Unitized Curtainwall
Male and female mullion and transom system, silicone-glazed for a seamless, factory-finished façade.
The 3D assembly shows the male/female mullion and transom grid that defines this system: coupled vertical profiles form the primary structural joint, a mid transom supports the glazing zone, and structural silicone seals complete the external glazed joint.
System Reading
- Male + female mullion — Coupled vertical profiles form the primary structural joint.
- Mid transom — Horizontal 199 mm-deep profile supports the glazing zone.
- Insulated glazing — Double-glazed units are coordinated at mullion and transom.
- Structural silicone seals — Glazing mounts, silicone, and weather seals create the external glazed joint.
Key Set-Out — Mullion Section
The vertical mullion section coordinates the double-glazed unit.
Load + Seal Path — Transom Section
The mid-transom section supports the same coordinated insulated glazing unit.
- 39.52 mm IGU — 10 mm glass + 16 mm cavity + 13.52 mm glass.
- Mid transom (9620025) — 199 mm profile depth with a 252.5 mm overall build-up.
- PVC glazing frame (238613) — Coordinates the central glazing joint.
- Glazing mount (298968) — Supports the glass edge at the transom.
- Seal package — Structural silicone, gasket 244775, and weather seal.
Standardised Design
Both the mullion and transom details use the same 39.52 mm insulated-glass configuration — the identical build-up applies at every glazing zone across the façade.
Speak to Our Technical Team
Coordinate the mullion and transom before final approval — verifying 39.52 mm mullion and transom glazing along with gasket, glazing-frame, mount, and structural-silicone compatibility. Our technical team can issue the coordinated vertical mullion and horizontal transom sections for your approval.
