I live in a upper unit of a 2 floor house. The house was originally designed as a single house
Its a rental. I would like to advice on a ways to reduce the sound
of the tenant below. Im trying to block voice, TV and refrigerator hum.
Which product would you recommend under the new carpeting.
I have located the products below for sound reduction
QEP 1/2 in. Natural Cork Underlayment for Sound Reduction, 2 ft. x 3 ft. Sheets, (25 Sheets)
Model # 72001
Internet # 202501820
QEP Natural Cork Underlayment is ideal for reducing sound transmission from upper levels to lower level living spaces. Under ceramic tile, on a 6 in. slab with a suspended ceiling in the floor below the acoustical ratings for the 1/2 inch cork are STC 89 and IIC 88. These ratings are outstanding since architects typically require minimum ratings in the 50’s. Natural Cork Underlayment can be used under ceramic tile, porcelain tile, stone, marble, engineered hardwood and laminate floors. Natural Cork Underlayment also acts as a crack isolation membrane that resists the transfer of cracks from the subfloor into cracked tiles on the finished floors. Natural Cork Underlayment also reduces thermal transmission, increasing the effectiveness of floor heating systems. Natural Cork Underlayment is easy to install with Roberts Cork Underlayment Adhesive.

Hey again fredbelgium,
I just wanted to let you know that I already answered your question regarding sound reduction for your office.
Click here and it will take you to your other post.
And again, let us know if you need anything else regarding this project.
Hi! I am working in an old Victorian building in San Francisco. I am a psychotherapist who needs calm to work with clients. The landlord is installing a small wine bar underneath my office. He has put a double layer of sheetrock on the ceiling of the wine bar to block the noise. He is planning on putting new carpet in my office with some insulation. He has tried it in other offices and from what I see, he has used recycled rubber tires in one of the offices and it smells very bad. I have two questions: will the double sheetrock layer be enough? What is the best insulation to put underneath the carpet?
I don't want any noises or smells. I am afraid the rubber tires smell is toxic. Thank you!
Hi again stev,
Yes I did realize your situation with it being an upper floor and wanting the best sound reduction to lay down, rather than installing a complex system.
Once you've taken out all the existing old carpet, tack strips, and any transitions, you'll need to make sure the wood subfloor is clean and level.
And yes, using cork underlayment as we talked about would most definitely work. In terms of their installation, they come in 2ft. x 3 ft. sheets, as stated in the image that was posted. Having something in a roll versus a sheet won't make any difference in its performance. How you adhere and fasten it down however will determine how well this and any product will work.
As for using Green Glue Noiseproofing Compound, it is an item that I haven't heard of until you spoke of it!
I looked at their website, and although I am not familiar with the product, I'd recommend contacting them to make sure that the cork underlayment can and will work if it is being applied with this. Since it's not sold in our stores (at least in my area), I can't make an accurate judgement call on it, only our adhesives that we sell.
The glue that I recommended originally is a water-based and safe product to use, but if Green Glue will work for your cork underlayment panels, then there should be no worries for your installation.
And lastly, remember that a good carpet padding will also reduce sound as well, just something extra to consider.
Hopefully, this and helped you out and my hats off to you for researching additional information and materials. With what you know now, you should be well on your way to building up and quieting down your new carpet.
Thanks for the useful information.
To clarify, The floor I want to treat is the upper floor. Currently there is carpet there- wall to wall.
I peeled back a bit of carpet and looks like a wood underlayment. I don't know that its a hardwood floor or what it is made from.
Would this product still be appropriate.
this product says it it for : ceramic tile, porcelain tile, stone, marble, engineered hardwood and laminate floors
Also the dimensions are 10 x 13
Does this product come in rolls. Would that work better.
Have you heard of green glue. Would that work as an addition sound reducer in this case
and no squeaks luckily
Good morning stev,
Thanks for joining us here on the community, lets talk about sound reduction and your new carpet.
As being a 2nd story tenant in a noisy old hardwood floor apartment with a complaining neighbor underneath, I understand you wanting a nice quiet floor.
I'm glad you did your research on this, since lots of people just think that a simple fix of a new pad and carpet will solve this issue. There are many ways to increase sound reduction in your floors, and depending on what the floors condition now can and will factor in this. For example, if you have squeaky wood floors, you'll need to solve that problem first. For pure sound deadening, installing a system with sound reducing fasteners (rubber washers alongside the screws) is the best solution for sound reduction and deadening. That is done so as to allow air between the layers of your new floor and the subfloor is the best way to go. While this would involve building a new subfloor and raising it, it maybe too much for this project, but it is something to possibly consider.
Of all of the items you chose in your post, the very first one is the absolute best material to use for sound reduction. The other 2 materials you listed are strictly for laminate flooring and would not be suitable for this install. Cork is really the best material for this situation, it's affordable, easy to install and works great for reducing sound transmission.
After inspecting the existing floor, checking for squeaks and noise, you can install the cork underlayment. Be sure to glue this down to ensure a nice and even underlayment. As for the adhesive to use, only use a glue rated for cork underlayment, like the one shown below...
After letting the cork underlayment dry out overnight or 24 hours, you can now place the pad and carpet. Believe it or not, a good carpet pad will give you more sound reduction on top of the great cork underlayment already placed down. A pad with at least 6 lb. weight will give you substantial sound reduction. Depending on what carpet you choose will depend on what pad to obtain. By consulting a Home Depot flooring specialist at your local store, you can elminate any guess work from having to decide which one to pick.
So to reduce the sounds of the TV, refrigerator, and voice; using the items listed above should get you well on your way to have a much quieter floor.
Any further questions please do not hesitate to ask,
