Reproduced from classic weatherboard designs, beaded weatherboard features a wide clapboard face highlighted by a distinctive bead at the base of the panel. Made of PVC, the siding features a historically correct 7/16-inch profile in a 6 1/2-inch exposure. Backed by a lifetime warranty, the low-maintenance siding looks like natural cedar but resists insects and moisture and won't rot or warp, the maker says. 866-393-8883.
