Went to the floor store yesterday to look at the "floating vinyl sheet" the guy was telling me about. OMG this stuff is great! It is made by earthscapes and there are other brands made by armstrong etc. (available at HD @1.44 sqft). But i found the HD stuff is not as strong as the earth scapes. This is a free floating sheet, not glue required. I tested this product on a sample sheet (2 x 3) and threw it on a slick bamboo floor and this did not slide at all! further more I took my keys and tried scratching it. no luck. I was very impressed. I am going to get this stuff at $1.61 sqft. Problem is that it only comes in 13 foot wide rolls.
I was really, really impressed. You can found crimp and try to bend it out of shape and it goes back to laying flat with out a crease. neat stuff. I couldn't find any website info...or I would post link here.
