Crownduit’s Removable Miterless Moulding System

Crownduit® is an environmentally friendly crown moulding system. The system combines a PVC backed paintable  MDF faceplate with a PVC mounting track, offering serviceability for telecommunication installations. Crownduit® is a complete component system — no mitering, nails or putty required. Overlapping seam covers eliminate seams from opening due to expansion and contraction. Crownduit® beautifies any room as a crown moulding by itself, with the added advantage of a built-in wire chase for future wire management needs. US Patent 8,779,290 B1


MDF Faceplate

Crownduit’s faceplate and components are made from Trupan Premier MDF, is fully paintable and is environmentally friendly.

When requested we add a Greenlights Coatings Self Crosslinking Clear Acrylic Sanding Sealer fire retardant additive to our primer, and custom paint colors.

PVC Wire Chase

Crownduit’s internal wire chase is made of Color Master CMR4240 NAT 01 ridged PVC compound. 57% of PVC is made out of chlorine, which is delivered from common salt that is abundant on earth. Therefore PVC contributes significantly to saving oil or gas, which are non renewable resources, in comparison to other plastics whose composition depends entirely on oil. Crownduit’s internal wire chase is self extinguishable, made from 100% pure virgin PVC.


This style of moulding has an inward sweep of crown called scotia or cyma recta, the Greek word for wave or upright (cove). The convex curve is called ovolo (ogee). It is derived from classic Greek architecture.

The style dominates American trim work from the Greek revival period (circa 1820s) onward. The cove and undulating ogee form a classic pair. The shape brings together two basic building blocks of profiles and would appropriately embellish the interior in most style houses/buildings.

Our moulding styles come with seam covers and inside and outside corners that are self aligning. The Traditional line comes in two sizes, the 45 crown is 5 1/4″ profile, and the 48 crown is a 4 1/4″ profile.
