Crown molding

Historically made of plaster or wood, modern crown moulding installation may be of a single element, or a build-up of multiple components into a more elaborate whole.

Crown treatments made out of wood may be a single piece of trim, or a build-up of multiple components to create a more elaborate look.

The main element, or the only in a plain installation, is a piece of trim that is sculpted on one side and flat on the other, with standard angles forming 90-degrees milled on both its top and bottom edges.

Simplified crown installation is possible when using manufactured corner blocks, requiring only simple butt cuts on each end of lengths of trim.

Plastic and foam versions of crown are now available, typically with corner blocks, for easy installation by DIY home improvement enthusiasts.
