What You'll Need
Ladder
Fiberglass insulation
Dense foam tiles
Acoustical caulk
Isolation clips

Creating a soundproof ceiling is easier than you may think. It does require a bit of time, effort and skill; however, it is certainly a project worth undertaking if you are plagued by constant noise from above. This is not a project you should undertake alone because drywall can be quite heavy. Grab a friend and follow these instructions to soundproof your ceiling.

Step 1 - Expose the Ceiling

Your ceiling must be completely exposed to begin soundproofing it. If there is any drywall or other material underneath, it needs to be removed at this time so that only the wood struts are exposed. Keep the drywall handy and intact in a safe location. It will be easier to use your existing drywall than to cut new sheets. Gather your materials for soundproofing. Be sure to change into a pair of jeans and long sleeves when working on your soundproof ceiling, as fiberglass can be very irritating to sensitive skin.

Step 2 - Pack the Foam

Tightly pack the foam insulation into the spaces between the exposed wooded struts. This is your ceiling’s first line of defense against sound. Generally most normal sound activity can be blocked with R12 or R13 foam insulation. The R index refers to the foam’s density and its ability to block sound.

Step 3 - Seal Small Openings

Inspect your ceiling for any small openings that may need to be sealed. Just a slight space can leak a considerable amount of sound, so use the acoustical caulk to seal any cracks or small holes that you can find. Just a dab on a hole to cover it will be enough to seal it.

Step 4 - Place the Foam Tiles

Place a layer of dense foam tiles over your ceiling. There are a number of companies that sell previously constructed soundproof ceiling tiles. They are your best and easiest option. These type of ceiling tiles will fit into any ceiling without falling loose. Sounds travels slowly through dense objects. Be sure to use ceiling tiles that are as dense as you think you will need to block out your particular sound issue.

Step 5 - Apply More Caulk

Again use the acoustical caulk to seal any cracks or spaces that you can find in the ceiling. Making sure at this stage that the entire ceiling is airtight is very important, so look closely and be thorough.

Step 6 - Replace the Drywall

Replace your ceiling drywall using isolation clips to separate the drywall slightly from the wooden struts and other layers of soundproofing materials. This is called a floating ceiling. It will reduce the noise from vibrations above.

By following these steps, you can create a nicely soundproofed ceiling with just a moderate amount of work. Be meticulous and thorough. Don’t cut any corners, as it just takes a very small space to leech sound through the walls.
