Soundproofing under hardwood

[ben]

I'm currently working on a project. The customer wants soundproofing under the hardwood floor. He doesn't want to lose too much space as the ceiling is less than 8 ft as is. I was considering QT 5 mm. Does anyone know how effective that is? Or any other suggestions?

Do you guys nail through it or sandwich it under new underlayment? That sound stuff always confuses me cus out here it's almost all concrete.

Rubber is one of the best sound proofing products available. But is it overkill?

 

[ben]

Never nail with soundproofing. That would basically defeat the impact absorption

 

[Ernesto]

If yer fastening through the soundproofing your defeating the purpose of the sound proofing. It is all a joke unless it is sandwiched between underlayments.

There's an echo in here.

Isn't qt designed for a double glue install?

So is Sound Solutions from Healthier Choice. Never used it for a double glue, it's made out of soybean.

 

[ben]

Of course I'm doing double glue down! I just wish it would be possible to know the approx results before I start working

 

[ben]

I always knew that with glue down you must use engineered wood. Solid wood has to be nailed down. Is this true?

 

[rugaddict]

you can glue down solid---them arizona boys do it all the time---engineered can be stapled down--some can be floated---tomorrow there will be something new
