposed side-by-side and in between the posts. [0016] The assembly further comprises a first pair of brackets coupling the first sub-assembly to the first post, and a second pair of brackets coupling the second sub-assembly to the second post. The assembly further comprises a first, upper support bar and a second, lower support bar juxtaposed in an overlapping relationship with the first frame and second frame. A top cover and a bottom cover are disposed over the first sub-assembly and the second sub-assembly. [0017] A method for manufacturing a fencing assembly is provided.
