Topic: Product & Installation Information / Environ II in basement under wood

Thanks for the reply. So, let me see if I’ve got it straight.

Kahrs does not have the underlayment attached, but they do require their own underlayment to keep the warranty in place. You recommend cork as an insulator over concrete, I believe.

So is this recommended sequence: concrete floor, cork, Kahrs underlayment, heat mat, wood flooring?

I am considering using the Environ II system in our basement under Kahrs floating engineered hardwood.

I’m a little confused on the underlayment…I read that an insulating over concrete is recommended. Is that in addition to the Kahrs’ underlayment?
Where are the Environ mats installed, directly beneath the wood?

Edit: the title should say under wood
