Best vapour barrier for bitumin/asphalt floor

[Durutti]

Hi folks, sorry if this is a daft question but no amount of Internet searching has answered it.

I'm currently about to install a laminate floor in the dining room. The floor is bitumin/asphalt (the black, hard, rubbery stuff) and I want to do a proper job. I've decided to get the fibreboard underlay from wickeS as it gets decent reviews and is fairly cost effective plus the floor has plenty of holes and the odd slight crack.

My question is do I need a vapour barrier underneath the underlay?
Also, will this one do http://m.wickes.co.uk/mt/search.wickes.co.uk/search?w=Vapour barrier&asug=&un_jtt_redirect

Cheers in advance for any replies.[/b]

I have previously fitted a solid wood floating floor over an asphalt floor over fibreboard underlay and did not use any sort of vapour barrier. 7 years later its still fine.

Asphalt is the floors DPM. As it has cracks and damage it defo requires a barrier sheet. What you have found is fine.
