Alcoa, CertainTeed, Wolverine, and other major manufacturers
of vinyl siding produce vinyl details that give pedestrian siding systems
a classic look. Some of their offerings include window and door surrounds,
shutters, corner posts, dentil molding and a range of other components,
as well as decorative custom shingle and siding patterns.
For example, Alcoa Building Products' line of Images Designer Accessories
includes Accent Panels in four fish scale patterns, wainscot, dryer vents
and fixture mounts. These decorative accessories are available in a wide
range of colors and can be used with vinyl and aluminum siding, brick and
stone.
CertainTeed has gone to great lengths to create trim that mimics the look of wood. Wolverine also offers a realistic line that includes a premium, super-rigid soffit; fish scale, beaded and lattice panels; extra-wide fluted, stepped, or smooth corner posts; and stepped window trim.
If your home is sided with aluminum, you may be able to use some vinyl specialty parts; otherwise, you can get custom-bent aluminum pieces for some architectural features, but these tend to be expensive and not very authentic looking.
