Marvin. Extreme temperatures, high humidity, salt water, and major storms are welcome challenges for Apex Ultrex Siding. Users may recognize the Ultrex name from the maker’s Integrity and Infinity lines of windows and doors. The same pultruded fiberglass material makes Apex siding a low-maintenance, moisture- and impact-resistant alternative to fiber-cement, wood, and vinyl siding. A self-aligning interlocking design means tight seams and no visible nail holes. Available in 10 colors, smooth or wood-grain finishes, and 4- or 7-inch widths. 888.215.1092.
