Curtain walls, also known as curtain glazing systems or modern glazed facades, are non-structural facades that consist of aluminum frames and glass panels. They are designed and installed following a series of steps:
1. Design: First, the architect or engineer designs the curtain wall system to ensure its suitability for the building. The design process involves selecting the type of glass, aluminum framing, and other components that fit the project's aesthetic and performance requirements.
2. Fabrication: The curtain wall system's components are then fabricated, including glazing panels, aluminum frames, and other accessories, such as weather seals or fire safety systems.
3. Installation: The curtain wall system is installed on the building's exterior by attaching it to the main structure. The installation process begins with the framing, which supports the weight of the glass or other infill panels. The frames are anchored to the building's concrete or steel structure, and installation continues with attaching the various components, such as glass panels, seals, and insulation.
4. Sealing and weatherproofing: Once the curtain wall system is installed, sealants and gaskets are used to ensure that the system is watertight, airtight, and thermally efficient. The installation team will also test the system for air and water infiltration and fix any issues that arise.
5. Finishing: The final step in the installation process is the finishing, which involves applying any necessary coatings or finishes to the aluminum framing and other components to provide protection against weathering and corrosion.
Overall, curtain walls are typically installed by skilled professionals, such as glaziers or cladding contractors, who have the necessary expertise and equipment to handle the installation safely and correctly.
