Cork Flooring?

post #1 of 12
Thread Starter 
Anybody have an opinion on cork flooring. I have hear many of the positives such as: Thermal barrior from basement floor, environmentally friendly, moisture resistant. Does anybody know the sound implications? What is the best flooring for a HT/Game Room?

From what I hear, it is very sound absorbent.

Maybe not.

The NRC of 3/4" cork is .1 to15.

The NRC of carpet over foam is as high as .55.

See http://www.nrcratings.com/nrc.html

If you are more concerned about transmission through the floor this site has some numbers for the STC of a cork product). http://www.quietcork.com/testing_results.html

Correct. A cork floor is a poor sound absorber. It is good a reducing impact (footstep) noise, but so is carpet.

No need for an apology! You probably did hear that cork floors were very sound absorbent. This is one of many acoustical fallacies spread by contractors and even manufacturers.

So if cork is not as good for an HT, what should one use in construction of a basement ht when carpet is out of the question?

An absortive ceiling can compensate for a reflective floor. Quality acoustical ceiling tiles (fiberglass construction, such as Armstrong Optima) can be fastened directly to a drywall ceiling. This does not to compromise sound isolation, as might a suspended ceiling.

Definitely check on the manufacturer's signoff to use in a basement. I know that when we installed cork planks in our kitchen, there were some large warranty invalidation terms that included use below grade.

By the way, the cork floors are great: they look and feel delightful.

it might smell like wine

Just something to keep in mind too: cork flooring will fade over time if exposed to the path of direct sunlight. There are multiple windows in my basement (south facing) and this would be an issue if I used cork. Just and FYI. It is a good insulator from cold though :-)
