AZEK Beadboards have the same high-quality and lasting performance of other AZEK Trim and Moulding. Unlike wood, AZEK Beadboards resist moisture and insect damage and will not cup, rot, or split. Leave the constant maintenance of wood behind with beadboards that retain a like-new appearance despite the tests of time and weather. AZEK Beadboard is reversible with an edge and center bead on one side and a v-groove on the other, perfect for wainscoting and porch ceilings.
