Soundproof Walls

Good, better, best — at a glance

Each system builds on the one before it: more mass, more damping, and finally full decoupling. Every material links to its product page, and each assembly automatically includes the seam tape and acoustic sealant the install needs.

Good

Regular Studs, Drywall Both Sides, Green Glue One Side

Approx. STC 52

The entry-level upgrade for a standard wood-stud partition: insulate the cavity, then add a Green Glue damped double-drywall face on the noisy side.

Better

Regular Studs, MLV and Green Glue on Both Sides

Approx. STC 56

Mass-loaded vinyl adds limp mass to both faces while Green Glue converts the remaining vibration to heat — a strong non-decoupled wall.

Better

Metal Studs, MLV, Green Glue

Approx. STC 56

Light-gauge steel studs flex more than wood, so the framing itself contributes isolation before mass and damping are added.

Better

Staggered Studs, MLV and Green Glue on Both Sides

Approx. STC 60

Alternating studs on a wider plate mean no stud touches both faces, so the two sides of the wall are structurally separated.

Best

Regular Studs, Putty Pads, A237R Clips, MLV

Approx. STC 60

Resilmount A237R isolation clips and hat channel decouple the drywall from the framing, with putty pads sealing the electrical boxes.

Best

Regular Studs, Putty Pads, A237R Clips, MLV, Green Glue

Approx. STC 63

The A237R clip wall with Green Glue added between the drywall layers — decoupling, mass and damping working together.

Best

Regular Studs, Putty Pads, Isomax Clips, MLV, Green Glue

Approx. STC 62

Isomax clips give a low-profile decoupled face where wall thickness is tight, with MLV mass and Green Glue damping over insulated framing.
