Azek Building Products. The Azek Mouldings product line now includes 18 profiles with the addition of two new exterior trim products. A 3-inch crown profile offers design versatility, while a 11/2-inch square profile is ideal for inside corners or decorative non-load-bearing pickets. As homeowners and designers demand more ornate low-maintenance trim products, the new profiles offer additional detail in popular sizes. The moldings can also be layered to create classic or historical detail. 877.275.2935.
