Green Glue Calculator

Customers Questions and Answers

1) Royce L: How would you reduce the sound of a wall fans. Would I de couple the main wall then use this product?

Trademark Soundproofing Reply: Hi Royce, If the sound is vibrating to the other side of the wall. Then yes.

2) Steve S: In the case where you want the "best" solution and apply 3 tubes/4x8 sheets of drywall and the calculator says you need 4 cases of the tubes to do 435 sq.ft., how many buckets would you need for the same "best" coverage?

Trademark Soundproofing Reply:

You would need 2 green glue buckets.

3) Matthew M: I am designing a multifamily new construction project and need to specify a floor assembly that meets both STC and IIC ratings of 50+. Are there rated systems that use Green Glue between subfloor layers? I would like to avoid using gypcrete on the project, which seems to be the most prevalent approach. Thanks for your help!

Trademark Soundproofing Reply: Hi Matthew. We have asked our tech dept to email you an STC floor test utilizing Green Glue.

5) Doug Ga: I am renovating a basement and plan on a double, 5/8 type X drywall ceiling on joists 16" O/C. What would the STC rating increase be if I apply one, two, and three tubes of your product per sheet? The area is approximately 800 square feet. Thanks, Doug Galloway

Trademark Soundproofing Reply: 2 tubes will add 9 STC points. 1 Tube about 5 STC points and 3 Tubes about 10. 2 Tubes is the way to go.

6) Peter: I have a 300 square foot basement with the plan to use quietrock as the lid component. Unfortunately, I was not advised by the insulation contractor that the spray in foam insulation we applied is not good for sound even though I specifically mentioned it many times over. I am trying to solve the problem now before drywall. My construction is 2 x 12 and we have 9 inches of sprayed foam insulation in the floor I was considering after reading many posts to install five eights drywall and then the quiet rock. Would it be a prudent practice to apply the green glue between the two layers of drywall? Right now with no drywall in place I get almost 100% sound transfer through the phone which has become very disappointing. Please help. Ceiling height is a mere 7 ft so the footsteps are very close to ear level when you are in the space.

Trademark Soundproofing Reply: It would help with about an extra 4 STC points. For footstep noise you would really need to decouple the ceiling and/or add a rubber underlayment on the floor above.
