The site is located under an airport runway. The construction of the house consists of 375 mm thick aerated concrete blocks walls. The design of the house includes 2 facing options:
1. 50 mm mineral wool.
2. 120 mm facing brick with a ventilation gap of 40 mm.
Which cladding option will provide better sound insulation against aircraft noise? Or will it be higher than that of any window in any variant? Which windows should I buy to achieve maximum sound insulation? Is it better to use maximum density aerated concrete, or are D500 and D600 different from each other in terms of sound insulation?
