Abstract

An article suitable for outdoor construction applications is provided. The article includes an inner layer having a CPVC composition and an outer layer having a CPVC composition. An intermediate layer is sandwiched between the inner and outer layers. The intermediate layer is a PVC composition.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . An article for construction applications comprising:
 a. an inner layer comprising a CPVC composition;   b. an outer layer comprising a CPVC composition; and   c. an intermediate layer sandwich between said inner and outer layers, the intermediate layer comprising a PVC composition.   
     
     
         2 . The article of  claim 1  further including a cap layer adhered to the CPVC composition outer layer. 
     
     
         3 . The article of  claim 1  wherein the CPVC composition is at least 16 weight percent of the material of the article. 
     
     
         4 . The article of  claim 1  wherein said article includes a siding panel. 
     
     
         5 . The article of  claim 1  wherein the CPVC composition has a heat distortion temperature greater than 180° F. 
     
     
         6 . The article of  claim 1  and further including a layer of insulation foam adhered to the inner layer. 
     
     
         7 . The article of  claim 1  wherein at least one of the inner layer and the outer layer has a thickness in the range of 2 to 19 mils. 
     
     
         8 . The article of  claim 7  wherein at least one of the inner layer and the outer layer has a thickness in the range of 4 to 6 mils. 
     
     
         9 . The article of  claim 1  wherein the outer layer is a dark color having an L value less than 50. 
     
     
         10 . The article of  claim 1  wherein the intermediate layer comprises more than an insignificant amount of talc. 
     
     
         11 . The article of  claim 1  wherein the article having a CPVC material content of 16 weight percent is deflected less than 5 mm in Oven Sag Tests performed at 180° F., 200° F., and 230° F. 
     
     
         12 . The article of  claim 1  wherein the article has a thickness of from about 30 to about 50 mils. 
     
     
         13 . The article of  claim 12  wherein the article has a thickness of from about 40 to about 48 mils. 
     
     
         14 . The article of  claim 2  where said cap layer is selected from the group consisting of PVC, ASA, and fluoropolymer. 
     
     
         15 . The article of  claim 14  wherein said cap layer comprises a fluoropolymer and has a thickness of from about 1 to about 2 mils. 
     
     
         16 . The article of  claim 1  wherein at least one of the inner layer and the outer layer has a thickness in the range of from about 3 to about 10 mils. 
     
     
         17 . An article for construction applications comprising:
 a. an inner layer comprising a high heat plastic composition;   b. an outer layer comprising a high heat plastic composition; and   c. an intermediate layer sandwich between said inner and outer layers, the intermediate layer comprising a PVC composition.   
     
     
         18 . The article of  claim 17  in which at least one of the high heat plastic compositions of a. or b. is a CPVC composition.
