Enerfrees is a proudly Canadian-owned manufacturer of engineered, high-performance aluminum curtain wall, window wall, and entrance door systems designed for commercial, institutional, industrial, healthcare, and residential applications.
Our systems are engineered to meet stringent structural, thermal, air infiltration, and water penetration performance requirements in accordance with applicable CSA and North American standards. We integrate advanced thermal break technology, precision fabrication, and quality-controlled manufacturing processes to ensure long-term durability, energy efficiency, and code compliance.
At Enerfrees, we combine technical expertise with responsive project support — from design development and shop drawings to fabrication and field coordination — delivering cost-effective solutions without compromising performance or aesthetics.
Our mission is to provide safe, thermally efficient, durable, and environmentally responsible building envelope systems that contribute to sustainable building performance.
Key Features of Our Engineered Systems
Integrated System Design
Each product is developed as a fully integrated system — incorporating extrusions, hardware, accessories, glazing, sealants, gaskets, and anchoring components. Our systematic design approach ensures that all elements function cohesively to deliver optimal structural, thermal, and weather performance.
Engineering Oversight
From concept development through fabrication, every product series is supervised by experienced engineers to ensure compliance with original design intent, performance criteria, and applicable standards.
Custom Tooling & Controlled Manufacturing
All components are produced using precision-engineered custom dies and modern manufacturing equipment, following standardized and quality-controlled processes. This ensures dimensional accuracy, repeatability, and consistent product performance.
Tested and Field-Proven Performance
Individual components and complete assemblies undergo rigorous laboratory testing and practical field validation to meet high structural, air infiltration, water penetration, and thermal performance requirements.
Process Control & Dimensional Accuracy
Our controlled system approach minimizes manufacturing variability. Custom-designed components are engineered to accommodate tolerances and reduce cumulative dimensional deviations, resulting in reliable installation and long-term performance.
Comprehensive Performance Integration
Each system is engineered to balance structural strength, air tightness, water resistance, thermal insulation, acoustic performance, solar heat gain control, and weather durability — delivering safe, comfortable, and energy-efficient building environments.
