Laminate Underlay?

So as per my previous posts on here, i have now grinded all the bitumen off my floor ready for my surface DPM to go down.

Got to start ordering the laminate and underlay again!

Before i used tis stuff http://www.empirefloors.co.uk/en/barrier-plus-underlay-404

Now i want to put some better stuff down as this did nothing to supress moisture.

Reading around Duralay Timbermate excel gets high reviews?

Is this good stuff?

If not what underlay do u laminate boys recommend?

Thanks

 

Quickstep combilay would be better for you, or cushion wood.

 

i'm all for cush'n wood, good underlay although excel isn't too shabby either. Personally i'd use seperate dpm sheet with a decent rubber just tape all the joints and run up the wall which you trim one fitted.

 

something like this you mean?

Not sure im looking for the right things about rubber underlay, do you have a link as an example please?

Also im hoping not to take my skirting boards off (as they are screwed and gripfilled to f**k to fit my massivly uneven walls!!!!) so would not sure id be able to "run up the wall"?

 

Run the Dpm sheet up the wall by 25mm then cut to laminate thickness once fitted.

 

Yep that's a vapour barrier then use an,underlay on top like duratex

 

Thankyou.

What benefit would dpm + rubber give me over say the cush n wood?

Or is it just personal preference?

 

personal preferance, although doing them seperately you can get a better vapour barrier than the ones attatched to the underlays like a full 1200 miron dpm overlap the joints by 20mm and tape together much better barrier than standard.

 

Thanks Matt,

So in my situation:

I have a concrete subfloor that sucks mositure up through it so is going to be above 75% RH most of the time!

I am putting a surface liquid DPM down now i have scraped the bitumen residue up from the plastic tiles.

So can i lay underlay (eg cush n wood) directly on the surface DPM or do i have to have a DPM sheet and then underlay on top?

 

i would inyour situ use a seperate dpm sheet and then cush n wood just to be safe its not going to break the bank.if you can use a continuos sheet (no joins) if not overlap by at least 30mm and tape also tape joins on underlay.
