A curtail wall mullion detail refers to the way in which the vertical members, called mullions, of a curtain wall are connected to the building structure. These details are typically shown in architectural drawings, and they specify the type of connection, the materials to be used, and the dimensions of the members.
The exact details of a curtail wall mullion will vary depending on the specific project, but some common elements include:
- Anchor plates: These are typically made of steel and are used to secure the mullions to the building structure.
- Seals: These are used to create a weather-tight seal between the mullions and the building structure, and between the individual panels of the curtain wall.
- Mullion profile: This will depend on the type of curtain wall system being used. Some systems use aluminum extrusions for the mullions, while others may use steel or other materials.
- Connection type: This will depend on the type of building structure and the load-bearing requirements of the curtain wall. Some common types of connections include bolted, welded or mechanical connector.
It’s important to mention that the design of a curtain wall mullion detail should be done by a professional with experience in this field.

A typical curtain wall mullion detail drawing is a technical drawing that shows the specific design and construction details of the mullions of a curtain wall. These drawings are usually included as a part of a set of architectural or engineering drawings for a building project, and are used by contractors, fabricators, and installers to understand how to properly construct the curtain wall.
The details in the drawing will depend on the specific project and the curtain wall system being used, but typical information that may be included in a curtain wall mullion detail drawing are:
- Dimensions of the mullions and the connection points to the building structure
- Material specifications for the mullions, anchor plates and seals.
- Type of connection (bolted, welded or mechanical connector)
- Details of the weather seal, thermal breaks, and other performance-related elements of the curtain wall.
- Fastener schedule, which list all the necessary fasteners (screws, nuts, etc) and their location on the curtain wall
- Load carrying calculations and specific requirements
It’s important to note that these drawings should be prepared by a professional with experience in curtain wall design, and should be reviewed by a structural engineer to ensure that the design meets the appropriate safety codes and standards.
