Acoustiblok Sound Sealant is a fire-rated caulk with superior acoustical isolation properties, formulated to bond to Acoustiblok material. All joints and penetrations in Acoustiblok material must be sealed, to obtain rated sound reduction values. Available in 10 oz. and 28 oz. tubes.
Sound reduction installations require as airtight of a seal possible. Provides excellent sealing properties and decouples adjacent surfaces, helping to minimize structural sound transmission. Very flexible and maintains its flexibility over time. Specifically formulated to work with the Acoustiblok Sound Isolation Material.
Acoustiblok® is a 1/8 inch thick proprietary viscoelastic polymer material with a high density mineral content, heavy and yet extremely flexible. As sound waves cause the Acoustiblok material to flex, internal friction occurs (isothermal/adiabatic) and the acoustical energy is dissipated into undetectable trace amounts of heat. A one 1/8 inch layer of Acoustiblok in a standard wall will result in more sound reduction than 12 inches of poured concrete.
