The thing is there is already an isorubber underlay stuck to the floor.
Can I use duratex between the rubber underlay and the laminate?
Or will this cause the boards to move?
I've noticed that duralay duratex doesnt have a dpm. Is this something i need?
The underlay will go between the isorubber (glued on the floor) and the laminate.
If i use an underlay which has a dpm (like selitac from B&Q) could this cause issues with moisture if it sits between the isorubber...
Thanks. If I use something like duralay over the isorubber is there a risk of bounce?
The developers told me that their own floor fitters lay the laminate directly on the isotubber.
I've bought a new build flat and i chose it without flooring. Over the concrete floor they have put an isorubber top which looks like the image in the link below:

I'm wondering whether I need to put down some underlay before the laminate...
