a sufficient level of sound insulation in wooden buildings can usually be achieved structurally by using multi-layered constructions. by positioning porous absorption material behind the board or panelling in addition to an air gap, for example a layer of thermal insulation, a so-called board resonator is formed which, when it.
korlok is easy to install over most existing hard floors and imperfect subfloors, and the pre-attached acoustic backing means there is no need for a separate underlayment, saving on time, labor and materials costs. with excellent acoustic properties (iic rating of 62), korlok reduces noise transfer to rooms below, making it.
the grena company can provide supplies and installation of materials for various designs of concert halls, studios, theatres and cinemas. our materials have very good acoustic properties and are available in a wide range of finishes and shapes. typical composition of acoustic panels made from grenamat boards.
