Engineered to withstand harsh Canadian winters and optimized for modern architectural aesthetics.
The demand for high-performance building materials in Canada has never been higher. As urban centers like Toronto, Vancouver, Montreal, and Calgary continue to expand, the architectural landscape is shifting towards modern, sustainable, and highly durable solutions. Aluminum casement windows have emerged as a dominant force in both commercial and high-end residential sectors across the country. Unlike traditional materials, advanced thermally broken aluminum offers the structural integrity required for massive glass panels while meeting Canada's stringent energy efficiency codes.
Canada's diverse and extreme climate—ranging from the freezing, heavy snowfalls of the Prairies and Quebec to the damp, salty coastal winds of British Columbia and the Maritimes—demands fenestration products that will not warp, crack, or degrade. Modern aluminum window manufacturers have revolutionized the industry by integrating polyamide thermal breaks and multi-chamber profiles, effectively eliminating the cold transfer historically associated with metal frames. This technological leap has made aluminum the material of choice for architects pursuing Net-Zero building standards and LEED certifications in Canada.
Engineered to prevent condensation and frost buildup during severe Canadian winters, ensuring structural stability from -40°C in Edmonton to coastal storms in Halifax.
Meeting the demand for slim sightlines and maximum daylight in modern high-rise condos and luxury custom homes across Vancouver and Toronto.
Designed to exceed the requirements of the National Building Code of Canada (NBC) and provincial standards, featuring advanced Low-E glass and argon gas fills.
The versatility of our aluminum casement windows allows them to be seamlessly integrated into various Canadian architectural contexts. In the bustling metropolis of Toronto, developers utilize our high-STC (Sound Transmission Class) rated casement windows to block out urban noise while maximizing skyline views in luxury condominiums. In Vancouver and Victoria, where moisture and ocean air are constant factors, our corrosion-resistant powder coatings and anodized finishes prevent oxidation, maintaining a pristine look for decades.
Furthermore, in custom home builds in regions like Muskoka or Whistler, large-format aluminum casement and tilt-turn windows are utilized to frame breathtaking natural landscapes. The inherent strength of aluminum allows for narrower frames and larger glass expanses compared to vinyl or wood, perfectly complementing contemporary Canadian design philosophies that emphasize indoor-outdoor connectivity.
DERCHI provides one-stop, custom aluminum door & window solutions tailored for complex global projects. With a massive manufacturing footprint and cutting-edge technology, we have the capacity and expertise to supply high-volume commercial developments and bespoke residential builds across Canada and North America.

One-stop customization: From structure and style design to private whole-home solutions, we offer personalized colors, specialized glass configurations, premium hardware, and durable finishes. We provide full project coordination from the initial design phase to final delivery, ensuring seamless integration into your Canadian construction schedule.
We hold over 100 national patents, including the innovative Four-Side Six-Point Lock system. Our commitment to quality is backed by international certifications essential for the North American market, including CE, NFRC, AS2047, CSA (Canadian Standards Association), Energy Star, and ISO 9001.
For coastal Canadian regions susceptible to extreme weather, structural integrity is paramount. DERCHI doors and windows are certified to meet rigorous hurricane performance standards. Our products have successfully passed the ASTM E1886/E1996 tests, assessing impact resistance against flying debris and structural performance under severe cyclic wind pressure.
We have also obtained the Miami-Dade NOA (Notice of Acceptance), the most stringent hurricane certification globally. This guarantees exceptional performance in high-wind zones. We work with accredited third-party testing agencies like Intertek to verify product performance, ensuring full compliance with structural, water-tightness, and air-tightness standards (including AAMA certification).
