For what it's worth, when we were deciding on what kind of flooring to use I took samples and did some testing. 3 different samples of cork flooring, 1 of bamboo, 2 of different quality 'pergo' type floors, and a lower cost oak. I used my Buck 7.5'' blade hunting knife and dropped it point down on each sample from about 6'. Then I dropped it handle first, then I dropped a can of beans on to it so the rim would hit first. Then I placed a chair on each sample and sat down with my wife on my lap (no lude comments please) to simulate an overweight guest at dinner, or a heavy appliance. Kind of silly, but we have some very overweight friends. NOT THAT THERE'S ANYTHING WRONG WITH THAT!!! Last was a little light sanding. All the results pointed me to the bamboo.
-The point drop test resulted in the cork floor tearing up chunks, the laminate chipping, and the bamboo and oak simply getting stuck with the smallest noticeable mark. The Bamboo I could futz with and reduce the size while the oak was what it was.
-For the blunt point drop, the cork dented but rebounded after an hour or two, the cork showed a small dent, the Oak about the same. The pergo dented and chipped.
-The can drop was similar to the blunt point, but the oak showed no damage and the bamboo had a marred finish. The cork didn't rebound as fast. The pergo had no damage.
-The chair test showed no damage to oak and bamboo or pergo, but the cork had a good sized dent that was still slightly dimpled after a couple hours.
-I don't remember the sanding results. Sorry.
I decided I didn't want the dents and dimples of the cork and I didn't like the fact that you could pull up chunks...not with my kids terrorizing it!
The laminate chipped too frequently and I don't like the look and feel as much.
We went with bamboo because we liked the look and $$ better than oak.
As always, if you want a thourough analysis, go to MUD.
I believe we got our samples from ifloor.com for a couple bucks each. They have a good price for larger volumes, like 2000 sq feet, but we were just doing the kitchen. Pretty good selection. I personally would put cork in the living area and something harder in the kitchen. I liked the look and feel of cork, just not for the kitchen.
