Hopper Configuration
High-Transom Ventilation Engineered for Tight Spaces
The Hopper window is bottom-hinged with the sash tilting inward from the top. It is the standard specification for transom and basement-level openings where clearance is limited and ventilation is critical. Its sealed bottom edge resists water intrusion effectively in below-grade applications.
Primary Applications
- Basement & Below-Grade Openings
- Transom Ventilation Lights
- Mechanical & Utility Rooms
Performance Benefits
- Sealed bottom edge makes it suitable for below-grade and foundation-level applications.
- Compact tilt profile requires minimal interior clearance at the top of the opening.
- Pairs easily with fixed glass above for large-format facade compositions.
