Genovations PVC Decking provides a truly low maintenance deck that will never warp, rot, crack, splinter, or stain. This solid PVC decking with its specially engineered surface also will not absorb moisture because it is a solid structure and there are no wood or foam fillers. Most composites and wood decking materials have to be installed on 16" centers or 12" centers. The Genovations®' decking boards are so strong that you can span them to 24" (16" for 5/4 board) which in turn saves on lumber materials for your deck frame and cuts down on labor. Not only that, this decking's unique tongue & groove installation also helps to create a solid structure so you and your family are guaranteed a safe and strong structure that will last a lifetime!
