Soundproof Ceilings

Good, better, best — at a glance

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

Good

Green Glue, A237R Clips & Channels, Rockwool

Better

A237R Clips & Channels, Rockwool, 2x Green Glue, Acoustic Sealant

Better

MLV, A237R Clips & Channels, Rockwool, 2x Green Glue, Acoustic Sealant

Approx. STC 62 / IIC 60

Adds a limp mass-loaded vinyl barrier above the damped drywall stack for meaningful low-frequency gain without changing the framing.
