Engineered to outperform rot-prone wood and heavy pre-cast stone, these high-performance profiles provide a seamless, monolithic finish for any exterior.
Achieve a permanent, maintenance-free masonry aesthetic with the enduring durability of advanced modern engineering for your facade.
Mouldex window surrounds are engineered to solve the moisture and expansion issues common in traditional wood and PVC trims. Compare our technical performance vs. market alternatives here.
Exterior Window & Door Trim Specifications
Composite Durability
Engineered with a high-density EPS core and polymer-modified cement coating for 100% moisture and rot resistance.
Ultra-lightweight
Weighing 90% less than traditional pre-cast concrete, our trims eliminate the need for structural wall reinforcement.
Zero Maintenance
An insect-proof and weather-resistant alternative to wood and PVC that requires no regular painting or sealing.
Zero-Joint Expansion
Advanced cementitious finish prevents splitting and warping, ensuring seamless joints across all exterior facades.
Mouldex Exterior Composite Engineering & Performance
Exterior architectural mouldings, whether used for window trim, sills, or cornices, play a dual role in both aesthetic enhancement and building protection. At Mouldex, we manufacture a proprietary composite solution designed to solve the inherent failures of traditional masonry and wood materials.
1. The Evolution of Foamcore
Mouldex profiles represent a generational leap in material science. We utilize a High-Density Expanded Polystyrene (EPS) core, wrapped in an alkali-resistant fiberglass mesh and encapsulated in a proprietary polymer-modified cement shield. This creates an inorganic, durbale exterior that is 100% moisture-proof and impact-resistant, engineered to outperform traditional foamcore, pre-cast, wood/MDF, and PVC.
2. Versatile Substrate Compatibility
Unlike traditional trims designed for a single wall type, Mouldex is engineered for Universal Compatibility. Our adhesive-based bonding technology is optimized for a permanent, structural hold on Brick, Stone, Stucco, Vinyl/Siding, and ICF. This eliminates the 0.00003 thermal expansion gaps found in PVC and the moisture rot common in Wood and MDF.
3. Unmatched Customization & Arches
Where rigid materials like PVC and wood fail, Mouldex excels. Our Bespoke Customization allows us to manufacture precision-cut Arches, Full Circles, Ovals, and Ellipticals to match any architectural radius. Utilizing advanced CNC technology, we can replicate historical profiles or create modern shapes with a 7–10 days.
4. Timestone Look Without the Weight
Traditional pre-cast concrete requires expensive structural reinforcement and heavy machinery. Mouldex provides an indistinguishable masonry aesthetic at 1/10th the weight. This Weight Efficiency eliminates the need for cranes or wall-load upgrades, typically providing a 75% total cost savings over stonecast products.
5. Engineered for Freeze-Thaw Cycles
Our proprietary coating is the definitive choice for the Northern US and Canadian climates. While GFRC and fiberglass alternatives often crack under thermal stress, Mouldex is engineered for Zero-Joint Expansion, maintaining its structural integrity through extreme temperature swings.
6. Pro-Grade, Fast-Track Installation
Our Nail-less Installation system utilizes high-bond architectural masonry adhesives. This prevents the building envelope from being compromised by thousands of nail holes and eliminates the risk of rusting fasteners bleeding through your finish over time. For larger shapes, we utilize a rear attachment mechanism for stability and safety.
