How to Soundproof a Basement Ceiling

Ceiling

I’m going to finish a portion of the basement for my 12-year-old daughter and her pals to have a place to “hang out.” This section happens to be under the great room on the main floor. Are there products to help in noise reduction, and, if so, what options exist and how are they installed? -Steve

Hi Steve,

Start by insulating the space between the basement ceiling joists with a sound dampening insulation like Owens Corning QuietZone fiberglass insulation. Next, you might want to consider using a soundproofing drywall such as QuietRock for the ceiling.

You can watch and read more about QuietRock, on our website at (622) Builders’ Show Special.

Good luck with your project,

Danny

  1. If the ceiling is already drywalled, consider the addition of another sheet of standard 5/8″ drywall and Green Glue.

    If you have open joists the fiberglass Danny mentioned is great. Consider installing wood furring strips 24″ on center, perpendicular to the floor joists. Attach two sheets of standard drywall to the furring strips (not the joists). Damp the drywall with a product like Green Glue.

  2. There are many ways to isolate vents. Generally the Vents are shielded in some fashion. The vents are also wrapped in insulation, all behind the shielding. This allows the vent to absorb the sound as it travels through the vent.

  3. DIY yourself damping compound like Green Glue will give you better results than the Quiet Rock and will be a nice amount cheaper. If you want to really beef up on your ceiling use whisper clips and hat channel on your joists, than hang the drywall with green glue on the channel.

  4. I would like to chime in with a recommendation of Green Glue as well. The similar performing QuietRock 525 is difficult to install because of the weight of each panel and also the difficulty of cutting through each panel vs. cutting standard drywall.

    QuietRock 525 will perform as advertised, but the extra work and extra cost required typically aren’t worth it to the end user.

  5. QuietGlue is 20% cheaper than GreenGlue.
    QuietRock is a different product and not a damping compound.
    And QuietRock will give better results than green glue. It can’t be compared with quietrock.
    QuietRock has drywall, damping compound and more, which saves a lot of time and work.

  6. i have the same problem, but we have a low ceiling in the basement, right now we have ceiling tile, if i replaced that with a dry wall ceiling, how much noise reduction would that bring? would i need to take more steps for it to be noticable?

  7. Which would be better, using the whisper clips and hat channel, or the two layers of sheetrock and green glue. I am looking at reducing noise in my basement that I am finishing, but didn’t want to do both.

  8. Jesse – The clips would be more efficient at isolating sound overall, especially in a ceiling assembly. If you were to choose Green Glue Compound or the clips then definitely go with the clips.

  9. If I were to install a drop ceiling in the basement, would there be much sound deadening benefit to first installing acoustic insulation between the ceiling joists?

  10. Has anyone heard of a product called acoustiblok? I heard it was supposed to be really good for soundproofing, both keeping noise in and/or out of a room. I also just saw when doing my research that they just released a new product called quietfiber. To me it looks like fiberglass insulation but they claim is contains no fiberglass.

  11. I live in a bottom unit condo and the noise from the condo above is loud and stressful. What can we do to make the ceiling soundproof? We not only hear footsteps, we hear the toilets, shower, bed squeaking, everything except voices.

  12. Hi My room is located in the basement of my hOuse and I could hear all the pounding footsteps from upstairs. My room has a suspended ceiling. Can you give me some easy and cheap DIYs to reduce the sound significantly or atleast make it less annoying. Thank you!

  13. I removed the carpet and padding from my stairs because it would get really filty because of foot traffic. The problem now is that I can hear entire conversations from downstairs. The ceiling in the closet that is below the stairs is not insulated. It is a fully finished basement and the rest of the ceiling is insulated. What do you suggest to get rid of the noise? I do not want to put padding and carpet on the stairs.

    Thank you,

  14. I’ve read all the pros and cons to insulate (keep basement noise in the basement). What I really need now is a qualified installer to do the job. I cant seem to find one in Cobourg, Ontario area. Can any body help?

  15. My family just bought a new ski house. The bedroom where the teenagers sleep is in on the bottom floor, right below the kitchen. In the morning, as soon as people start walking around in the kitchen I wake up. Is there anyway to renovate the floor between the second floor and basement to limit the sound in the basement bedroom a little bit?
