Composite Exterior Mouldings & Architectural Trim System
Engineer high-performance building facades with our architectural exterior composite mouldings.
Our proprietary system features a high-density EPS core encapsulated in a rock-hard cementitious coating, providing a zero-maintenance alternative to pre-cast concrete, wood, and PVC.
Lightweight, freeze-thaw stable, and easy to install, Mouldex profiles ensure a permanent, monolithic masonry aesthetic that withstands extreme North American climates for professionals.
Composite Exterior Mouldings & Architectural Trim System Specifications
Engineered with a high-density EPS core and polymer-modified cement coating for 100% moisture and rot resistance.
Weighing 90% less than traditional pre-cast concrete, our trims eliminate the need for structural wall reinforcement.
An insect-proof and weather-resistant alternative to wood and PVC that requires no regular painting or sealing.
Advanced cementitious finish prevents splitting and warping, ensuring seamless joints across all exterior facades.
Compare Mouldex Composite Mouldings vs. Traditional Materials
| Feature | Mouldex | Pre-Cast Concrete | Natural Wood | PVC / Plastic |

| Installation | High-Bond Adhesive | Mechanical Anchors | Manual Carpentry | Mechanical/Fast |
| Freeze-Thaw | Stable / No Cracking | Brittle / Spalling Risk | Rot / Splitting | High Expansion |
| Maintenance | None Required | Regular Sealing | Regular Painting | Fading / Chalking |
As Seen on Discovery Channel: How It's Made
Mouldex was selected by Discovery Channel’s "How It’s Made" to showcase the innovative manufacturing process behind our composite mouldings. By combining advanced CNC-cutting technology with our proprietary cementitious coating, we provide an architectural solution that delivers the authentic look of cast stone with modern material performance.
Yes. Our ultra-lightweight design allows for secure installation over stucco, brick, stone veneer, and traditional siding. Because it requires no structural reinforcement or wall ties, it is the ideal choice for both new builds and renovation retrofits.
Every profile is engineered for Zero-Joint Expansion. Unlike wood or PVC, which warp and split during seasonal shifts, our cement-coated EPS core is dimensionally stable, ensuring your miter joints stay closed through rigorous freeze-thaw cycles.
While Mouldex is 100% moisture and rot-proof, we recommend finishing with any high-quality exterior masonry or acrylic paint. This allows you to match your building’s specific color palette while providing a zero-maintenance, "paint-it-and-forget-it" finish.
Performance-Driven Installation Science
Traditional masonry trim relies on heavy mechanical fasteners that create thermal bridges and structural liabilities. The Mouldex system utilizes high-bond adhesive technology to create a monolithic attachment to the building envelope. This process is 80% faster than pre-cast concrete and ensures a permanent architectural bond that will never separate or fall.
