Today’s busy households can be a very noisy place with sound transferring from room to room. When building or renovating, adding acoustic batt insulation to interior walls, ceilings and floors is an effective way to reduce unwanted sound in your home. This insulation is designed to fit tightly between studs and joists in order to absorb sound that would otherwise travel through framing.
It’s critical that you leave no gaps since the smallest space can lower sound-reducing performance. Use acoustic sealant to fill any gaps you may have. Acoustic sealant is engineered for soundproofing and is durable enough to protect gaps and holes for a longer duration than regular caulk. If you want more soundproofing, install two layers of drywall on top of your insulated wall.
