Universal Series™ Fixed & Operable Windows

The Universal Series™ offers a patented, high-performance fiberglass solution for fixed and operable windows, as well as doors, storefront and window wall.


Patented Window Design

Better Windows. Better Buildings.

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.


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.

  • Boasts 100%-250% improved thermal performance compared to traditional aluminum windows, lowering heating and cooling costs
  • Made from high resin-to-glass, thermoset fiberglass, the windows will not sag, weaken or creep over time
  • Can withstand extreme temperatures (-40°F through 350°F, and higher) without becoming brittle or soft
  • Made from non-organic, chemically inert pultruded fiberglass, the windows are not susceptible to corrosion, rot, insect damage or UV degradation
  • Modelled lifespan of 50-80 years
