Abstract
A sound damping wallboard for installation on an installed wallboard, a sound damping wallboard system, and a method of constructing a sound damping wallboard on a building structure are disclosed. The sound damping wallboard comprises a gypsum layer having a gypsum layer inner surface and a gypsum layer outer surface, a sound damping layer disposed at the gypsum layer inner surface for installation between the gypsum layer and an installed wallboard and having a sound damping layer inner surface, a first encasing layer disposed at the gypsum layer outer surface, and a second encasing layer disposed at the sound damping layer inner surface.
Claims21
A method for forming a sound damping wallboard, comprising:
- providing a gypsum layer having a gypsum layer inner surface and a gypsum layer outer surface, the gypsum layer having a first encasing layer disposed at the gypsum layer outer surface and a third encasing layer disposed at the gypsum layer inner surface;
- applying a sound damping layer to the third encasing layer such that the sound damping layer includes a sound damping layer inner surface opposite the gypsum layer inner surface;
- and providing a second encasing layer at the sound damping layer inner surface, wherein the second encasing layer is formed of a material comprising paper, fiberglass, foil, or a polymer;
- wherein, when attached to an installed wallboard, the sound damping layer is disposed between the gypsum layer and the installed wallboard.
