What is composite wood siding and why does it fail?
Often referred to as fake or composite wood, composite wood siding is a man-made product that uses various combinations of wood chips and glue, overlaid with very thin laminate, to give a “real wood” look on the surface. For the most part, composite siding does not handle water very well, causing wood fibers to expand and contract causing the boards to crack, buckle, peel and delaminate. As the paint cracks, it allows more moisture damage to occur, and fungi and bacteria to penetrate the wet wood. Other factors contribute to the failure of composite wood siding such as the quality of its installation and/or the design of the structure.
