How to Soundproof New Construction

Wall assemblies are the primary barrier for airborne sound. In new construction, this is the ideal time to incorporate decoupling, damping, and added mass.

Using RSIC™ Resilient Sound Isolation Clips decouples drywall from framing, reducing sound transfer. Use mass loaded vinyl for blocking airborne noise with mass. Apply Green Glue Noiseproofing Compound between drywall layers to add damping to reduced noise transfer.

If you want to explore different sound isolation clips and hangers, compare options before finalizing the assembly.

Floor assemblies must control both airborne and impact noise. For multi-story buildings, this directly affects IIC rating performance.

Installing UnderBlock™ Rubber Floor Underlayment beneath finished flooring reduces structure-borne vibration and improves impact insulation. Adding carpet further increases absorption and impact reduction.

Ceilings are especially important in multi-family and hospitality projects. Whether you’re separating units or preventing noise transfer between levels, ceiling assemblies mirror wall strategies.

Installing RSIC™ Resilient Sound Isolation Clips with double drywall and Green Glue Noiseproofing Compound creates strong isolation. Insulation within the joist cavity further improves performance.

Windows are common weak points in exterior walls. Even well-built assemblies lose performance through glass openings. Adding Soundproof Window Inserts creates an additional air gap and sealed layer, improving blocking performance.

If you have any interior windows built into the spec, Tru Acoustics Soundproof Windows provide the best soundproofing you can find.

Doors are often the weakest link in otherwise strong assemblies. A hollow-core door can drastically reduce overall STC performance.

At minimum, use a solid core door combined with a Sound Lock Acoustical Door Seal Kit to eliminate perimeter gaps. For maximum isolation, install the Sound Lock STC 56 Soundproof Door.
