Abstract

High temperature weather resistant exterior building product articles are disclosed. Articles, such as siding, siding trim, decking, fencing and roofing products are made with a CPVC layer and optionally an insulating layer attached to the CPVC layer. The products have a heat distortion temperature greater than 180° F. and preferably greater than 205° F. The articles can be made in dark colors and have sufficient temperature resistance to withstand direct sunlight in warm climates as well as reflective heat.
