Fiber glass insulation is effective at reducing unwanted sounds from appliances, TVs, stereos and ventilation systems. For a quieter home environment, install fiber glass insulation in some or all of the interior walls, ceilings and floors of your home. This includes bathrooms, bedrooms, entertainment rooms, home office areas and kitchens. You not only benefit from increased peace and quiet, you also add lasting value.
CertainTeed has a sound control batt specifically designed for interior wood-stud walls called NoiseReducer™.
You can get better results by insulating heating and air conditioning ducts and water pipes. Metal ducts may be wrapped in insulation, or you can install rigid fiber glass insulation duct board.
