Fiberglass siding from Apex looks like wood but holds up to the elements better than fiber cement, the company says. The siding is made from parent company Marvin’s Ultrex pultruded fiberglass, which, according to the manufacturer, doesn’t require caulking or painting and features an acrylic finish that resists chipping, splintering, fading, and warping more than other siding materials. The siding comes in 10 colors, 4-inch and 7-inch widths, 16-foot lengths, and in a smooth or wood-grain finish. Apex Siding. 888.215.1092. www.apexsiding.com.
