Airborne Noise From Above - Existing Drywall Removed

Primary Suggestion: Resilient Sound Clip System

Here's what you will need:

• GenieClips
• 25 gauge furring hat channel
• Insulation for joist cavity if it is not already insulated
• Acoustical sealant for ceiling perimeter
• Single or double layer drywall (double layer drywall will double performance without requiring additional clips)
• Option: Include Green Glue Compound between double drywall to increase isolation further

Rating: Estimated at 54 STC and 51 IIC.

Cost: Estimated at about $1.15 per square foot plus the cost of drywall (typically .25 cents per square foot) and plus the cost of labor.

Secondary Suggestion: Green Glue Compound Damping System

Here's what you will need:

• Green Glue Compound (1 tube per 16 square feet of ceiling)
• Two layers of drywall (5/8" recommended)
• Insulation for joist cavity if it is not already insulated
• Acoustical sealant for ceiling perimeter

Rating: Estimated at 46 STC.

Cost: Estimated at about $.95 per square foot per Green Glue Compound layer plus the cost of drywall (typically .25 cents per square foot) and plus the cost of labor.

DO NOT USE mass loaded vinyl, sound board, resilient channel, acoustic foam, specialty insulation, or any other similar product to isolate airborne noise from passing through your ceiling from the room above. These products are not effective enough to significantly improve isolation in your ceiling.
