Cellular PVC is completely synthetic and maintenance free wood substitute. It will not absorb moisture, crack, split, warp, delaminate or rot. You have the rich appearance of wood with none of the maintenance issues related to painted wood. It maintains a “like new” appearance in all types of weather. Cellular PVC requires no paint for protection or appearance. It is impervious to wood-boring insects, freeze/thaw cycles and high humidity. Cleaning can be done with soap and water, should it be required. Cellular PVC has insulating value and is very strong for its density. Enjoy years and years of beauty and durability.
