FAQ

Common questions, answered.

What's the benefit of a fixed window over an operable one?

Because the glass is permanently sealed, fixed windows give the best possible wind-load performance and airtightness — ideal for tall openings, stairwells, or anywhere ventilation isn't the priority.

Can fixed windows use thicker glass for extra security?

Yes — glass thickness can be increased for additional strength and wind-load resistance on exposed or high-rise installations.

Do fixed windows still block noise and heat effectively?

Yes — the permanent seal actually gives fixed windows an edge in sound and thermal insulation compared with operable designs, since there are no moving parts to leak through.
