Crown molding finishes the line where a wall meets the ceiling or the roof edge. Decorative Architectural Shapes makes crown moldings for interiors and exteriors, from simple cove profiles to ornate, multi-layer designs built around your drawings.

Materials and finishes

Our profiles are CNC-cut from high-density EPS and covered with a polyurea hard coat. The coating makes an exterior crown molding resistant to UV, moisture and temperature swings, while the core keeps each piece light enough for one installer to handle. Unlike a wood or plaster crown molding, foam does not rot, split or crack at joints, and a custom polyurethane molding look can be matched in smooth, stucco or faux-wood finishes.

Choosing a profile

Start with ceiling height and room proportion. A simple crown molding or a thin profile suits modern rooms, while a traditional crown molding with dentils or a deep cove crown molding fits formal spaces. For a decorative ceiling molding or an architectural molding on a façade, we scale the projection and height to the building. We can supply corners, radiused sections and crown molding corner blocks so the run stays clean around bends and returns. If you are comparing a crown molding profiles chart, send us the profile reference and we will reproduce it. Plaster crown molding details, stucco mouldings on a façade and a cove for hidden lighting can all be made from the same foam base, so a single supplier can match interior rooms with the exterior eaves. Long runs ship in sections that are easy to carry, align and join on site.

Foam crown molding is an alternative to polyurethane crown molding, light enough for large rooms and exterior eaves. Custom crown molding, large crown molding and modern crown moldings are cut to your profile, and decorative crown molding corners and crown molding angles are supplied as fitted pieces.

Ordering

Send room or elevation dimensions, linear footage, a profile drawing or photo, and your finish. We prepare a quote, produce the molding and ship it with installation guidance, so your crew knows how to cut, join and finish each run.
