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
