Laminate flooring

[jumpsystems]

I'm thinking of laying wood laminate flooring in my lounge. The existing flooring is concrete with vinyl tiles under carpet. Should I retain the tiles for insulation purposes, or is there a better way of insulating the floor?

Thanks for any advice.

I would leave the viynl tiles, they will not act as an insulator, but removing them is hassle that will not affect the new floor (unless it makes the laminate too high). As for insulation, there are a number of different underlay materials for laminate floors.
