An architrave is the trim that surrounds a door or window opening, including the head casing, the side casings, and the more elaborate moldings that may be applied above or around the opening. In luxury homes, the architrave is a substantial architectural element, not just a simple casing.
The most common luxury architrave is a multi-piece assembly. A wider base casing, a smaller secondary casing applied on top of the base, a small fillet or cove, and a top casing. The assembly has 3 to 5 layers of trim, each with its own profile, creating a substantial architectural surround.
A second common luxury architrave is a single developed profile. A wider casing (150 to 250 millimeters) with a developed classical profile (a cyma, a torus, a small decorative band). The single piece has the same visual weight as a multi-piece assembly, but the install is simpler.
A third common luxury architrave is a paneled surround. A surround with raised or recessed panels in the head casing and the side casings. The panels add detail to the surround, and the door or window reads as a substantial architectural element.
A fourth common luxury architrave is a surround with a breakfront. A head casing with a central projecting element (the breakfront) and two side returns. The breakfront adds depth to the surround, and the door or window reads as more substantial.
A fifth common luxury architrave is a surround with integrated lighting. A head casing with a small channel that hides an LED strip, washing the wall or the ceiling with indirect light. The lighting adds an architectural effect, and the door or window reads as a designed element.
For sourcing, luxury architraves are usually custom or semi-custom. The factory's catalog may include some standard developed profiles, but the specific application often requires a custom design. The lead time is longer than for stock casings, and the minimum order is higher.
A practical install note: a luxury architrave requires more careful planning than a standard casing. The wall should be checked for flatness, the door or window frame should be checked for square, and the architrave should be dry-fit before any adhesive goes on. The install sequence is: base casing first, secondary casings second, top casings and decorative elements last.
A practical note on the design coordination. The luxury architrave should be coordinated with the room's other architectural elements — the baseboard, the chair rail, the crown, the panel moldings. The architrave's design should share a proportional language with the other trim, and the finish should match. An architrave that doesn't coordinate with the rest of the room's trim reads as an addition, not a design element.

Frequently Asked Questions
Q: What is polyurethane (PU) decorative material?
A: Polyurethane (PU) decorative material is a high-density closed-cell polymer molded into architectural profiles such as cornices, ceiling medallions, wall panels, columns, and skirting boards. It replicates the appearance of plaster, carved wood, or stone at one-quarter the weight, is fully waterproof, impact-resistant, and arrives factory-primed for paint.
Q: How does PU compare with plaster and wood mouldings?
A: PU is lighter than plaster (no scaffolding required), impact-resistant during transport, and immune to cracking. Compared with wood, PU does not warp, split, or attract termites, and it tolerates moisture in bathrooms and kitchens. The trade-off: PU cannot be refinished the way solid wood can, but its lifespan is 20–30+ years with minimal maintenance.
Q: How do you cut and finish PU mouldings?
A: Cut PU mouldings with a fine-tooth miter saw (40+ teeth for a 10-inch blade) to avoid chipping the molded edge. Sand the cut edge with 220-grit, then apply two coats of interior latex paint. Mitre joints at corners, fill seams with lightweight spackle, sand smooth, and finish with one final top coat.
Q: Is PU moulding safe for indoor air quality?
A: Yes. Premium PU mouldings are manufactured without formaldehyde, asbestos, or VOCs. They meet EN 13501-1 Class E fire classification as a minimum, with Class B fire-retardant versions available for commercial projects. The factory-applied water-based primer further reduces off-gassing once installed.
