Take your deck design from classic to curated

Who says standard-width decking has to be the standard? TimberTech Advanced Polymer has collections offering wide (184 mm) and narrow (89 mm) widths in addition to the standard-width (140 mm) boards—so you can add a touch of the unexpected and an element of style. Whether you like the bold, wide vibe or classic narrow—or want to mix things up by combining more than one—you can create a deck design that is uniquely yours.
