A:  Hello Vans, There is no perceived benefit of compressing a thicker insulation into a smaller wall cavity. However, installing a thicker insulation into a cavity without compressing (ex. 5.5” batt into a 2x6 vs. 3.5” batt) could provide additional noise control. In floor cavities we recommended installing insulation up to 6.25” thick. While adding thicker insulation in a larger cavity can add additional noise control after about 6” of insulation it starts to become a diminishing return and the human ear typically cannot pick up the difference. The amount the STC increases will be based on all components within the assembly. If you are looking fort he STC rating for your assembly, please contact Owens Corning at 1-800-Get-Pink and an Insulation Agent should be able to assist. Thank you for your inquiry!
