Sound board is a non-structural acoustic underlayment panel installed between framing and the finish layer of drywall. It adds mass and a resilient, less rigid layer to a wall or ceiling assembly, which helps break the direct path that airborne noise takes through a partition.

The panel is soft and easily cut with a utility knife, and it is fastened to studs or joists before the finish board goes on. Because it is not a finish surface and carries no structural load, it is always covered by gypsum panel, which takes the joint treatment and the final decoration.

It is a common choice in retrofits and partition upgrades where a quieter room is wanted without rebuilding the framing or adding a second stud wall.

Key Features

• Non-structural acoustic panel used as an underlayment beneath gypsum board
• Adds mass and a damping layer to wall and ceiling assemblies to reduce airborne sound transmission
• Standard 4 ft. by 8 ft. panel format matches common framing layouts and drywall sheet sizes
• Soft board cuts cleanly with a utility knife and straightedge
• Fastens directly to wood or metal framing before the finish layer is installed
• Intended to be covered by drywall rather than finished or decorated directly

Applications

• Sound-dampening layer in interior partition walls between rooms
• Ceiling assemblies below bedrooms, bathrooms and mechanical spaces
