Universal Series™ Fixed & Operable Windows

Designed and manufactured in North America, the Universal Series™ windows feature an innovative, commercial-grade fiberglass frame boasting up to 250% improved thermal performance compared to traditional aluminum windows. This high-performance design translates into lower heating and cooling costs, as well as a more comfortable and resilient building.

• Environmental Product Declaration (EPD) published under the 2023 Fenestration Assemblies Product Category Rule (PCR)

• Red List Free per Living Building Challenge Declare and Energy-Star qualified
• Offered with double- and triple-glazed Low-E insulated glass units (IGUs)

Fiberglass is an optimal structural material for window and door frames, which is why Cascadia has relied on a proprietary, high glass-fiber-to-resin formulation for over a decade. In addition to its exceptional strength and thermal performance, Cascadia’s pultruded, thermoset fiberglass frames incorporate approximately 58% recycled content, emit low VOCs, and have significantly less embodied carbon than vinyl or aluminum alternatives.

• Offers 100%–250% greater thermal performance than conventional aluminum windows, reducing HVAC energy demand
• Manufactured from high glass-fiber-to-resin, thermoset fiberglass that resists sagging, warping, and creep over time
• Performs reliably in extreme temperatures (−40°F to 350°F and beyond) without becoming brittle or soft
• Comprised of non-organic, chemically inert pultruded fiberglass—resistant to corrosion, rot, UV degradation, and insect damage

• Modeled lifespan of up to 80 years
