Upgrading Your Ceiling with Green Glue

This solution adds an additional TWO layers of standard 5/8” drywall to the existing drywall or plaster ceiling. This makes the ceiling quite a bit more massive (an additional 8 pounds per square foot) and again utilizes standard $8 drywall. Install a medium coverage of Green Glue between layers. This will damp more vibration, but still not all, since the vibration is still racing through the framing (joists) above the new drywall layers, with some of this energy still available to enter your ceiling as well as walls.

Ease and Cost

• Inexpensive
• Simple
• Fast
• The only issue is accurately finding the existing joists

Performance

• The standard ceiling upgrade is a basic level of improvement. It does not address the vibration that remains in the subfloor and joists overhead, and therefore does not reduce the vibration that may flank from the upstairs floor directly into your walls. It will reduce airborne noise more than it will reduce the impact noise.
