I found some PVC paneling near me, but am unfamiliar with the differences between expanded pvc and "cellular PVC". I'm going to drive over to Home Depot tomorrow to check it out, but I was hoping someone knew of any major differences between the two. Is cellular PVC the same thing as expanded PVC, as they both contain micro air pockets instead of 100% solid PVC?
