USG Sheetrock® Brand Acoustical Sealant is an acrylic, latex-based sound caulk for use as a sealant in fire-rated partitions, smoke barriers and sound-rated assemblies.
USG Sheetrock® Brand Acoustical Sealant shall be applied in accordance with ASTM C919 using conventional caulking equipment. In joint and firestop systems, apply the USG Sheetrock® Brand Acoustical Sealant to minimum thickness specified in the individual fire-rated system. In shaft wall applications, the maximum separation between bottom of floor and top of liner panel is 25mm. Maximum separation between bottom of floor and top of gypsum board sheets at time of installation of joint system is 16mm.
The joint system is designed to accommodate a maximum 25% compression or extension from its installed width on the finished side of the wall. For all other joints, the sealant application should be specified by a design professional who should give consideration to using a backer rod or bond tape where the gap exceeds 16mm.
For through-wall penetration designs where piping is installed either concentrically or eccentrically within a cylindrical sleeve application, the design professional shall specify a spacer, packing material, or backer rod that is compatible/ non-reactive with both cylindrical outer sleeve and pipe material. The space, packing material, and backer rod shall also serve the function of preventing pipe from contact with the outer sleeve. In joints too shallow to take a backer rod, use a bond breaker tape to prevent three-sided adhesion.

A: USG ME sealants, formulated with an acrylic base, are specifically designed for use in fire-rated partitions, smoke barriers, and sound-rated assemblies as acoustical barriers. They are intended to reduce sound transmission through openings or cracks in walls, ceilings, and floors, providing a versatile solution for various construction applications.
A: USG ME sealants are exceptionally strong and produce a continuous, flexible bead that does not collapse. They flow into even the most complex joints, forming a dense, continuous barrier that effectively blocks out air and other gases. Additionally, these sealants are impervious to water infiltration and offer high thermal shock protection, ensuring optimal performance in sound transmission reduction and thermal insulation.
A: USG ME sealants are perfect for joints in assemblies that are fire-rated but have little to no movement. Their good vibration and movement resistance make them ideal for applications where the joint flexibility is limited, yet high fire ratings and acoustical performances are required. These sealants provide a reliable solution for maintaining the integrity of fire-rated partitions and sound-rated assemblies.
A: USG ME sealants play a crucial role in enhancing the efficiency and effectiveness of fire-rated partitions, smoke barriers, and sound-rated assemblies. By providing a dense, continuous barrier that blocks out air and gases, these sealants ensure the integrity of the structures. Their resistance to water infiltration and high thermal shock protection further enhance their effectiveness, making them essential components in construction projects where sound transmission reduction and fire-rated integrity are critical requirements.
