Our basement gets a ton of use. I make videos at my home office, and my son has set up a recording studio, so sound needs to be managed. Sounds from upstairs are coming in the basement, and the saxophone, drums, and keyboard can be heard throughout the house as well. I plan to use a combination of ROCKWOOL and Homasote plus a few sealants to create an environment where sound is better managed.
We interviewed @homasotecompany5059 at the international builders show this year, and they shared some wall and ceiling details with us.
