Exterior Moulding Systems
Our maintenance free exterior mouldings are engineered to withstand outdoor conditions while providing superior aesthetic appeal and protection for building facades — outperforming traditional exterior moulding materials such as pre-cast concrete, wood, MDF, and PVC. From window and door trim to window sills and crown and cornice mouldings, every profile is engineered for the same maintenance-free performance.

Superior Architectural Details
Our foamcore architectural mouldings, including both exterior cement-coated moldings and interior plaster-coated profiles, provide versatile, moisture-resistant, and lightweight alternatives to traditional materials, suitable for both interior and exterior applications.
Consistent Performance at Every Opening
Designed for easy installation and long-lasting performance, our mouldings work well in residential, commercial, retail, and hospitality projects — especially when paired with maintenance-free exterior window trim and casing to ensure consistent performance around key openings.
Crown Mouldings & Window Sills
Whether you are specifying crown moulding, decorative trims, or architectural exterior window sills like The Deevale, our high-performance materials offer the perfect balance of style and function, backed by expert advice and customizable options.
Interior Plaster Mouldings
Our lightweight, plaster-coated interior crown mouldings bring elegance and architectural relief to walls and ceilings without the weight or fragility of traditional hand-run plaster — a durable alternative that installs cleanly and holds its finish over time.
Interior Moulding Systems
Decorative interior mouldings are primarily made from plaster-coated EPS, offering modern options suited to both traditional and contemporary spaces and supporting a wide range of design aesthetics. Explore our lightweight interior crown mouldings, including The Alston, and our one-piece coffered ceiling beams for dimensional detail overhead without the weight of solid millwork. Selecting mouldings means matching the architecture and scale of the room — combining profiles thoughtfully can help a space feel taller, larger, or more finished throughout.
INTERIOR PERFORMANCE COMPARISON
| Attribute | Mouldex Interior Mouldings | Traditional Plaster | MDF (Metrie / Alexandria) | Synthetics (Ekena / Orac Decor) |
|---|---|---|---|---|
| Finish Quality | Genuine Smooth Plaster | Hand-Run Smooth Plaster | Painted Fiber (Grainy Texture) | Molded "Plastic" Look |
| Stability | Crack-Resistant Composite | Prone to Hairline Cracks | High Joint Expansion | Brittle over time |
| Fire Safety | Non-Combustible Surface | Non-Combustible | Combustible Wood Fiber | Flammable Polymers |
Complement Decorative Trim With Wall Claddings
Enhance both interior and exterior surfaces with our range of no maintenance stone, brick & wood wall claddings — providing texture, depth, and durability while maintaining a lightweight, maintenance-free profile. Composite wood grain panels bring warmth without the rot or upkeep of real siding, while cement-coated stone and brick veneers pair perfectly with exterior window trim for a cohesive, layered facade. Exterior middle band mouldings tie it all together, introducing strong horizontal lines between floors to unify claddings and trim into one composition.

Why Choose Mouldex Mouldings?
Engineered for Performance
Moisture-resistant, engineered materials for long-lasting life, low maintenance, and added protection at points of frequent touch or exposure. Lightweight and easy to install, reducing labor costs, and well suited to painted finishes and durable use without introducing moisture-sensitive materials in wet areas.
Versatile Moulding Design Options
Wide variety of moulding collections and styles, from window sills to larger trims and exterior composite column wraps, plus bespoke custom options well suited for high-end builds or restoration projects requiring precision replication.
Rooflines & Crowns
Exterior crown moulding creates a strong visual transition at the roofline. Profiles such as The Goulding and The Portland introduce dramatic, traditional shadow lines, while grand profiles like The Norton suit estate-scale exteriors requiring a bold roofline transition.
Window & Door Framing
Frame architectural features with added sophistication using profiles such as The Jackson exterior window trim or The Kamloops exterior door trim. Half round moulding offers a simple option for smooth transitions between spaces.
Interior Crown Mouldings
Add elegance and architectural relief to flat wall and ceiling surfaces with our lightweight interior crown mouldings, including profiles like The Alston, pairing naturally with select exterior column wraps for a unified design.
