Soundproofing New Ceilings
Whether you simply enjoy peace and quiet or have a noisy upstairs neighbor, you may find it necessary to soundproof the ceilings in your home or apartment. Today we’re going to focus on soundproofing techniques that can be used in a home in which construction is not yet complete.
At the stage of the construction process in which you decide to soundproof your ceilings the wood studs should still be exposed. You’ll need to start by purchasing some sort of fiberglass insulation and packing it into the cavities that exist between the studs.
Science has shown us that mass will block airborne sound waves. Therefore, you’ll need to add some sort of mass to the ceiling. This can usually be done by adding some sort of mass loaded product to the ceiling. The average mass loaded vinyl product is about 1/8 of an inch thick and weighs around one pound for every square foot.
The next step in the process is the application of acoustical caulk. Search for and seal every open joint you can find in the ceiling. Pay special attention to the perimeters of the room.
After you’ve applied the caulk you’ll need to install some whisper clips, also known as isolation clips. These clips will allow you to “float” your drywall away from the ceiling studs. Doing so will allow you to block noises caused by people walking above you, slamming doors, or dropping objects over your head.
The final step in the process of soundproofing your ceiling is to attach your drywall. You can use standard drywall or a sheetrock of your choice but you should not use anything under ½ inch in thickness.
Once you’ve completed this process you should have a soundproof ceiling. Take extra care to ensure you’ve caulked all of the spaces between the joints before installing your drywall. Even a very small hole can cause a significant amount of noise to leak through and it’ll be more effort than it is worth to attempt to correct the problem after the drywall is up and painted over.
