Abstract
A construction component comprising a foamed cellular board comprising smooth exterior surfaces separated by a cellular network and cut edges, and sealed caps adhered to the cut edges on the foamed cellular boar. The board has a density of less than 0.55 g/cm3, and the cut edges on which the sealed caps are adhered are unmelted edges.

A construction component comprising:
- a foamed cellular board comprising smooth exterior top and bottom surfaces separated by a cellular network and cut edges;
- and
- sealed caps adhered to the cut edges on the foamed cellular board derived from PVC molecules solvated in a plasticizer;
- wherein the board has a density of less than 0.55 g/cm3;
- wherein the cut edges on which the sealed caps are adhered are unmelted edges;
- wherein the foamed cellular board and the sealed caps are different compositions;
- wherein the smooth exterior top and bottom surfaces are hard skins formed during extrusion and cooling of the foamed cellular board.
