There have been many discussions over the years about these two products. composite is good but like any man made product on the market today will expand and contract with temperature changes. Pressure treated over time can slightly shrink as well. these pictures show a deck we just recently finished and as you can see this material is awesome. very few knots and looks amazing. if you can find a contractor that will take the time to carefully select the materials you dont need to spend thousands of dollars on a composite deck. Just "food for thought" enjoy, summer isnt to far away?????
