Foil Insulation Between Concrete Floor and Porcelain Tiles

Hi, first post on this site, first bit of diy for me after buying my house.

I am having porcelain wood effect tiles on the hallway downstairs and new carpets stairs and landing.

The hallway floor under the existing carpet is concrete. I have a friend who has rolls of left over foil bubble style insulation and doesn't want to throw them in the skip.

Thanks so much for your time.
