CertainTeed’s Vertical Siding is a more classic take on siding style and has different design options like board & batten, insulated board & batten, and chamfer board. The board & batten design has alternating wide and narrow cedar boards, and the insulated board & batten has a foam insulation technology to save energy, absorb sound, and resist impact. Chamfer board siding is made to look like beveled-edge wood but with the durability of vinyl. The board & batten was a design that early settlers used to protect and style outbuildings and homes and the insulated version is a combination of this historic siding with a new, innovative technology. CertainTeed chamfer board siding has a unique v-groove lock design to it, is extra thick, and has a brush finish to it. All CertainTeed vertical siding has a class 1(A) fire rating, a lifetime limited warranty, and never needs painting. CertainTeed siding is basically maintenance free.
