Husband and I went to Home Depot looking for cork flooring. Home Depot had two samples up of cork flooring and they were in a plank style, as opposed to the cork pattern. The only sample we could obtain of cork is a muddy color brown. Holding it up to the sie looks like 3/16 cork, the rest fiber board and the bottom has 1/16th of cork. This is going for $3.98 a yard and is called Smoky Mineral Plank Cork, although the front has no plank pattern. It is 5 1/2" Click. We then went nextdoor to Office Max and bought two laptops.... one for me, one for his mother. Go figure.
Next stop was Carpet Liquidators. The had Belgium Blocked Cork FLooring by Pacific Mat. The thickness of the cork layer on the plank was far bigger than Home Depot and it was also $3.98 (on sale). It seemed far better quality, but I didn't care for the mosaic and wanted a plank. It has 3 coat Urethan finish and an MDF core. The planks were 11 5/8 x 36" for total thickness of 10.5 mm. It just seemed higher quality. It was usually $4.99 per sf.
