Quiet Rock is not so Quiet
Posted by on
SUNNYVALE, CALIFORNIA -- Save money by choosing a sound proofing material other than Quiet Rock. At $39.95 a sheet for half inch board, I thought the material would do a great job of blocking sound coming from the townhome kitchen next door. I even had it installed the entire length of the party wall, so that there would no chance to sound to make it through. HA! I still hear cabinet doors, the microwave door, and Nascar racing through that wall.
I suppose it is possible that the three fourth inch material would have worked better than the half inch, but it would have cost even more. So, before you invest in Quiet Rock soundproofing sheet rock, investigate all sound proofing options. You might find a better product for a more reasonable price. Quiet Rock/Quiet Solution is a division of Serious Materials Company.

The thicker the better.
Consider yourself lucky, I have a woman above me that trounces around with her cats at four in the morning.

there is much more to do for sound proofing then adding a sound dampening wallboard. did you add extra rockwool to the inside of the wall? is there sound dampening wallboard on the other side of the wall as well?

sorry zz, I will try and keep it down.

I think QuietRock is the most effective of all soundproofing materials. Wonder why it didn’t work for you. It’s performed great for everyone else who’s used it.

GellerGeorge, you work for them. You are not a consumer.

In general the low cost "soundproof" drywall doesn't isolate much more than standard drywall of equal mass. The reason is there isn't much damping material in between the drywall layers.

Much better to use standard 5/8" drywall ($7 a sheet) and firld apply the damping material yourself. Higher performance, lower cost.

I have to say this: After all the hype of Quiet rock on the internet the reality is that after using the new ez snap ( no metal) the improvement was minimal. ON my party wall I no longer hear mid range voices but still hear music speakers and loud voices. On the exterior wall we also added quiet batt insulation, calked any all cracks at floor and ceiling and there was no noticeable improvement in train or airplane noise. Green Glue was used on studs, silent seal in all areas. This product is waste of money unless you hire someone who is an acoustical engineer and they can guarantee results or your money back. It's not like Quiet Rock is going to give me my money back. I want to save people this dissapointment.

Air is the best insulator against sound and temperature. Has anyone added an air gap to improve the effectiveness of their project?

I was hoping tpfind info that said "under the same noise levels, Quiet rock let through _____decibles compared to 5/8 sheetrock that let through __________decibles.
