Composite trims, which may be either wood/plastic, cellular PVC, polyurethane, or vinyl, come in several different material formulations, weights, dimensions, and textures, but they all claim better performance than wood exterior trim, manufacturers say. Here are some of the newest composite trim products.
Measuring 16 inches wide, MiraTec Treated Exterior Composite Trim is now available in a 5/4-inch thickness. The trimboards are made of wood bonded with resins and treated with zinc borate wood preservative, ensuring rot and moisture resistance. MiraTec trimboards are factory primed on all four sides and feature a cedar-like texture on one face and a smooth finish on the other. 800.255.0785. www.miratectrim.com.
Manufactured from cellular PVC, Trimplank trimboards from Royal Mouldings can be used for both exterior and interior trim applications.

Available in 18-foot lengths and factory primed, the trim-boards come in smooth, wood-grain, or stucco textures. 800.368.3117.www.royalmouldings.com.
MoistureShield composite trims from AERT are manufactured from a blend of 50 percent recycled polyethylene plastics and 50 percent recycled wood fiber.

New from Azek, Frontier Cornerboards, made of cellular PVC, feature a rustic wood texture and come ready to install, the maker says.

Cellular PVC foam boards and sheets from Fypon have a density comparable to white pine, the maker says, but will not decay, cup, swell, split, or delaminate. The products' white color is molded throughout, allowing the boards and sheets to be fabricated in the field. The boards and sheets come with a smooth surface on both sides, or reversible with one smooth side and one wood-grain textured side. 800. 446.3040.www.fypon.com.
Royal Wood Crown Molding and Door Jambs are made from a solid core of wood flour and resins co-extruded with a non-PVC polymer cap for a fade-resistant color finish.
