Cedar does rot, but it resists rot better than most types of wood. Cedar is a porous, light wood type that gives it an insulating value ideal for use as home siding products.
When used as a fence post, cedar wood rots when it has been encased in cement in a post hole. Cedar also stands up well to moisture and resists damage caused by different insects better than other wood types. In addition, this porous wood absorbs noise and is known for its long-lasting qualities. Cedar wood used for home siding is a high-demand product as it gives a prestigious and elegant finish to homes.
