We are also facing the decision of whether it should be the Modular One Oak Pure Nature LHD. It is to be installed in the upstairs children's room and bedroom, which is why impact sound is a particular concern for us (two children, 3 and 5). Compared to the Basic 30 vinyl, which is slightly thicker, the Modular One is supposed to be somewhat louder. With the sample planks, we can perceive a slightly brighter sound with the Modular One than with the Basic 30, but does that really make a difference in everyday life? What are your experiences?
