I used this MLV to cover a shared wall and door between my office and another tenant's office. Even though we didn't use any drywall, the effectiveness is astounding. Before you could hear normal conversations clearly. Now, hardly any sound whatsoever. We installed as instructed with roofing nails, vinyl tape, and sealed cracks with Green Glue Sealant. I am extremely impressed with how well this works.
