Familiar geometry makes round-edge shingles our most popular, versatile shape. Choose rounds to add distinctive dimension to gables or anywhere that texture can add interest to the home, and combine colors for a one-of-a-kind effect. Using molds made from genuine cedar, Foundry vinyl round siding features a subtle grain and saw marks to lend a truly authentic air. Year after year, Foundry vinyl shingle siding holds its rich color, thanks to a durable ASA cap that protects against UV rays and the elements. What's more, Foundry siding is backed by a limited lifetime warranty and provides the highest level of fire resistance and toughness to stand up to any environment.
