1. A sound-deadening drainage mat, comprising:
a water permeable filter layer;
an entangled net adjacent and joined to the water permeable filter layer, the entangled net having interstitial spaces therein configured and arranged to allow liquid to flow therethrough;
a sound-deadening layer adjacent and joined to the entangled net opposite the water permeable filter layer, the sound-deadening layer configured to reduce or eliminate sound that penetrates an exterior wall cladding;
an adhesive layer coupled to the sound-deadening layer opposite the entangled net, the adhesive layer configured to secure the sound-deadening drainage mat to an interior framing system of a building wall; and
a release layer releasably coupled to the adhesive layer, the release layer configured to be removed prior to placing the sound-deadening drainage mat between the exterior wall cladding and the interior framing system of the building wall;
wherein:
the water permeable filter layer is oriented adjacent the exterior wall cladding,
the sound-deadening layer is oriented adjacent the interior framing system of the building wall,
the entangled net is oriented to allow water to flow through a region between the water permeable filter layer and the sound-deadening layer, and
the water permeable filter layer, the entangled net, and the sound-deadening layer are co-extensive.
