Pil writes from Edgewater, New Jersey: "How can i help improve insulation of an existing room and would that also help better sound proof the room from noise from outside of the room?"

Answer: Owens Corning manufactures PINK FIBERGLAS™ insulation products for both thermal and acoustical control. The company does not manufacture a specific wall treatment product for your application. To use fiberglass insulation it will be necessary to remove existing wall finish (drywall), then insulate the framing of the wall (2x4 studs) and install new drywall. If you are insulating exterior walls, we recommend using faced insulation with an R-value of 13 or 15. Using FIBERGLAS insulation in the wall cavities will also help with noise control. Install the insulation with the vapor retarder facing the warm-in-winter side.
