Curtain Wall Portal Installation
Architectural curtain wall glass entrances feature heavy laminated double-glazed units and concealed transom closers.
Installation Protocol
- Deep Glass Offset: Calculate the M5 center relative to the structural glazing pocket (typically 30/45 mm or 35/50 mm offset).
- Closer Arm Pre-Load: Adjust the overhead closer sweep speed so the door latches gently without slamming the cylinder against the strike jamb.
