Our apartment has laminate flooring - creaks! Just walking normally over it makes it creak all the time. At night when people are sleeping it is disturbing.
With the construction of thin flexible flooring laid on a thin foam layer it is moving all the time, between the different slats. Of course it will creak.
I consider that is a design problem of the system, which is not acceptable. I would appreciate opinions on whether we have a case to request replacement with a suitable and correct alternative.
It was installed before we moved in, so that makes it a few years now -- I guess that we have no recourse to anything. It does seem a bad design though, not due to poor installation - just bad design.
