Laminate Flooring on concrete garage floor

[JKami84]

Hi, 

I am partitioning some of my garage for utility space - and will be heavily insulating the ceilings and walls. With the floor, I am constrained by ceiling height so want to achieve the best I can within 10-15mm including the laminate flooring. I know that the best insulated flooring would need much thicker products, but I am happy with just "comfortable on the foot" for flooring given how much I've achieved with wall and ceiling insulation.

 

I first considered 6mm tile backer boards (with good thermal stats) to go directly on the concrete, followed by standard underlay for laminate, then the laminate itself. That is 3 layers (inc. the laminate).

 

But can I achieve good thermal properties and the flooring itself in just 2 layers? e.g. is there a product that covers what I want? 

 

I saw the below which is 5mm....

Any advice welcome.
