About Us
Framing The Future
At Diba Windows, we design and deliver advanced glazing systems that integrate architectural vision with cutting, edge performance. From contemporary homes to large-scale commercial and mixed-use developments, our work is driven by a passion for clarity in light, in design, and in purpose. Every solution is tailored to enhance the built environment while meeting the highest standards of durability, functionality, and beauty.
With over 20 years of experience and more than 3,000 completed projects across the world, our portfolio spans residential, commercial, institutional, and iconic architectural spaces each a testament to our commitment to precision and design innovation.
Our responsibility goes beyond the frame. That’s why our systems are engineered with energy efficiency, thermal performance, and long-term resilience. By minimizing heat loss and noise, and optimizing natural light, our solutions lower environmental impact and create healthier, more enjoyable spaces.
Sustainability is a foundation of our work. From materials to lifecycle performance, we align with evolving energy codes and responsible building practices. We collaborate with architects, developers, and construction professionals who share our values.
At Diba, we don’t just make windows, we frame experiences. With a focus on craftsmanship, innovation, and partnership, we bring visionary spaces to life, one project, one view, and one community at a time.
Our Mission
Uniting design with performance
At Diba Windows, our mission is to support architects, developers, and builders with bespoke glazing solutions that elevate design, optimize performance, and respect the environment. We strive to be more than a supplier, we are technical advisors, creative collaborators, and project partners from concept through completion.
Our systems are built on three pillars:
• Design Excellence
Minimalist profiles, large openings, and architectural precision that enhance spatial flow and daylight.
• Technical Performance
Engineered for structural durability, energy efficiency, acoustic control, and compliance with modern building standards.
• Service Reliability
From early design development to post-installation support, we ensure responsiveness, accuracy, and accountability at every step.
With in-house design consultation, fabrication expertise, and close collaboration with our global and local partners, we tailor every system to the unique needs of each project.
As we grow our presence across Canada and North America, we are actively investing in our dealer and sales network to bring Diba quality to more communities, enabling consistent delivery, localized support, and long-term partnership.
Our Vision
Framing the future of architecture
Our vision is to redefine the benchmark for architectural glazing in North America by becoming the most trusted name in design-focused, high-performance window and façade systems. We strive to lead the industry through an unwavering commitment to innovation, engineering precision, and architectural integrity.
We envision a built environment where every structure, from bespoke homes to large-scale developments, benefits from glazing systems that offer a seamless balance of visual refinement, structural durability, thermal performance, and long-term reliability. Our solutions are not merely components; they are integral to the architectural language of modern buildings.
Through valuable partnerships with globally respected European brands, Diba Windows integrates world-class technology with North American market insight. By expanding our certified dealer and fabrication network, we aim to deliver these systems efficiently, reliably, and at scale.
Our vision is not only to supply premium glazing solutions but to shape the future of contemporary architecture. One project at a time, one collaboration at a time, and one region at a time, we are building a legacy defined by excellence, trust, and transformative design.
Our Core Values
Guiding every detail, from concept to completion.
At Diba Windows, our values guide everything we do. We are committed to design excellence, crafting glazing solutions that elevate architectural vision through clarity, performance, and refined aesthetics. Every system is engineered with technical precision, delivering reliability, seamless integration, and long-term durability.
Sustainability is woven into every decision we make, from energy efficiency to responsible materials, because we believe high-performance buildings should also support a healthier planet. Just as important is our dedication to collaboration. We work closely with architects, builders, and developers to understand their vision and bring it to life with tailored, project-specific solutions.
At the heart of our work is a commitment to building lasting relationships. We value transparency, reliability, and trust, and we see every project as the beginning of a long-term partnership. Our clients are not just customers, they’re collaborators in shaping better spaces.
Finally, our culture of continuous innovation keeps us pushing boundaries, exploring new materials, technologies, and ideas that help redefine what’s possible in architectural glazing.
Our Quality Principles
Built to perform. Designed to last.
At Diba Windows, quality is not just a result, it’s a process embedded in every stage of our work. From design consultation to final installation, our systems are developed with exacting standards and a deep respect for craftsmanship. Every glazing solution we deliver is backed by strict quality control, precision engineering, and performance validation.
We follow a principles-based approach that ensures:
• Consistency – Every unit reflects the same high standard, no matter the scale of the project.
• Compliance – All systems are built to meet and exceed industry codes and building performance standards.
• Craftsmanship – Attention to detail guides every joint, frame, and finish.
• Verification – We test, inspect, and verify throughout the design, fabrication, and installation process.
• Responsiveness – Our team supports clients through post-installation with accountability and care
These principles reflect our promise: to deliver glazing systems that not only look exceptional, but perform flawlessly, today and for years to come.
Sustainability Commitment
Respecting the environment.
At Diba Windows, sustainability is more than a feature, it’s a foundation. We believe great design must also contribute to a healthier planet and a more resilient built environment. That’s why we embed sustainable thinking into every step of our process, from material selection to system performance.
Our glazing systems are engineered to:
• Enhance energy efficiency by reducing heat loss and improving thermal insulation.
• Maximize natural light while minimizing glare and solar heat gain.
• Improve acoustic performance to support healthier, quieter spaces.
• Lower environmental impact through durable, low-maintenance components.
• Align with evolving codes and certifications including NFRC, NAFS, Energy Star, energy codes, and green building standards.
We partner with architects, developers, and builders who share our commitment to responsible design. Together, we create façades that don’t just look beautiful—they help buildings operate more efficiently, last longer, and contribute positively to the communities they serve.
Code Compliance for North American Standards
Performance you can measure, Quality you can feel.
In North America, windows and doors must meet rigorous standards for performance and energy efficiency. Two key frameworks guide this compliance: the North American Fenestration Standard (NAFS) and the National Fenestration Rating Council (NFRC).
NAFS, aligned with CSA A440.2 and adopted by the National Building Code of Canada (NBCC), tests products for air infiltration, water penetration, and structural performance. This standard ensures that all fenestration systems perform reliably under the varied and demanding Canadian climate.
Complementing this, the NFRC provides independent ratings for energy performance, including U-Factor, Solar Heat Gain Coefficient (SHGC), and Visible Transmittance (VT). These ratings are critical for compliance with provincial energy codes and contribute to energy modeling for projects aiming to meet Energy Star, Step Code, or Passive House criteria.
At Diba Windows, our systems are tested and certified under both NAFS and NFRC guidelines to ensure all our products meet or exceed the required standards. Every window and door we fabricate comes with detailed performance data and certification labels, helping builders and architects streamline permitting and inspection processes.
By aligning with these standards, we guarantee not only design excellence and durability, but full regulatory compliance and energy efficiency across North America.
