Does anyone have any knowledge/experience of underlay for floating engineered wood flooring on a concrete base?
From some cursory reading it seems that there are varying thicknesses, tog ratings, sound insulation etc and of course price. My initial thoughts are that a decent thickness and tog rating could be beneficial on a ground floor, however I wondered if this would lead to sponginess/springiness underfoot? Perhaps it's a good thing having some 'give' and it may make it a bit quieter to walk on? Speaking of sound, I am assuming the 'sound deadening' underlays are more to minimise transmission of noise *through* the underlay (to rooms below) and not for reducing floor-related noise within the room itself?
