Abstract
An acoustic insulator is provided. The acoustic insulator includes a corrugated layer and a facer layer. At least one of the corrugated layer or the facer layer is an acoustic paper having a basis weight of 32 g/mto 540 g/mand an airflow resistance of 500 mks rayls to 2,500 mks rayls. The acoustic insulator is effective for attenuating low frequency noise and exhibits excellent fire resistance.
