Soundproofing
Soundproof Ceilings
Isolation-hung and damped ceiling systems that stop footfall impact and airborne noise from the space above — visual assembly guides for every performance tier.
Step 02
Assembly examples
Layer order matters. Compare tested ceilings systems side-by-side and see how each performs.
Good
Green Glue, A237R Clips & Channels, Rockwool
Approx. STC 54 / IIC 55
The baseline decoupled ceiling: Rockwool in the joist bays, Resilmount A237R clips and hat channel to break the structural path, and a Green Glue damped double drywall face.
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.
Best
MLV, A96R Clips & Channels, Rockwool, 2x Green Glue, Acoustic Sealant, Plywood
Approx. STC 67 / IIC 65
Our deepest ceiling: heavier-rated Resilmount A96R clips, plywood and MLV mass, Rockwool fill, two Green Glue damped interfaces and a fully sealed perimeter.

Fundamentals
Core principles of soundproofing
Every assembly on this page combines these five principles. The tier you choose is really a decision about how many of them to layer in.
- 01
Mass
Heavier layers resist and obstruct sound passage.
- 02
Absorption
Insulation reduces and absorbs cavity resonance.
- 03
Damping
Green Glue converts vibration into trace heat, diminishing the wave.
- 04
Decoupling
Clips, channels, and separation break direct vibration transfer.
- 05
Sealing
Airtight gaps, seams, outlets, and perimeters block sneak paths.
