Question from CZ
Do you have any information about the kind of binder used in manufacturing cork floor tiles? ?
I just learned that cork floor tiles are not solid cork but they’re made from cork granules and a binder pressed together. I’ve been reading about cork flooring for months and never heard this. It’s disconcerting that makers and retailers never mention the binder (much less identify it by name). Today I came upon one manufacturer’s website where they did mention a binder. I’d buy from them except they’re above my budget.
Every cork product description says “hypoallergenic” but I never see testing information mentioned. Even if cork is traditionally low tox, it’s important to know exactly that ingredients any company is using to make their tiles, the binder and the surface finish. And I’d like to know the maker has a clear commitment to safe ingredients.
I was hoping to use cork to cover a very bad floor in my family room because I must sell my house soon. (Low tox plywood was going to be the subfloor). Cork seemed something I could afford and safely live with until my house sells. Lumber Liquidators has had good prices on plain cork floor tile. I’ve just left them a message asking what binders and surface finishes are used in manufacturing the tiles they sell. Thanks for this opportunity to vent but also I’d appreciate any further info and feedback.
This leads me to ask you and your readers if you have any recommendations about flooring that is clearly low tox and that is low cost. Thanks much.

Experience anyone?
Let me know what Lumber Liquidators says and I can tell you if it’s toxic or not.

From what I’ve read, there are cork products that have synthetic binders, and there are those that have a natural resin, suberin, as a binding after heating the cork particles. The suberin is naturally occurring in the cork. You have to ask what the binding agent is.
