Cellular pvc siding, trim, and architectural assemblies

Abstract

Cellular PVC siding, trim, and architectural assemblies are provided which use cellular PVC as an exterior building material due to its stable weatherproof qualities, but which is combined with a substrate to improve the handling and usability of the cellular PVC material. Embodiments of the invention include modular exterior siding assemblies, trim board assemblies, corner trim assemblies, and cylindrical trim assemblies.

         13 . The exterior trim assembly of  claim 10  wherein the cellular PVC trim material is milled to provide the appearance of wooden trim. 
     
     
         14 . An architectural assembly comprising:
 a cylindrical substrate having an outer surface;   two cellular PVC casing components, having channels provided therein to receive the cylindrical substrate, being affixed to and enclosing some or all of the outer surface of the cylindrical substrate.   
     
     
         15 . The architectural assembly of  claim 14  wherein the cylindrical substrate comprises a tubular material. 
     
     
         16 . The architectural assembly of  claim 15  wherein the tubular material comprises a PVC conduit. 
     
     
         17 . The architectural assembly of  claim 14  wherein the architectural assembly comprises a dowel, baluster, column, newel post, handrail, beam, or outdoor furniture. 
     
     
         18 . The architectural assembly of  claim 14  wherein the two cellular PVC casing components are milled. 
     
     
         19 . An exterior corner trim assembly comprising:
 a first rectangular cellular PVC panel having an inner surface and an outer surface, and having first and second long sides, the first long side of the first rectangular cellular PVC panel having a 45 degree edge from the outer surface to the inner surface thereof;   a second rectangular cellular PVC panel having an inner surface and an outer surface, and having third and fourth long sides, the third long side of the second rectangular cellular PVC panel having a 45 degree edge from the outer surface to the inner surface thereof;   said first long side and said third long side being located adjacent each other with the 45 degree edges positioned together to form a 90 degree angle;   a removable adhesive tape retaining the first rectangular cellular PVC panel to the second rectangular cellular PVC panel, said tape being adhered along the outer surfaces of the first long side of the first rectangular cellular PVC panel and the third long side of the second rectangular cellular PVC panel.   
     
     
         20 . The exterior corner trim assembly of  claim 19 , further comprising: a wood material substrate affixed to one or both inner surfaces of the first rectangular cellular PVC panel and the second rectangular cellular PVC panel.
