Product Description : High-Performance Acoustical Sealant for STC-Rated Wall Assemblies

QuietSeal® Pro is a high-performance, non-hardening acoustical sealant designed to help optimize the acoustic performance of STC-rated wall assemblies. Applied around wall perimeters, QuietSeal Pro helps prevent noise leaks by sealing gaps that can compromise sound control. Its non-hardening formulation remains soft and flexible to help maintain long-lasting acoustic performance.

Part of the Quiet® family of sound control products, QuietSeal Pro is designed for use with QuietRock® sound-reducing drywall and QuietPutty® acoustical putty as part of the complete Quiet® Sound Damping System. The water-based sealant is low-VOC and low-odor, provides draft and cold-smoke sealing in addition to noise sealing, and cleans up easily with soap and water.
