There are also other important factors to consider. A solid wood Deck is usually less stable than a composite wood decking. When I say less stable, I am referring to moisture and expansion related to that moisture. When you get climate changes in your home, which you absolutely will, wood decking expands and contracts. With solid wood decking, it generally expands and contracts a lot more than the composite wood. Composite Wood decking is constructed to be dimensionally stable, while most solid wood decks are simply cut pieces of wood from a tree. Considering solid wood decks are cut pieces of wood. There is a lot more room for error or "cabin grade" type wood to be used. What we're saying here is that if you happen to see a solid wood deck real cheap, you are probably getting exactly what you are paying for, junk. While the same holds true for composite wood Decks, there is a lot less cabin grade around.As we mentioned, the solid wood Decks expand more than the WPC decking, and they expand vertically as well as horizontally. While you get little to no vertical expansion with most composite wood Decks, you may get a lot of this vertical expansion of the solid decks. Vertical expansion is when the boards will actually grow up and shrink down in addition to the side to side or horizontal expansion and contraction. The end result of this can be raised beds that sometimes catch your shoes and become a trip hazard. When looking at Wood decking samples, you will notice that most solid, pre-finished wood decks have beveled edges. These beveled edges counteract the raised beds that can become trip hazards, and sort of act as a smoother for the joints. The down side to this is the appearance. Beveled wood decks are not as natural looking. Also, when you get horizontal contraction, when the boards may shrink slightly, unfortunately the bevel edges tend to accentuate these gaps or basically make them look bigger. We have also heard complaints from customers who have had this type of wood decking, that the levels seem to hold the dirt when trying to clean the deck. This could be true depending on the depth of the bevel.
