Understanding Curtain Wall Systems
Curtain wall systems are vital in modern architecture. They offer both function and beauty to buildings. These exterior walls protect against weather and provide insulation without bearing structural loads.
Let’s explore the key aspects of curtain wall systems. We’ll look at their definition, components, and types.
Definition and Components
Curtain walls are exterior cladding systems that hang from the building structure. They typically use aluminium framing with glass infill panels.
The main curtain wall components include:
- Mullions (vertical members)
- Transoms (horizontal members)
- Glazing (glass or other infill materials)
- Gaskets and sealants
- Anchors and fasteners
Historical Development
Curtain walls originated in the 19th century. Their widespread use began in the mid-20th century. Early examples used steel frames.
Modern systems mostly use aluminium. It’s lightweight and resistant to corrosion.
Types of Curtain Walls
Curtain wall systems are grouped by construction methods and water management strategies.
- Construction methods:
- Stick curtain walls: Assembled on-site piece by piece
- Unitised curtain walls: Pre-fabricated panels installed as complete units
- Water management:
- Water-managed systems: Direct water away from the building interior
- Pressure-equalised rainscreen systems: Use air pressure to prevent water ingress
Each type offers unique benefits. The choice depends on building height, climate, and project needs.
Knowing these systems is crucial for South African architects and builders. It helps create efficient and striking structures.
