A curtain wall is a non-structural exterior wall that is designed to keep out the weather and support its own weight. It is often made of lightweight materials such as glass, aluminum, or steel, and is typically used in high-rise buildings to provide an aesthetically pleasing and energy-efficient enclosure. Here is a breakdown of the typical content found in a curtain wall detail:

1. Mullions and Transoms:

   • Mullions: Vertical members that provide support to the curtain wall.
   • Transoms: Horizontal members that connect mullions and provide additional support.

2. Glass Panels:

   • Specification of the type of glass used (e.g., insulated, laminated).
   • Glass thickness and color if applicable.
   • Details on any coatings or treatments applied to the glass for energy efficiency or other purposes.

3. Frame Material:

   • Specification of the material used for the framing (e.g., aluminum, steel).
   • Finish details (e.g., anodized, powder-coated).

4. Sealants and Gaskets:

   • Information on the type of sealants used to provide weatherproofing.
   • Gaskets used for thermal insulation and sealing.

5. Thermal Breaks:

   • Details on any thermal breaks incorporated into the framing to reduce heat transfer.

6. Spandrel Panels:

   • Non-vision panels often found at the slab edges or between vision glass.
   • Material specification and finish details.

7. Connection Details:

   • How the curtain wall is anchored to the building structure.
   • Expansion joint details if required.

8. Water Drainage System:

   • Design and details of the drainage system to prevent water infiltration.
   • Location and type of weep holes.

9. Air and Vapor Barriers:

   • Details on any air and vapor barriers used to prevent unwanted air and moisture infiltration.

10. Integration with Other Building Systems:

    • Details on how the curtain wall integrates with other building systems such as HVAC, lighting, and electrical.

11. Structural Considerations:

    • Information on the structural analysis and support provided to the curtain wall.
    • Load-bearing considerations.

12. Safety Features:

    • Details on any safety features incorporated into the curtain wall design, such as fall protection or impact resistance.
