High-performance Fiberglass windows & doors

Universal Series High Performance Fiberglass Windows
Future of Performance

Why Fiberglass?

Fiberglass is an ideal structural material for window and door frames, which is why Cascadia has used a proprietary, high glass-fiber-to-resin formula for more than a decade. Beyond its high strength and thermal efficiency, Cascadia's pultruded, thermoset fiberglass frames contain roughly 58% recycled content, low VOC's and represents less embodied energy compared to vinyl or aluminum.

Technical Focus

Uncompromising Design

When the technical team at Cascadia Windows & Doors set out to create a next-generation, high-performance fenestration solution, they started with a long list of objectives. Passive House level thermal performance. Commercial-grade strength. High site tolerance. Easy onsite coupling. Lower costs. The list went on.

But over the next year, the team was able to design, test and manufacture an innovative, fiberglass frame fenestration solution that checked nearly all the boxes. This solution was the Universal Series™. Owing its name to its versatility, the Universal Series™ combined strength and thermal performance, ease of install with durability, and has been recognized by organizations around the world, including the Passive House Institute and Canadian Green Building Council.
