This method covers the surveying, anchoring, lifting, installing, and sealing of prefabricated unitized curtain wall panels, typically one story high and one module wide. 2. Pre-Installation Requirements Surveying:
Upon completion of the full elevation:
Ensure clear access for cranes or monorail systems and designate a "level-by-level" storage area to minimize double handling. 2. Typical Installation Sequence Step 1: Hoisting and Lifting unitized curtain wall installation method statement
A unitized curtain wall is a type of exterior cladding system that consists of pre-assembled units, typically made of aluminum or steel frames, glass or other infill materials, and anchoring systems. These units are manufactured in a factory and transported to the construction site, where they are assembled and installed to form the exterior envelope of a building. Unitized curtain walls are designed to provide a weather-tight seal, structural support, and insulation, while also offering a sleek and modern appearance. Unitized curtain walls are designed to provide a
"Oil Canning" (visible distortion of flat aluminum). Cause: Over-torqued fixing bolts pulling the frame. Solution: Loosen bolts and re-torque with a load-spreading plate. glass or other infill materials
