Thin Floor Insulation

hi Folks,

I am taking up all the laminated floors in a new(old) house I have just bought. I need to redo the whole plumbing.
While the are up, I might as well put down some floor insulation. But it cannot be too thich as the door would not close/open and the door saddles are very low. Also i will be replacing the laminate.
Its a bungalow around 1650 sq ft.

Any suggestions?

Thanks a lot,

John
