Our this pvc foam board is PVC that has been extruded and whipped into a less dense aerated foam that results in a material with the working characteristics and density of white pine. It's lighter and less expensive than solid PVC. Because of these characteristics, cellular PVC can be cut, milled, shaped and routed just like wood with normal woodworking tools. The process used to make cellular PVC allows for milled edges that are smooth. Most cellular PVC is produced in a natural white color throughout, and while it never needs painting, it's easy to custom finish. Cellular PVC is the perfect wood alternative - you'll find that now, and in the future, there will be many uses of PVC. For more PVC foam boards, please contact us.
