There are many specialized products on the market, including sound control doors and wall and ceiling applications, that are used for soundproofing, noise control, acoustical, and vibration problems. For the home applications, blown-in cellulose insulation is the best option that will be available in most locations. The application of blown-in cellulose is what makes it perform better than fiberglass insulation. When installed, rolls of fiberglass insulation do not get into all of the voids and odd angles. Heat and sound loss occur through these spaces. Blown-in cellulose has the ability to be sprayed into all of the spaces to stop heat and sound losses. For extremely tight spaces (e.g. around pipes), spray foam insulation can assist in preventing heat and sound loss. Important note: There needs to be a 1-inch gap between the concrete wall and the blown insulation when insulating the basement. This is achieved by attaching a mesh to the furred out stud walls, so that the insulation does not go all the way to the concrete wall. This is done so that there is no moisture buildup behind the insulation (resulting in potential mold growth).
