Estimating the term…
A laminated structure for use in retrofit building construction (partition, wall, ceiling, floor or door) that exhibits improved acoustical sound proofing characteristics while being optimized for efficient installation. The laminated structure includes a panel with at least one layer of viscoelastic glue, or fire-resistant, viscoelastic glue, which functions both as a glue and an energy dissipating layer. In one embodiment, the laminated structure to be attached to an existing wall in some embodiments includes standard paper-faced gypsum board. In another embodiment the to-be-applied laminated structure includes a cement-based board, and in yet another embodiment the to-be-applied laminated structure includes a cellulose-based board. Once the laminated structure is installed on an existing wall or other partition, the resulting structure greatly attenuates transmitted noise and minimizes the labor required for installation and finishing.
