Acoustical Insulation Installation

The most common sound insulation used in residential construction is unfaced fiberglass batts applied in interior walls and between floors for deadening sound.  Roxual batts can be used in these same areas also.  An upgrade for interior sound deadening for a home theatre room would be to use Roxul batts with semi-rigid fiberglass board.  We at J & L Insulation highly recommend that all the interior walls and floors be insulated for the best thermal and acoustical performance in a home.
