The Bianca Interior Plaster Crown Moulding

The Science Behind the Most Versatile Moulding on the Planet

Mouldex interior mouldings represent a definitive shift in high-end trim, combining the authentic aesthetic of traditional plaster with advanced material performance.

Engineered for both historical restorations and contemporary luxury design, our Evolved Foamcore technology addresses the structural and labor-related failures inherent in wood, PVC, and solid gypsum casting. By replacing brittle, heavy materials with a resilient, lightweight core, we provide a rock-hard finish that remains permanently stable regardless of seasonal humidity or building settlement.

1. The Evolved Plaster Core

Mouldex interior profiles utilize a high-density Evolved Foamcore encapsulated in a proprietary polymer-modified architectural plaster. Unlike brittle solid gypsum which is prone to shattering, this system is physically resilient, providing a rock-hard, smooth surface with internal flexibility that prevents surface cracking.

2. Monolithic Seamless Spans

We eliminate the failure points of built-up wood assemblies. While traditional wood requires 3 to 5 separate members to achieve a 12-inch profile, Mouldex manufactures massive cornices in a single, seamless span.

• Zero Visible Seams: Eliminates the joint separation common in wood due to seasonal humidity.
• Labor Efficiency: Reduces on-site installation time and specialized carpentry costs by up to 70 percent.

3. Structural Weight Efficiency

Our interior systems are 90 percent lighter than traditional solid plaster or heavy wood assemblies. This allows for massive architectural impact on standard framing without the need for expensive structural blocking or reinforced headers.

4. Dimensional Stability and Material Memory

Traditional plaster is rigid and shatters during building settlement, while wood warps and shrinks. Mouldex possesses Material Memory, allowing the profile to absorb minor building shifts without developing hairline fractures. Your miters stay closed permanently, regardless of seasonal shifts.

5. High-Opacity LED Integration

Standard polyurethane and plastic mouldings suffer from "light bleed" when paired with modern LEDs. Our architectural coating is engineered for High Opacity, creating a total light block. This makes our Light Cove and Ceiling Beam series the professional choice for integrated indirect lighting systems.

6. Bespoke Heritage Replication

Using advanced CNC technology, we replicate historical heritage profiles or create bespoke contemporary shapes with an average 7 to 10 day turnaround. This eliminates the 8 to 12 week lead times and extreme waste associated with traditional plaster casting.
