Floor insulation method?

If you want cork in panels look at https://www.widgetco.com/
I bought their panels 2’x3’, I think, to use as a floor in my laundry room
I just used wood glue to stick them down then sealed the top with a light gray stain
It worked great, and it’s very quiet
The panels were a lot cheaper than regular cork floor tiles and were quicker to install, since they were larger.
They are listed as underpayment, but I used them as the finished floor. Cork is cork. Seal it and you are good to go
In the panels the cost is as low as 48¢sf for the 1/8”, but you might want to go with 1/4” for more insulation value but still only about $1sf
They also have 1/2” and you could use more than one layer if you wanted thicker.
