Universal Series™ Window Wall

The Universal Series™ Window Wall offers a patented, high-performance full-façade glazing system.

Patented Commercial Fenestration

High-Performance Window Wall

The world's first fiberglass window wall, the Universal Series™ Window Wall is based upon the standard Universal Series™ window system, then augmented with additional components to provide a full-facade high-rise glazing system.

Designed and manufactured in North America, the Universal Series™ Window Wall allows developers and architects to dramatically improve the overall thermal performance of buildings, without sacrificing glazing area.

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
