Beyond Traditional Plaster & Wood/MDF: 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 |
Mastering Hybrid Plaster Installation
Achieve a seamless, professional finish without the mess of traditional solid gypsum. Our Hybrid Plaster profiles are engineered for clean, rapid installation using high-strength adhesives. Watch our technical guide to see how precision miters and single-piece spans simplify high-end architectural trim.
Yes. Unlike wood or MDF, which require "building up" multiple pieces to create a large 10-inch or 12-inch profile, Mouldex manufactures large-scale cornices and beams in single, seamless spans. This eliminates the joint-failure risks and visible seams common in multi-member wood assemblies, providing a perfect monolithic silhouette.
Absolutely. Our plaster coating is specifically engineered for High Opacity to prevent "light bleed." This makes our Interior line the industry standard for indirect cove lighting and glowing coffered ceiling designs, as the light won't shine through the material.
Our interior mouldings are dimensionally stable, meaning it does not shrink, warp, or expand like wood or MDF. This ensures that your miter joints and corners stay permanently closed, regardless of the humidity levels in your home or building settlement.
Precision Coffered Ceiling Engineering
Traditional coffered ceilings require heavy wood framing and structural blocking. Mouldex one-piece beam profiles eliminate the weight and the complex assembly. Watch how our dimensionally stable beams create massive architectural impact with a simple, high-bond adhesive application.
The 5th Category: Interior Coated Expanded Polystyrene
Interior details typically fall into four categories: MDF (Metrie/Alexandria), Traditional Solid Plaster, Wood, or Synthetics (Ekena/Orac Decor). Mouldex introduces an additiona to the superior 5th category: Plaster Coated Expanded Polystyrene for interiors.
Engineered to provide the prestigious, ultra-smooth finish of hand-run plaster without the extreme weight or fragility, our Hybrid Plaster systems utilize a high-density core protected by a genuine and proprietary plaster coating.
This results in an architectural profile that delivers the authentic aesthetic of traditional plaster while remaining crack-resistant and 90% lighter than masonry alternatives.
By eliminating joint expansion common in MDF and the "plastic" appearance of Polyurethane, Mouldex ensures a monolithic, seamless finish for high-end residential and commercial interiors.
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.
