CROSS-REFERENCE TO RELATED APPLICATION 
       [0001]    This application is related to and claims priority to U.S. Provisional Patent Application Ser. No. 61/049,102, filed Apr. 30, 2008, entitled PVC WALL FRAMING SYSTEM, the entirety of which is incorporated herein by reference. 
     
    
     STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT 
       [0002]    n/a 
       FIELD OF THE INVENTION 
       [0003]    The present invention relates to plastic wall framing systems. More particularly, the invention relates to PVC framing systems having snap-on components. 
       BACKGROUND OF THE INVENTION 
       [0004]    Known framing systems include wood framing systems and metal framing systems. These known framing systems are used to construct various residential and commercial building structures, including partitions. 
         [0005]    Wood framing systems are widely accepted by the construction industry. Carpenters are familiar with wood frame construction and can nail wood frames together quickly with nail guns. In spite of the ease of construction, wood framing systems have several drawbacks, including absorbing moisture; increasing fire risk; and increasing susceptibility to insect infestation, rotting, shrinking, warping, and splintering; among other drawbacks. Additionally, the cost of purchasing lumber continues to increase. 
         [0006]    Metal framing systems are less widely adopted than wood framing systems, but have found popularity in the commercial construction industry. The construction industry is trade-oriented, so workers are less inclined to embrace the special training required to properly snip and cut the metal frame members. Additionally, metal screws are needed to construct the metal frames. Metal framing systems have several drawbacks, including poor thermal performance, poor sound performance and tendency to oxidize (e.g. rust), among other drawbacks. 
       SUMMARY OF THE INVENTION 
       [0007]    The invention overcomes these drawbacks and other drawbacks of known systems by providing PVC framing systems having snap-on components. The PVC framing systems may be used to construct various residential and commercial building structures, including partitions. The PVC framing components may include studs and tracks, angles, furring channels, and other PVC framing components. 
         [0008]    According to one embodiment, the snap-on components may employ a tongue and groove configuration. For example, the tracks may include tongues, or protrusions, that engage grooves that are formed in the studs. Alternatively, the studs may include tongues, or protrusions, that engage grooves that are formed in the tracks. As a result, no additional hardware, such as nails, screws, or other hardware may be needed to construct the PVC frames. The snap-on feature reduces the amount of time needed to assemble PVC frames. The snap-on feature also reduces construction costs that otherwise would be associated with fastening the PVC frames, including the cost of the additional hardware (e.g., nails, screws, etc.) and the corresponding power tools (e.g., nail gun, screw gun, etc.). 
         [0009]    According to one embodiment, the PVC framing components may be extruded or injection molded into desired shapes. This allows the PVC framing components to be formed as one piece components with features such as crevices, holes, protrusions and other features. Additionally, the appearance of the PVC framing components may be modified using stains or pigments. 
         [0010]    The PVC framing components provide several benefits over wood and/or metal framing components. For example, the PVC components absorb little moisture; do not oxidize; may be manufactured to reduce fire risk and to eliminate insect infestation, rotting, shrinking, warping, and splintering; among providing other benefits. 
         [0011]    Furthermore, the PVC framing components are workable similar to wood framing components. Thus, end users may continue to use traditional wood working techniques, tools, fasteners, etc., to construct the PVC framing systems. 
         [0012]    These and other features and advantages of the invention will be apparent through the detailed description of the embodiments and drawings attached hereto. It is also to be understood that both the foregoing general description and the following detailed description are exemplary and not restrictive of the scope of the invention.
