The Housing Authority's public housing project, scheduled for completion in 2026, involves a supply of aluminium windows covering an area of 3,600㎡. The project adopts a prefabricated external wall and MEP window integrated design supply solution, tailored to the high-density residential planning of Lok Fu. Standardised window types enhance sound insulation and noise reduction performance, mitigating urban road noise. The aluminium coating resists urban acid rain and UV erosion, suitable for long-term outdoor use; modular prefabricated components simplify on-site installation, aligning with the efficient construction pace of Hong Kong public housing.
