Fixed windows, also known as picture windows, are non-operable glass panels designed to frame outdoor views while maximizing natural light. Since they do not open, fixed windows offer superior insulation and airtight performance — making them ideal for enhancing energy efficiency and architectural aesthetics.

Often used as feature windows in living rooms, stairwells, or hallways, they can be combined with other operable styles to create striking visual effects without compromising ventilation needs elsewhere.
