What are the NCC 2022 installation requirements for 7-star windows and doors?

NCC 2022 Part 8.2.2 mandates specific installation practices for windows and external glazed doors to ensure 7-star energy efficiency and structural integrity. Key requirements include preventing structural loads on the window assembly, maintaining a minimum 10mm gap above, and correct packing to prevent distortion and ensure weathertightness. Adhering to AS 2047:2014 and AS 1288:2021 is crucial for compliance and long-term performance.
