I’m hoping to learn from experienced and/or expert GBA members about high-end cork flooring. We’ve had Ipocork glue-down tiles (“The Ipocork brand is specially designed to serve the commercial grade cork market with WRT finish”) for ten years on our kitchen floor, and it looks like new. But Ipocork is no longer available.

We’re looking for glue-down tiles or “planks” for a new kitchem

I have a pretty solid, basic understanding of categories and products, but the product descriptions use a number of “magic” (i.e., marketing) terminology and often eliminate important specs.

I’ll start with what I know:
* Float versus glued: I’m interested only in glued, which is where I find better materials and which provide better stability
* “Veneer” (slice) versus “Agglomerated” (boned small granules): The surfaces look different, of course. I don’t know whether there’s difference in wear resistance, or if it matters with a protective film/finish on the surface.
* Density: Outer bark is denser than inner bark. Agglomerated can be produced at different densities. Denser is more durable; less dense provides more cushion.
* Thickness: A thicker layer of cork will produce more cushioning. At least one product offers a thick cork tile that can be refinished, like hardwood.
* Solid versus engineered: Many products use multiple plies, which include MD or HD layer(s) to provide structural strength. It’s not clear how putting a “cushioning” layer of agglomerated cork under an MD/HD layer doesn’t diminish the cushioning effect of the lower layer.
* Tile finish: There are unfinished tiles, which require finishing after installation, and a variety of treatments and films. With hardwood floors, I believe it’s better to use only penetration oil, rather than a film such as urethane or aluminum oxide, to enable repairing dings and full resurfacing,
* Grade: Commercial and Residential ratings. A typical “high end” product might be 33/23.
* Number of Years Warranty: Wear and/or warping or other failure. 

Unfortunately, a lot of the products are now “floating.” Among them are the Amorim Wicanders Wise “Essence,” which appears to have the most durable of Amorim’s product lines.

I’m considering still selecting it and gluing it down.

APC Cork Flooring appears to make potentially good “adhered” tiles.

I (and perhaps a lot of others who are considering cork) would greatly appreciate insights, experiences, and advice.
