Match window operation to the room and opening
Compare how an operating type affects ventilation, reach, cleaning, clearance, safety, and the written project scope.
What is not established
- No operating type is recommended for a specific room or person.
- Local rules and actual clear openings, hardware, reach, exterior obstructions, and maintenance access remain unknown.
- The local collection does not establish local availability, approval, service coverage, or project suitability.
Describe the needed action
- Fixed or picture: daylight and view without opening ventilation
- Awning or casement: outward-swinging operation that requires exterior clearance
- Single-hung or double-hung: vertical sash movement with configuration-specific cleaning and opening details
- Sliding or gliding: horizontal sash movement with track, reach, and clear-opening considerations
- Bay, bow, corner, direct-glaze, and specialty forms: assemblies whose support, water management, and configuration need exact review
A type name does not prove emergency-escape compliance, accessibility, fall protection, safety glazing, ventilation capacity, or compatibility with an opening. Record these as verification questions.
The product-family pages identify example operating types. Current type availability and every dimension or option remain configuration-specific.
