The Challenge
Why This Product Exists
Architects want maximum glass and minimum frame, but operable window hardware requires wider profiles that reduce the glass area and create visual bulk. In many locations — above doors, in stairwells, in combination with operable windows — opening functionality is unnecessary, yet standard operable frames are specified by default, wasting budget and compromising aesthetics.

Common Questions
Frequently Asked Questions
Fixed windows offer 15-20% more glass area than equivalent operable windows, better thermal performance (no seals to degrade), lower cost, and zero maintenance. They are the optimal choice wherever ventilation is not required.
Yes. Fixed windows are commonly combined with casement, tilt-turn, or awning windows in mullion-connected configurations. This provides ventilation where needed while maximizing glass area and views elsewhere.
