Noiseproofing Sealant

Green Glue Noiseproofing Sealant: The Critical Finish for Soundproof Spaces

Even the best-insulated wall will fail if tiny cracks or gaps are present. Green Glue Noiseproofing Sealant is a specially formulated acoustic caulk designed to plug these "sound leaks."By sealing joints between drywall sheets, around electrical outlets, and along floor or ceiling perimeters, you stop airborne noise from bypassing your soundproofing layers. This sealant stays permanently flexible after drying, ensuring it won't crack due to the natural settling or movement of the building.

Key Features:

• Stops Noise Leaks: Effectively seals gaps to maintain the high STC (Sound Transmission Class) ratings of your walls and ceilings.

   

• Permanently Flexible: Unlike standard caulk, it remains rubbery to provide an airtight seal that withstands structural shifts.

• User-Friendly Application: Fits into standard large-format caulking guns for fast, professional results.

   

• Paintable Finish: Can be painted over after approximately 48 hours to blend seamlessly with your interior design.

   

• Safe & Low-VOC: Water-based formula with low odor, making it safe for use in residential and commercial environments.
