Advice on laminate underlay...

[dpm_dpmartin]

Good morning,

I have 34 square metres of a downstairs terrace that I want to cover completely in laminate. The kitchen will eventually be a tongue-and-groove 22m chipboard surface, the dining room will be a concrete surface and the small hallway and living room will be floorboards. I'll have a complete run of laminate throughout.

Am I OK using the same underlay with an in-built DPM across the entirety of that (chipboard, concrete and wood)? I was looking at this:

http://www.screwfix.com/p/acoustalay-foam-underlay-with-dpm-3mm-18m-green-blue/45461

Which appears to have good reviews and isn't a terrible price (for 2 packs, which is what I'm thinking I shall need).

I also saw this at B&Q, which is like a jigsaw and clearly says it's suitable for all types of subfloor.

Any other recommendations would be gladly listened to... I don't have a budget in mind, just don't want to go stupid money or dirt cheap and useless.

Alright guys - no bites on that but has anyone tried this product as of yet?

Seems reasonably priced... and comes in bright red! Oooh.

I am also looking at laminate underlay so excuse me for jumping in on this thread. Was this the stuff you mentioned at B&Q? http://www.diy.com/departments/seli...rene-laminate-floor-underlay-5m/252020_BQ.prd

This claims that it has a built in DPM I want to know is whether you need a separate membrane to go up the sides of the wall? I had heard that you should tank up the walls an inch or two with DPM, but this stuff, being rigid sheets, can't go up the walls.

Indeed, the Selit stuff...

I think I'm going to try this red Roberts stuff. After all, it's rather important that it's nice and colourful.
