Cascadia Windows & Doors was founded in Langley, BC, by a collective of building science and window specialists in 2008. Having supported hundreds of building owners through the Leaky Condo crisis in the Pacific Northwest over the previous decade, Cascadia’s founders knew first-hand the downstream effects of poor building performance. However, as building envelop design improved as a response to the crisis, they anticipated that buildings would also need to prioritize the energy performance of their fenestration systems and that a new line of products would need to be developed to address the issue.
This realization was the initial spark that led to Cascadia’s founding, but the guiding principles of the company have always focused on innovating, commercializing, and producing the most energy-efficient windows and doors on the market. For over 15 years, this BC success story has done exactly that. Regularly recognized by architecture and building science organizations for their novel and highly technical approach to window and door design, Cascadia’s products continue to disrupt the largely static window industry.

Their new Cascadia Clip represents an evolution in the company’s push to develop novel solutions for cladding systems based on passive principles. Applicable for use in steel frame, concrete, and wood construction buildings, the Cascadia Clip’s innovative fiberglass design reduces thermal bridging between traditional steel cladding supports and the back-up wall, while still offering comparable structural performance when compared to traditional products. Carrying a comprehensive IAPMO code evaluation, the Cascadia Clip allows architects and specifiers to design thinner, lighter and more cost-effective exterior cladding solutions, while at the same time drastically improving a building’s overall energy performance.
Spotlight on: PAE Living Building
PAE Engineers’ offices in Portland, Oregon. As Kathy Shaloo Berg of ZGF Architects noted during one of our Project Showcases, the office is the world’s first developer-driven Living Building and relies on passive principles (like exceptional fenestration systems) to optimize energy performance.

It’s also really great to partner with a firm that is so dedicated to energy performance and finding innovative ways to reduce the embodied carbon of their products.”
“We’re excited to partner with the Accelerator,” said Mike Battistel, President of Cascadia. “High-performance windows are fundamental to Passive House construction and design, and that’s actually why we created the first, North American designed window to achieve Passive House International Certification. We knew we could provide cost-competitive, commercial-grade fiberglass windows and doors that offered unparalleled thermal and structural performance compared to traditional vinyl and aluminum products.”
Passive House Accelerator Founder Michael Ingui noted that the partnership will be a boon to other architects who are seeking out more North American options for Passive House certified components. “Cascadia makes truly exceptional products and those within the Accelerator community are going to really enjoy learning about them,” he said. “They are always looking for more options when it comes to thermally broken windows, doors, and cladding systems.”
