Ceilings
Below you’ll find a compilation of ceiling soundproofing products. The list is arranged by the cost of the solution, from high to low.
Solution: QuietRock
Cost: Very Expensive
Summary: Basically a specially manufactured sheetrock that reduces noise transfer. A positive is that you can hang it just like traditional drywall which should make installation costs very similar to standard drywall. The disadvantage is that it weighs more and can cost 10 times more than traditional drywall. Working with the additional weight during a ceiling installation can be challenging. It is available in a variety of thicknesses from 1/2″ to 1 3/8″. The thicker versions have better sound insulation performance.
Solution: Acoustiblok
Cost: Expensive
Summary: Acoustiblok is a proprietary formulated viscoelastic polymer, which in layman’s terms is a thick sheet of rubbery material. It is pliable and a typical ceiling installation is to attach it directly to the joists before you put your regular sheetrock ceiling up. With a little experience, it is pretty easy to hang. The claimed sound dampening is similar to QuietRock. One nice thing about Acoustiblok is that it can be used on walls, ceilings, and floors, so you can buy in bulk and use it for many different soundproofing applications in your home.
Solution: Closed Cell Foam
Cost: Moderate
Summary: This foam is light and easy to work with. It is typically installed above the ceiling wallboard either between the wallboard and joists or between the joists themselves.
